Shoulder & Elbow

In 1974, Tommy John of the Los Angeles Dodgers was 31 and a 12-year veteran of Major League Baseball when he became the unwitting vanguard of a revolution in baseball and orthopedics. Fifty years later, Mr. John might not be a candidate for the latest advances to a procedure that bears his name.

The southpaw pitcher had faced the abrupt end of his career when, after one fateful delivery, he found himself unable to throw to home. So he took a gamble on the surgical equivalent of a Hail Mary: the reconstruction of a torn ligament in his pitching elbow.

The experiment was a wild success. Mr. John pitched— and better than he had before — for another 14 seasons, retiring in 1989 at the age of 46. How much better? After the surgery, he tallied three 20-win seasons compared with none before the operation, and he finished among the top five vote-getters for the annual Cy Young Award three times. He was named an All-Star once before the surgery and three times after.

The triumph notwithstanding, Tommy John now cautions against Tommy John surgery. What’s given him and clinicians pause is a trend in recent years of ever-younger athletes who undergo the procedure.

Along with the surgical improvements in repairing a torn ulnar collateral ligament (UCL) is a demographic shift toward school-aged athletes who get it. By 2014, one study concluded that 67.4% of UCL reconstruction surgeries were performed on athletes between 16 and 20 years of age. Some patients are still in Little League when they undergo the procedure.

Experts say these athletes have weakened their UCLs through overuse. They disagree on whether to call it an “epidemic,” but if it is, “the vaccine is awareness” against throwing too hard and too often, said Eric Makhni, MD, an orthopedic surgeon at Henry Ford Health in Detroit.
 

From Career-Ending to Routine

Mr. John’s entry into baseball and orthopedic lore was initially slow, but the trickle turned into a tide. After Frank Jobe, MD, swapped a healthy tendon from John’s right wrist for his worn and torn left UCL on September 25, 1974, he didn’t perform his second surgery for another 1194 days. By the time “Tommy John surgery” became a recognized phrase, Mr. John was still active but only 14 professional baseball players had undergone the operation.

Prior to the start of spring training this year, an oft-cited database listed 366 pro players who’d undergone the operation. 

“Before Tommy John, that was a career-ending injury,” said Grant E. Garrigues, MD, an orthopedic surgeon at Midwest Orthopaedics at RUSH in Chicago, who called Mr. John “a pure revolutionary.”

Tommy John surgery is “the only one that I can think of that is named after the patient rather than the doctor who first did it,” said Patrick McCulloch, MD, an orthopedic surgeon in Houston and a team physician for the Astros.

Dr. McCulloch, who performs about 25 UCL repairs a year, said that by recent estimates, one-third of pro pitchers had had some sort of surgical repair. He hesitated to call the increasing number of operations an epidemic but acknowledged that the ingredients exist for more elbow trauma among baseball players.

“More people are playing more often, and people are bigger and stronger and throwing harder,” he said.

Either way, Dr. McCulloch said, “the procedure is a victim of its own success” because it is “just done phenomenally well.”

The surgery is now commonplace — perhaps too commonplace, said David W. Altchek, MD, attending surgeon and co-chief emeritus at Hospital for Special Surgery in New York City.

Dr. Altchek played a key role in the popularity of the operation. Twenty-two years after Mr. John’s surgery, he helped develop a variation of the procedure called the docking technique. 

Whereas Dr. Jobe sutured Mr. John’s replacement graft to itself, “we developed a different way of tying it over a bone bridge, which was more secure and more easy to tension,” Dr. Altchek explained.

The advance meant less drilling into bone and enabled surgeons to avoid moving a problem-free ulnar nerve or removing the flexor-pronator muscle that protects the elbow from stress. “The trauma of the surgery is significantly less,” he said. “We just made it a lot easier very quickly,” cutting the surgery time from 2 hours to 30-40 minutes.

Maybe the surgery became too easy, said Dr. Altchek, who estimates he has done 2000 of them over the past 30 years. “I don’t want to condemn my colleagues, but there are a lot of people doing the surgery,” he said. “And not a lot of people are doing a lot of them, and they don’t know the nuances of doing the surgery.”

The older procedures are known as the “full Tommy John”; each has a 12- to 18-month healing process, with a success rate of 80%-85%. Pitchers typically sit out a season while recovering.

Brandon Erickson, MD, an orthopedic surgeon at Rothman Orthopaedic Institute in New York City, said that in younger patients he has recently turned more often to the suture of the future: an internal brace that provides a repair rather than reconstruction.

The procedure, pioneered by Felix H. Savoie III, MD, the Ray J. Haddad Professor of Orthopaedics at Tulane University School of Medicine in New Orleans, and Jeffrey R. Dugas, MD, of Andrews Sports Medicine & Orthopaedic Center in Birmingham, Alabama, uses collagen-coated tape that looks like a shoelace and provides a scaffold that Dr. McCulloch said “is inductive to healing and growth of ligament tissue.”

The brace is intended for an “overhead” athlete (mostly baseball players but also javelin throwers and gymnasts) whose UCL is torn on only one side but is otherwise in good shape. In a pitcher the same age as Mr. John was when Dr. Jobe performed the first procedure, “that ligament may not be of very good quality,” Dr. McCulloch said. “It may have thickened. It may have calcifications.” But for a high-school junior with aspirations to pitch in college or beyond without “way too many miles on the elbow,” the approach is a good fit. The healing process is as little as 6 months.

“The ones who have a good ligament are very likely to do well,” said Dr. Erickson, an assistant team doctor for the Philadelphia Phillies.

“If the patient’s ligament is generally ‘good’ with only a tear, the InternalBrace procedure may be used to repair the native ligament. On the other end of the spectrum, if the patient’s ligament is torn and degenerative the surgeon may opt to do a UCL reconstruction using an auto or allograft — ie, Tommy John surgery,” Allen Holowecky, senior product manager of Arthrex of Naples, Florida, the maker of the InternalBrace, told this news organization. “Before UCL repair, Tommy John surgery was the only real treatment option. We tend to see repairs done on younger patients since their ligament hasn’t seen years of use-damage.”
 

Calls for Caution

Tommy John III wanted to play baseball like his dad until near-fatal complications from shoulder surgery altered his path. He was drawn to chiropractic and consults on injury prevention. “All surgeries and all medical interventions are cut first, ask questions later,” he said. “I was born with that.”

He saw his dad’s slow, heroic comeback from the surgery and described him as the perfect candidate for Dr. Jobe’s experiment. Tommy John spent his recovery time squeezing Silly Putty and throwing tennis balls. “He was willing to do anything necessary. He wanted to throw. That was his brush.” When the son was recovering from his own injury, “he said, ‘Learn the knuckleball.’ I said, ‘I don’t want to. I’ve reached my point.’ ”

He said he tells young patients with UCL injuries to rest. But instead “we have year-round sports with the promise that the more you play, the better,” he said. “They’re over-activitied.”

According to the American Academy of Orthopaedic Surgeons, 6.4 million children and adolescents in the United States played organized baseball in 2022, down from 11.5 million in 2014. Nearly half of pitchers played in a league with no maximum pitch counts, and 43.5% pitched on consecutive days, the group said.

How many UCL repair or reconstruction surgeries are performed on youth athletes each year is unclear. A 2019 study, however, found that although baseball injuries decreased between 2006 and 2016, the elbow was “the only location of injury that saw an increase.”

Dr. Garrigues said some parents of throwing athletes have asked about prophylactic Tommy John surgery for their children. He said it shouldn’t apply to pitchers.

“People have taken it a little too far,” he said. Dr. Garrigues and others argue against children throwing weighted balls when coming back from surgery. Instead, “we’re shutting them down,” he said.

Throwing any pitch is an act of violence on the body, Dr. Garrigues said, with the elbow taking the final brunt of the force. “These pitchers are functioning at the absolute limits of what the human body can take,” he said. “There’s only so many bullets in a gun,” which is why pitchers often feel the twinge of a torn UCL on a routine pitch.

Dr. Makhni suggested cross-training for pitchers in the off-season instead of playing baseball year-round. “If you play soccer, your footwork is going to be better,” he said.

“Kids shouldn’t be doing this all year round,” said Rebecca Carl, MD, associate professor of pediatrics at Northwestern University Feinberg School of Medicine in Chicago. “We are recommending that kids take 2 or 3 months off.” In the off-season, she urges them to strengthen their backs and cores. 

Such advice can “feel like a bombshell,” said Dr. Carl, who chairs the Council on Sports Medicine and Fitness for the American Academy of Pediatrics. ‘Some started at a very young age. They go to camps. If I say to a teenager, ‘If you do this, I can keep you from getting injured,’ they think, ‘I won’t be injured.’” Most parents, however, understand the risk of “doing too much, too soon.”

Justin Orenduff, a former pitching prospect until his arm blew out, has made a career teaching head-to-toe pitching mechanics. He founded DVS Baseball, which uses software to teach pitchers how to properly use every muscle, starting with the orientation of the back foot. He, too, argues against pitching year-round. “Everyone on that travel team expects to get their fair share of playing time,” he said. “It just never stops.”

Organized baseball is paying attention. It has come up with the Pitch Smart program that gives maximum pitch counts for young players, but experts said children often get around that by belonging to several leagues.

Dr. Altchek said some surgeons have added platelet-rich plasma, stem cells, and bone marrow during surgery to quicken the slow healing time from UCL replacement. But he said, “it has to heal. Can you speed up biology?”

Dr. McCulloch said that, all the advances in Tommy John surgery aside, “the next frontier is really trying to crack the code on prevention.”

The European Society of Cardiology guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery have seen extensive revision since the 2014 version.

They still have the same aim – to prevent surgery-related bleeding complications, perioperative myocardial infarction/injury (PMI), stent thrombosis, acute heart failure, arrhythmias, pulmonary embolism, ischemic stroke, and cardiovascular (CV) death.

Surgeons_Operating_Theater_web.jpg

Cochairpersons Sigrun Halvorsen, MD, PhD, and Julinda Mehilli, MD, presented highlights from the guidelines at the annual congress of the European Society of Cardiology and the document was simultaneously published online in the European Heart Journal.

The document classifies noncardiac surgery into three levels of 30-day risk of CV death, MI, or stroke. Low (< 1%) risk includes eye or thyroid surgery; intermediate (1%-5%) risk includes knee or hip replacement or renal transplant; and high (> 5%) risk includes aortic aneurysm, lung transplant, or pancreatic or bladder cancer surgery (see more examples below).

It classifies patients as low risk if they are younger than 65 without CV disease or CV risk factors (smoking, hypertension, diabetes, dyslipidemia, family history); intermediate risk if they are 65 or older or have CV risk factors; and high risk if they have CVD.  

In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:

First, recommendations for preoperative ECG and biomarkers are more specific, he noted.

The guidelines advise that before intermediate- or high-risk noncardiac surgery, in patients who have known CVD, CV risk factors (including age 65 or older), or symptoms suggestive of CVD:

• It is recommended to obtain a preoperative 12-lead ECG (class I).
• It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
• It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).

However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).

Troponins have a stronger class I recommendation, compared with the IIA recommendation for BNP, because they are useful for preoperative risk stratification and for diagnosis of PMI, Dr. Halvorsen explained. “Patients receive painkillers after surgery and may have no pain,” she noted, but they may have PMI, which has a bad prognosis.

Second, the guidelines recommend that “all patients should stop smoking 4 weeks before noncardiac surgery [class I],” she noted. Clinicians should also “measure hemoglobin, and if the patient is anemic, treat the anemia.”

Third, the sections on antithrombotic treatment have been significantly revised. “Bridging – stopping an oral antithrombotic drug and switching to a subcutaneous or IV drug – has been common,” Dr. Halvorsen said, “but recently we have new evidence that in most cases that increases the risk of bleeding.”

“We are [now] much more restrictive with respect to bridging” with unfractionated heparin or low-molecular-weight heparin, she said. “We recommend against bridging in patients with low to moderate thrombotic risk,” and bridging should only be considered in patients with mechanical prosthetic heart valves or with very high thrombotic risk.
 

More preoperative recommendations

In the guideline overview session at the congress, Dr. Halverson highlighted some of the new recommendations for preoperative risk assessment.  

If time allows, it is recommended to optimize guideline-recommended treatment of CVD and control of CV risk factors including blood pressure, dyslipidemia, and diabetes, before noncardiac surgery (class I).

Patients commonly have “murmurs, chest pain, dyspnea, and edema that may suggest severe CVD, but may also be caused by noncardiac disease,” she noted. The guidelines state that “for patients with a newly detected murmur and symptoms or signs of CVD, transthoracic echocardiography is recommended before noncardiac surgery (class I).

“Many studies have been performed to try to find out if initiation of specific drugs before surgery could reduce the risk of complications,” Dr. Halvorsen noted. However, few have shown any benefit and “the question of presurgery initiation of beta-blockers has been greatly debated,” she said. “We have again reviewed the literature and concluded ‘Routine initiation of beta-blockers perioperatively is not recommended (class IIIA).’ “

“We adhere to the guidelines on acute and chronic coronary syndrome recommending 6-12 months of dual antiplatelet treatment as a standard before elective surgery,” she said. “However, in case of time-sensitive surgery, the duration of that treatment can be shortened down to a minimum of 1 month after elective PCI and a minimum of 3 months after PCI and ACS.”
 

Patients with specific types of CVD

Dr. Mehilli, a professor at Landshut-Achdorf (Germany) Hospital, highlighted some new guideline recommendations for patients who have specific types of cardiovascular disease.

Coronary artery disease (CAD). “For chronic coronary syndrome, a cardiac workup is recommended only for patients undergoing intermediate risk or high-risk noncardiac surgery.”

“Stress imaging should be considered before any high risk, noncardiac surgery in asymptomatic patients with poor functional capacity and prior PCI or coronary artery bypass graft (new recommendation, class IIa).”

Mitral valve regurgitation. For patients undergoing scheduled noncardiac surgery, who remain symptomatic despite guideline-directed medical treatment for mitral valve regurgitation (including resynchronization and myocardial revascularization), consider a valve intervention – either transcatheter or surgical – before noncardiac surgery in eligible patients with acceptable procedural risk (new recommendation).

Cardiac implantable electronic devices (CIED). For high-risk patients with CIEDs undergoing noncardiac surgery with high probability of electromagnetic interference, a CIED checkup and necessary reprogramming immediately before the procedure should be considered (new recommendation).

Arrhythmias. “I want only to stress,” Dr. Mehilli said, “in patients with atrial fibrillation with acute or worsening hemodynamic instability undergoing noncardiac surgery, an emergency electrical cardioversion is recommended (class I).”

Peripheral artery disease (PAD) and abdominal aortic aneurysm. For these patients “we do not recommend a routine referral for a cardiac workup. But we recommend it for patients with poor functional capacity or with significant risk factors or symptoms (new recommendations).”

Chronic arterial hypertension. “We have modified the recommendation, recommending avoidance of large perioperative fluctuations in blood pressure, and we do not recommend deferring noncardiac surgery in patients with stage 1 or 2 hypertension,” she said.
 

Postoperative cardiovascular complications

The most frequent postoperative cardiovascular complication is PMI, Dr. Mehilli noted.

“In the BASEL-PMI registry, the incidence of this complication around intermediate or high-risk noncardiac surgery was up to 15% among patients older than 65 years or with a history of CAD or PAD, which makes this kind of complication really important to prevent, to assess, and to know how to treat.”

“It is recommended to have a high awareness for perioperative cardiovascular complications, combined with surveillance for PMI in patients undergoing intermediate- or high-risk noncardiac surgery” based on serial measurements of high-sensitivity cardiac troponin.

The guidelines define PMI as “an increase in the delta of high-sensitivity troponin more than the upper level of normal,” Dr. Mehilli said. “It’s different from the one used in a rule-in algorithm for non-STEMI acute coronary syndrome.”

Postoperative atrial fibrillation (AFib) is observed in 2%-30% of noncardiac surgery patients in different registries, particularly in patients undergoing intermediate or high-risk noncardiac surgery, she noted.

“We propose an algorithm on how to prevent and treat this complication. I want to highlight that in patients with hemodynamic unstable postoperative AF[ib], an emergency cardioversion is indicated. For the others, a rate control with the target heart rate of less than 110 beats per minute is indicated.”

In patients with postoperative AFib, long-term oral anticoagulation therapy should be considered in all patients at risk for stroke, considering the anticipated net clinical benefit of oral anticoagulation therapy as well as informed patient preference (new recommendations).

Routine use of beta-blockers to prevent postoperative AFib in patients undergoing noncardiac surgery is not recommended.

The document also covers the management of patients with kidney disease, diabetes, cancer, obesity, and COVID-19. In general, elective noncardiac surgery should be postponed after a patient has COVID-19, until he or she recovers completely, and coexisting conditions are optimized.

The guidelines are available from the ESC website in several formats: pocket guidelines, pocket guidelines smartphone app, guidelines slide set, essential messages, and the European Heart Journal article.
 

Noncardiac surgery risk categories

The guideline includes a table that classifies noncardiac surgeries into three groups, based on the associated 30-day risk of death, MI, or stroke:

• Low (< 1%): breast, dental, eye, thyroid, and minor gynecologic, orthopedic, and urologic surgery.
• Intermediate (1%-5%): carotid surgery, endovascular aortic aneurysm repair, gallbladder surgery, head or neck surgery, hernia repair, peripheral arterial angioplasty, renal transplant, major gynecologic, orthopedic, or neurologic (hip or spine) surgery, or urologic surgery
• High (> 5%): aortic and major vascular surgery (including aortic aneurysm), bladder removal (usually as a result of cancer), limb amputation, lung or liver transplant, pancreatic surgery, or perforated bowel repair.

The guidelines were endorsed by the European Society of Anaesthesiology and Intensive Care. The guideline authors reported numerous disclosures.

The European Society of Cardiology guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery have seen extensive revision since the 2014 version.

They still have the same aim – to prevent surgery-related bleeding complications, perioperative myocardial infarction/injury (PMI), stent thrombosis, acute heart failure, arrhythmias, pulmonary embolism, ischemic stroke, and cardiovascular (CV) death.

Cochairpersons Sigrun Halvorsen, MD, PhD, and Julinda Mehilli, MD, presented highlights from the guidelines at the annual congress of the European Society of Cardiology and the document was simultaneously published online in the European Heart Journal.

The document classifies noncardiac surgery into three levels of 30-day risk of CV death, MI, or stroke. Low (< 1%) risk includes eye or thyroid surgery; intermediate (1%-5%) risk includes knee or hip replacement or renal transplant; and high (> 5%) risk includes aortic aneurysm, lung transplant, or pancreatic or bladder cancer surgery (see more examples below).

It classifies patients as low risk if they are younger than 65 without CV disease or CV risk factors (smoking, hypertension, diabetes, dyslipidemia, family history); intermediate risk if they are 65 or older or have CV risk factors; and high risk if they have CVD.  

In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:

Practice has gone back and forth on whether atrial fibrillation (AFib) should be considered in the preoperative cardiovascular risk (CV) evaluation of patients slated for noncardiac surgery, and the Revised Cardiac Risk Index (RCRI), currently widely used as an assessment tool, doesn’t include the arrhythmia.

But consideration of preexisting AFib along with the RCRI predicted 30-day mortality more sharply than the RCRI alone in an analysis of data covering several million patients slated for such procedures.

ECG_Electrocardiogram_web.jpg

• 1.31 (95% CI, 1.30-1.33) for heart failure
• 1.40 (95% CI, 1.37-1.43) for stroke
• 1.59 (95% CI, 1.43-1.75) for systemic embolism
• 1.14 (95% CI, 1.13-1.16) for major bleeding  
• 0.81 (95% CI, 0.79-0.82) for MI

Those with preexisting AFib also had longer hospitalizations at a median 5 days, compared with 4 days for those without such AFib (P < .001).

The study has the limitations of most any retrospective cohort analysis. Other limitations, the report notes, include lack of information on any antiarrhythmic meds given during hospitalization or type of AFib.

For example, AFib that is permanent – compared with paroxysmal or persistent – may be associated with more atrial fibrosis, greater atrial dilatation, “and probably higher pressures inside the heart,” Dr. Mentias observed.

“That’s not always the case, but that’s the notion. So presumably people with persistent or permanent atrial fib would have more advanced heart disease, and that could imply more risk. But we did not have that kind of data.”

Dr. Mentias and Dr. Prasada report no relevant financial relationships; disclosures for the other authors are in the report. Dr. Curtis discloses serving on advisory boards for Abbott, Janssen Pharmaceuticals, Sanofi, and Milestone Pharmaceuticals; receiving honoraria for speaking from Medtronic and Zoll; and serving on a data-monitoring board for Medtronic. Dr. Korada reports he has no relevant financial relationships.

Knee and shoulder pain are common complaints for patients in the primary care office.

But identifying the source of the pain can be complicated,

and an accurate diagnosis of the underlying cause of discomfort is key to appropriate management – whether that involves simple home care options of ice and rest or a recommendation for a follow-up with a specialist.

Speaking at the annual meeting of the American College of Physicians, Greg Nakamoto, MD, department of orthopedics, Virginia Mason Medical Center, Seattle, discussed common knee and shoulder problems that patients often present with in the primary care setting, and offered tips on diagnosis and appropriate management.

The most common conditions causing knee pain are osteoarthritis and meniscal tears. “The differential for knee pain is broad,” Dr. Nakamoto said. “You have to have a way to divide it down, such as if it’s acute or chronic.”

The initial workup has several key components. The first steps: Determine the location of the pain – anterior, medial, lateral, posterior – and then whether it stems from an injury or is atraumatic.

“If you have to ask one question – ask where it hurts,” he said. “And is it from an injury or just wear and tear? That helps me when deciding if surgery is needed.”

Pain in the knee generally localizes well to the site of pathology, and knee pain of acute traumatic onset requires more scrutiny for problems best treated with early surgery. “This also helps establish whether radiographic findings are due to injury or degeneration,” Dr. Nakamoto said. “The presence of swelling guides the need for anti-inflammatories or cortisone.”

Palpating for tenderness along the joint line is important, as is palpating above and below the joint line, Dr. Nakamoto said.

“Tenderness limited to the joint line, combined with a meniscal exam maneuver that reproduces joint-line pain, is suggestive of pain from meniscal pathology,” he said.

Imaging is an important component of evaluating knee symptoms, and the question often arises as to when to order an MRI.

Dr. Nakamoto offered the following scenario: If significant osteoarthritis is evident on weight-bearing x-ray, treat the patient for the condition. However, if little or no osteoarthritis appears on x-ray, and if the onset of symptoms was traumatic and both patient history and physical examination suggest a meniscal tear, order an MRI.

An early MRI also is needed if the patient has had either atraumatic or traumatic onset of symptoms and their history and physical exams are suspicious for a mechanically locked or locking meniscus. For suspicion of a ruptured quadriceps or patellar tendon or a stress fracture, an MRI is needed urgently.

An MRI would be ordered later if the patient’s symptoms have not improved significantly after 3 months of conservative management.

Dr. Nakamoto stressed how common undiagnosed meniscus tears are in the general population. A third of men aged 50-59 years and nearly 20% of women in that age group have a tear, he said. “That number goes up to 56% and 51% in men and women aged 70-90 years, and 61% of these tears were in patients who were asymptomatic in the last month.”

In the setting of osteoarthritis, 76% of asymptomatic patients had a meniscus tear, and 91% of patients with symptomatic osteoarthritis had a meniscus tear, he added.

Treating knee pain

Treatment will vary depending on the underlying etiology of pain. For a possible meniscus tear, the recommendation is for a conservative intervention with ice, ibuprofen, knee immobilizer, and crutches, with a follow-up appointment in a week.

Three types of injections also can help:

• Cortisone for osteoarthritis or meniscus tears, swelling, and inflammation, and prophylaxis against inflammation.
• Viscosupplementation (intra‐articular hyaluronic acid) for chronic, baseline osteoarthritis symptoms.
• Regenerative therapies (platelet-rich plasma, stem cells, etc.) are used primarily for osteoarthritis (these do not regrow cartilage, but some patients report decreased pain).

The data on injections are mixed, Dr. Nakamoto said. For example, the results of a 2015 Cochrane review on cortisone injections for osteoarthritis reported that the benefits were small to moderate at 4‐6 weeks, and small to none at 13 weeks.  

“There is a lot of controversy for viscosupplementation despite all of the data on it,” he said. “But the recommendations from professional organizations are mixed.”

He noted that he has been using viscosupplementation since the 1990s, and some patients do benefit from it.

Shoulder pain

The most common causes of shoulder pain are adhesive capsulitis, rotator cuff tears and tendinopathy, and impingement.

As with knee pain, the same assessment routine largely applies.

First, pinpoint the location: Is the trouble spot the lateral shoulder and upper arm, the trapezial ridge, or the shoulder blade?

Next, assess pain on movement: Does the patient experience discomfort reaching overhead or behind the back, or moving at the glenohumeral joint/capsule and engaging the rotator cuff? Check for stiffness, weakness, and decreased range of motion in the rotator cuff.

Determine if the cause of the pain is traumatic or atraumatic and stems from an acute injury versus degeneration or overuse.

As with the knee, imaging is a major component of the assessment and typically involves the use of x-ray. An MRI may be required for evaluating full- and partial-thickness tears and when contemplating surgery.

MRI also is necessary for evaluating cases of acute, traumatic shoulder injury, and patients exhibiting disability suggestive of a rotator cuff tear in an otherwise healthy tendon.

Some pain can be treated with cortisone injections or regenerative therapies, which generally are given at the acromioclavicular or glenohumeral joints or in the subacromial space. A 2005 meta-analysis found that subacromial injections of corticosteroids are effective for improvement for rotator cuff tendinitis up to a 9‐month period.

Surgery may be warranted in some cases, Dr. Nakamoto said. These include adhesive capsulitis, rotator cuff tear, acute traumatic injury in an otherwise healthy tendon, and chronic (or acute-on-chronic) tears in a degenerative tendon following a trial of conservative therapy.

Knee and shoulder pain are common complaints for patients in the primary care office.

But identifying the source of the pain can be complicated,

and an accurate diagnosis of the underlying cause of discomfort is key to appropriate management – whether that involves simple home care options of ice and rest or a recommendation for a follow-up with a specialist.

The antifibrinolytic tranexamic acid (TXA) reduced serious bleeding without a significant effect on major vascular outcomes in patients undergoing noncardiac surgery at risk for these complications in the POISE-3 trial.

TXA cut the primary efficacy outcome of life-threatening, major, and critical organ bleeding at 30 days by 24% compared with placebo (9.1% vs. 11.7%; hazard ratio [HR], 0.76; P < .0001).

The primary safety outcome of myocardial injury after noncardiac surgery (MINS), nonhemorrhagic stroke, peripheral arterial thrombosis, and symptomatic proximal venous thromboembolism (VTE) at 30 days occurred in 14.2% vs.. 13.9% of patients, respectively (HR, 1.023). This failed, however, to meet the study›s threshold to prove TXA noninferior to placebo (one-sided P = .044).

There was no increased risk for death or stroke with TXA, according to results published April 2 in the New England Journal of Medicine.

Principal investigator P.J. Devereaux, MD, PhD, Population Health Research Institute and McMaster University, Hamilton, Ontario, Canada, pointed out that there is only a 4.4% probability that the composite vascular outcome hazard ratio was above the noninferiority margin and that just 10 events separated the two groups (649 vs.. 639).

“Healthcare providers and patients will have to weigh a clear beneficial reduction in the composite bleeding outcome, which is an absolute difference of 2.7%, a result that was highly statistically significant, versus a low probability of a small increase in risk of the composite vascular endpoint, with an absolute difference of 0.3%,” a nonsignificant result, Dr. Devereaux said during the formal presentation of the results at the hybrid annual scientific sessions of the American College of Cardiology.

The findings, he said, should also be put in the context that 300 million adults have a major surgery each year worldwide and most don’t receive TXA. At the same time, there’s an annual global shortage of 30 million blood product units, and surgical bleeding accounts for up to 40% of all transfusions.

“POISE-3 identifies that use of TXA could avoid upwards of 8 million bleeding events resulting in transfusion on an annual basis, indicating potential for large public health and clinical benefit if TXA become standard practice in noncardiac surgery,” Dr. Devereaux said during the late-breaking trial session.

TXA is indicated for heavy menstrual bleeding and hemophilia and has been used in cardiac surgery, but it is increasingly being used in noncardiac surgeries. As previously reported, POISE showed that the beta-blocker metoprolol lowered the risk for myocardial infarction (MI) but increased the risk for severe stroke and overall death, whereas in POISE-2, perioperative low-dose aspirin lowered the risk for MI but was linked to more major bleeding.

The cumulative data have not shown an increased risk for thrombotic events in other settings, Dr. Devereaux told this news organization.

“I’m a cardiologist, and I think that we’ve been guilty at times of always only focusing on the thrombotic side of the equation and ignoring that bleeding is a very important aspect of the circulatory system,” he said. “And I think this shows for the first time clear unequivocal evidence that there’s a cheap, very encouraging, safe way to prevent this.”

“An important point is that if you can give tranexamic acid and prevent bleeding in your cardiac patients having noncardiac surgery, then you can prevent the delay of reinitiating their anticoagulants and their antiplatelets after surgery and getting them back on the medications that are important for them to prevent their cardiovascular event,” Dr. Devereaux added.

Discussant Michael J. Mack, MD, commented that TXA, widely used in cardiac surgery, is an old, inexpensive drug that “should be more widely used in noncardiac surgery.” Dr. Mack, from Baylor Scott & White Health, Dallas, added that he would limit it to major noncardiac surgery.

International trial

PeriOperative ISchemic Evaluation-3 (POISE-3) investigators at 114 hospitals in 22 countries (including countries in North and South America, Europe, and Africa; Russia; India; and Australia) randomly assigned 9,535 patients, aged 45 years or older, with or at risk for cardiovascular and bleeding complications to receive a TXA 1-g intravenous bolus or placebo at the start and end of inpatient noncardiac surgery.

Patients taking at least one long-term antihypertensive medication were also randomly assigned to a perioperative hypotension- or hypertension-avoidance strategy, which differ in the use of antihypertensives on the morning of surgery and the first 2 days after surgery, and in the target mean arterial pressure during surgery. Results from these cohorts will be presented in a separate session on April 4.

The study had planned to enroll 10,000 patients but was stopped early by the steering committee because of financial constraints resulting from slow enrollment during the pandemic. The decision was made without knowledge of the trial results but with knowledge that aggregate composite bleeding and vascular outcomes were higher than originally estimated, Dr. Devereaux noted.

Among all participants, the mean age was 70 years, 56% were male, almost a third had coronary artery disease, 15% had peripheral artery disease, and 8% had a prior stroke. About 80% were undergoing major surgery. Adherence to the study medications was 96.3% in both groups.

[embed:render:related:node:152179]

Secondary bleeding outcomes were lower in the TXA and placebo groups, including bleeding independently associated with mortality after surgery (8.7% vs. 11.3%), life-threatening bleeding (1.6% vs. 1.7%), major bleeding (7.6% vs. 10.4%), and critical organ bleeding (0.3% vs. 0.4%).

Importantly, the TXA group had significantly lower rates of International Society on Thrombosis and Haemostasis major bleeding (6.6% vs. 8.7%; P = .0001) and the need for transfusion of 1 or more units of packed red blood cells (9.4% vs. 12.0%; P <.0001), Dr. Devereaux noted.

In terms of secondary vascular outcomes, there were no significant differences between the TXA and placebo groups in rates of MINS (12.8% vs. 12.6%), MINS not fulfilling definition of MI (both 11.5%), MI (1.4% vs. 1.1%), and the net risk-benefit outcome (a composite of vascular death and nonfatal life-threatening, major, or critical organ bleeding, MINS, stroke, peripheral arterial thrombosis, and symptomatic proximal VTE; 20.7% vs. 21.9%).

The two groups had similar rates of all-cause (1.1% vs. 1.2%) and vascular (0.5% vs. 0.6%) mortality.

There also were no significant differences in other tertiary outcomes, such as acute kidney injury (14.1% vs. 13.7%), rehospitalization for vascular reasons (1.8% vs. 1.6%), or seizures (0.2% vs. <0.1%). The latter has been a concern, with the risk reported to increase with higher doses.

Subgroup analyses

Preplanned subgroup analyses showed a benefit for TXA over placebo for the primary efficacy outcome in orthopedic and nonorthopedic surgery and in patients with hemoglobin level below 120 g/L or 120 g/L or higher, with an estimated glomerular filtration rate less than 45 mL/min/1.73 m ²  or 45 mL/min/1.73 m ²  or higher, or with an N-terminal pro– B-type natriuretic peptide level below 200 ng/L or 200 ng/L or higher.

For the primary safety outcome, the benefit favored placebo but the interaction was not statistically significant for any of the four subgroups.

A post hoc subgroup analysis also showed similar results across the major categories of surgery, including general, vascular, urologic, and gynecologic, Dr. Devereaux told this news organization.

Although TXA is commonly used in orthopedic procedures, Dr. Devereaux noted, in other types of surgeries, “it’s not used at all.” But because TXA “is so cheap, and we can apply it to a broad population, even at an economic level it looks like it’s a winner to give to almost all patients having noncardiac surgery.”

The team also recently published a risk prediction tool that can help estimate a patient’s baseline risk for bleeding.

“So just using a model, which will bring together the patient’s type of surgery and their risk factors, you can look to see, okay, this is enough risk of bleeding, I’m just going to give tranexamic acid,” he said. “We will also be doing economic analyses because blood is also not cheap.”

The study was funded by the Canadian Institutes of Health Research, National Health and Medical Research Council (Australia), and the Research Grant Council (Hong Kong). Dr. Devereaux reports research/research grants from Abbott Diagnostics, Philips Healthcare, Roche Diagnostics, and Siemens. Dr. Mack reports receiving research grants from Abbott Vascular, Edwards Lifesciences, and Medtronic.

Preplanned subgroup analyses showed a benefit for TXA over placebo for the primary efficacy outcome in orthopedic and nonorthopedic surgery and in patients with hemoglobin level below 120 g/L or 120 g/L or higher, with an estimated glomerular filtration rate less than 45 mL/min/1.73 m ²  or 45 mL/min/1.73 m ²  or higher, or with an N-terminal pro– B-type natriuretic peptide level below 200 ng/L or 200 ng/L or higher.

For the primary safety outcome, the benefit favored placebo but the interaction was not statistically significant for any of the four subgroups.

A post hoc subgroup analysis also showed similar results across the major categories of surgery, including general, vascular, urologic, and gynecologic, Dr. Devereaux told this news organization.

Although TXA is commonly used in orthopedic procedures, Dr. Devereaux noted, in other types of surgeries, “it’s not used at all.” But because TXA “is so cheap, and we can apply it to a broad population, even at an economic level it looks like it’s a winner to give to almost all patients having noncardiac surgery.”

The team also recently published a risk prediction tool that can help estimate a patient’s baseline risk for bleeding.

“So just using a model, which will bring together the patient’s type of surgery and their risk factors, you can look to see, okay, this is enough risk of bleeding, I’m just going to give tranexamic acid,” he said. “We will also be doing economic analyses because blood is also not cheap.”

The study was funded by the Canadian Institutes of Health Research, National Health and Medical Research Council (Australia), and the Research Grant Council (Hong Kong).

The antifibrinolytic tranexamic acid (TXA) reduced serious bleeding without a significant effect on major vascular outcomes in patients undergoing noncardiac surgery at risk for these complications in the POISE-3 trial.

TXA cut the primary efficacy outcome of life-threatening, major, and critical organ bleeding at 30 days by 24% compared with placebo (9.1% vs. 11.7%; hazard ratio [HR], 0.76; P < .0001).

The primary safety outcome of myocardial injury after noncardiac surgery (MINS), nonhemorrhagic stroke, peripheral arterial thrombosis, and symptomatic proximal venous thromboembolism (VTE) at 30 days occurred in 14.2% vs.. 13.9% of patients, respectively (HR, 1.023). This failed, however, to meet the study›s threshold to prove TXA noninferior to placebo (one-sided P = .044).

There was no increased risk for death or stroke with TXA, according to results published April 2 in the New England Journal of Medicine.

Principal investigator P.J. Devereaux, MD, PhD, Population Health Research Institute and McMaster University, Hamilton, Ontario, Canada, pointed out that there is only a 4.4% probability that the composite vascular outcome hazard ratio was above the noninferiority margin and that just 10 events separated the two groups (649 vs.. 639).

“Healthcare providers and patients will have to weigh a clear beneficial reduction in the composite bleeding outcome, which is an absolute difference of 2.7%, a result that was highly statistically significant, versus a low probability of a small increase in risk of the composite vascular endpoint, with an absolute difference of 0.3%,” a nonsignificant result, Dr. Devereaux said during the formal presentation of the results at the hybrid annual scientific sessions of the American College of Cardiology.

The findings, he said, should also be put in the context that 300 million adults have a major surgery each year worldwide and most don’t receive TXA. At the same time, there’s an annual global shortage of 30 million blood product units, and surgical bleeding accounts for up to 40% of all transfusions.

“POISE-3 identifies that use of TXA could avoid upwards of 8 million bleeding events resulting in transfusion on an annual basis, indicating potential for large public health and clinical benefit if TXA become standard practice in noncardiac surgery,” Dr. Devereaux said during the late-breaking trial session.

TXA is indicated for heavy menstrual bleeding and hemophilia and has been used in cardiac surgery, but it is increasingly being used in noncardiac surgeries. As previously reported, POISE showed that the beta-blocker metoprolol lowered the risk for myocardial infarction (MI) but increased the risk for severe stroke and overall death, whereas in POISE-2, perioperative low-dose aspirin lowered the risk for MI but was linked to more major bleeding.

The cumulative data have not shown an increased risk for thrombotic events in other settings, Dr. Devereaux told this news organization.

“I’m a cardiologist, and I think that we’ve been guilty at times of always only focusing on the thrombotic side of the equation and ignoring that bleeding is a very important aspect of the circulatory system,” he said. “And I think this shows for the first time clear unequivocal evidence that there’s a cheap, very encouraging, safe way to prevent this.”

“An important point is that if you can give tranexamic acid and prevent bleeding in your cardiac patients having noncardiac surgery, then you can prevent the delay of reinitiating their anticoagulants and their antiplatelets after surgery and getting them back on the medications that are important for them to prevent their cardiovascular event,” Dr. Devereaux added.

Discussant Michael J. Mack, MD, commented that TXA, widely used in cardiac surgery, is an old, inexpensive drug that “should be more widely used in noncardiac surgery.” Dr. Mack, from Baylor Scott & White Health, Dallas, added that he would limit it to major noncardiac surgery.

International trial

PeriOperative ISchemic Evaluation-3 (POISE-3) investigators at 114 hospitals in 22 countries (including countries in North and South America, Europe, and Africa; Russia; India; and Australia) randomly assigned 9,535 patients, aged 45 years or older, with or at risk for cardiovascular and bleeding complications to receive a TXA 1-g intravenous bolus or placebo at the start and end of inpatient noncardiac surgery.

Patients taking at least one long-term antihypertensive medication were also randomly assigned to a perioperative hypotension- or hypertension-avoidance strategy, which differ in the use of antihypertensives on the morning of surgery and the first 2 days after surgery, and in the target mean arterial pressure during surgery. Results from these cohorts will be presented in a separate session on April 4.

The study had planned to enroll 10,000 patients but was stopped early by the steering committee because of financial constraints resulting from slow enrollment during the pandemic. The decision was made without knowledge of the trial results but with knowledge that aggregate composite bleeding and vascular outcomes were higher than originally estimated, Dr. Devereaux noted.

Among all participants, the mean age was 70 years, 56% were male, almost a third had coronary artery disease, 15% had peripheral artery disease, and 8% had a prior stroke. About 80% were undergoing major surgery. Adherence to the study medications was 96.3% in both groups.

[embed:render:related:node:152179]

Secondary bleeding outcomes were lower in the TXA and placebo groups, including bleeding independently associated with mortality after surgery (8.7% vs. 11.3%), life-threatening bleeding (1.6% vs. 1.7%), major bleeding (7.6% vs. 10.4%), and critical organ bleeding (0.3% vs. 0.4%).

Importantly, the TXA group had significantly lower rates of International Society on Thrombosis and Haemostasis major bleeding (6.6% vs. 8.7%; P = .0001) and the need for transfusion of 1 or more units of packed red blood cells (9.4% vs. 12.0%; P <.0001), Dr. Devereaux noted.

In terms of secondary vascular outcomes, there were no significant differences between the TXA and placebo groups in rates of MINS (12.8% vs. 12.6%), MINS not fulfilling definition of MI (both 11.5%), MI (1.4% vs. 1.1%), and the net risk-benefit outcome (a composite of vascular death and nonfatal life-threatening, major, or critical organ bleeding, MINS, stroke, peripheral arterial thrombosis, and symptomatic proximal VTE; 20.7% vs. 21.9%).

The two groups had similar rates of all-cause (1.1% vs. 1.2%) and vascular (0.5% vs. 0.6%) mortality.

There also were no significant differences in other tertiary outcomes, such as acute kidney injury (14.1% vs. 13.7%), rehospitalization for vascular reasons (1.8% vs. 1.6%), or seizures (0.2% vs. <0.1%). The latter has been a concern, with the risk reported to increase with higher doses.

Proprietary templating software to guide the positioning of total shoulder arthroplasty (TSA) generate very different measures for inclination and version, according to a study that compared four programs and reported in an abstract scheduled for release at the annual meeting of the American Academy of Orthopaedic Surgeons. The meeting was canceled due to COVID-19.

“It is not a question of one software being better than another. They are just different, and they are device specific,” reported Brent B. Wiesel, MD, chief of the shoulder service at the MedStar Georgetown Orthopaedic Institute, Washington.

The variations were substantial and clinically relevant, suggesting that surgeons need to be aware of these differences when switching between the devices, according to Dr. Wiesel. He said that there is no gold standard for positioning total shoulder arthroplasty, which prevents any conclusion about the superiority of one over the other.

In this study, 76 CT scans obtained from shoulders of patients with glenohumeral arthritis were analyzed for native glenoid version and inclination by the ArthrexVIP, Tornier BluePrint, Stryker TrueSight, and ExactechGPS software programs. Dr. Wiesel explained that these are among the most commonly used programs, but there are others.

After extracting the recommended version and inclination measures from each software program, agreement between measures was calculated with an analysis of variance (ANOVA) test. The variance across programs was highly significant for both native glenoid version and inclination (P < .001).

Inter-rater reliability of the software outputs analyzed with Krippendorff’s alpha, for which a value of 1.0 signals perfect agreement and a value of 0 signals complete disagreement, reinforced the discord. For the 76 scans, the values for version and inclination were 0.272 and 0.303, respectively. Both are extremely low.

“The suggested threshold for high reliability is a value of 0.8 or greater,” said Dr. Wiesel, who was contacted about these data after the AAOS annual meeting was canceled. “The lowest acceptable limit for reliability is 0.667 or greater.”

There was disagreement across all programs. The only agreement to reach an acceptable Krippendorff’s alpha was generated by the Tornier BluePrint and Stryker TrueSight programs. These programs modestly agreed on version (0.706 on the Krippendorff’s alpha), but agreement on inclination was below the acceptable threshold.

“In other words, if you take the same scan from the same patient, you will get different angles from these different templating software programs,” Dr. Wiesel said.

There are several messages from these data, according to Dr. Wiesel. In addition to demonstrating the programs generate outputs that do not agree, he suggested that the values provided by the programs should not be considered absolute. Rather, the software values should be interpreted in the context of the individual patient.

“It is easy to get lazy, but it is important to remember that the software is a tool rather than something that will do the procedure for you,” Dr. Wiesel said. He reported that when the software guidance is not consistent with his own experience, he proceeds cautiously.

“On several occasions when the software has provided measures that are not consistent with my own perception, I have not been happy when I went with the software,” he said. “So typically I go with my gut when there is a discrepancy, and the data from this study supports that.”

Because of the difficulty in creating a gold standard for templating when there are multiple variables that influence optimal positioning of components, Dr. Wiesel suggested that “crowd thinking” might eventually determine the values that produce the best results. By crowd thinking, he was referring to Big Data analysis, collating data from a large number of cases performed by a large number of surgeons.

“All of these software programs provide reasonable guidance, but each has different advantages and disadvantages, and it is important to be aware that they are different,” Dr. Wiesel reported.

There are differences in the templating software, and they should be taken into consideration, according to another expert who has looked at this issue. Senior author of a randomized trial evaluating planning strategies for total shoulder arthroplasty ( J Bone Joint Surg AM. 2019:101;446-57), Eric T. Ricchetti, MD, an orthopedic surgeon and director of the shoulder center at the Cleveland Clinic, offered a similar perspective on templating.

“I agree that surgeons should be familiar with the differences that exist in templating software,” Dr. Ricchetti said. Basing his remarks on his own experience and reiterating the conclusion of the AAOS study, he added, “the methods that are used to identify the bone anatomy of the shoulder can vary across software programs, potentially resulting in differences in subsequent measures of glenoid pathology, such as version and inclination, that may impact surgical decision making.”

Dr. Wiesel reports no potential conflicts of interest.

A new study has found that a simple screening tool can identify patients at risk of postoperative delirium (POD) after orthopedic surgery, and a prevention program can help improve staff education and outcomes.

elderly wheelchair doctor_web.jpg

“In an aging society, it is very important to develop and implement a strategy for POD prevention to ensure that aging patients are treated as safely and effectively as possible,” wrote Jung-Yeon Choi of Seoul (South Korea) National University Bundang Hospital and coauthors. The study was published in BMC Geriatrics.

To determine how to better identify and treat high-risk patients for POD after orthopedic surgery, the researchers led a retrospective cohort study that included an intervention group of participants who were aged at least 65 years (n = 275) and a control group from a year prior (n = 274). Patients in the intervention group had their risk of delirium assessed and categorized using a simple screening tool, and those deemed at risk were entered into a multicomponent delirium prevention program.

Of the 275 patients in the intervention group, 144 required screening for delirium. Ninety-nine were classified as low risk, 29 were classified as high risk, and 16 missed the screening. Fifty-three additional patients were classified as high risk because they were aged 80 years or older. During the study, 17 participants experienced POD, 16 of whom were classified as high risk. In regard to estimating POD risk, the sensitivity and specificity of the delirium screening tool were 94.1% and 72.7%, respectively. Incidence rates of POD were 10.2% in the control group and 6.2% in the intervention group.

The authors noted their study’s limitations, including its design as a retrospective review of medical records rather than a prospective randomized controlled trial. In addition, because it was conducted in just one teaching hospital, they deemed it “not possible to determine the generalizability and long-term effect of our findings.”

The authors reported no conflicts of interest.

ABSTRACT

Fragility fractures are estimated to affect 3 million people annually in the United States. As they are associated with a significant mortality rate, the prevention of these fractures should be a priority for orthopedists. At-risk patients include the elderly and those with thyroid disease, diabetes, hypertension, and heart disease. Osteoporosis is diagnosed by the presence of a fragility fracture or by dual-energy x-ray absorptiometry (DXA) in the absence of a fragility fracture. In 2011, the United States Preventive Services Task Force (USPSTF) recommended that all women ≥65 years should be screened for osteoporosis by DXA. Women <65 years with a 10-year fracture risk =/> than that of a 65-year-old white woman should also be screened for osteoporosis. Lifestyle changes, such as calcium and vitamin D supplementation, exercise, and smoking cessation, are non-pharmacologic treatment options. The National Osteoporosis Foundation recommends treating osteoporosis with pharmacotherapy in patients with a high risk for fracture (T score <–2.5) or history of fragility fracture. Understanding risk factors and eliminating medications known to cause decreased BMD are vital to prevention and will be necessary to limit these fractures and their associated expenses in the future.

Fragility fractures are caused by falls from standing height or repetitive physiological loads.¹ With the growing aging population in the United States, it is estimated that 3 million people will be affected by fragility fractures yearly.² In the setting of osseous insufficiency, fractures that are typically associated with high-energy trauma are encountered in patients who simply trip over a parking lot curb or fall off their bike. After surgery, the severe disruption of patients’ lives continues with a prolonged rehabilitation period.

ABSTRACT

Fragility fractures are estimated to affect 3 million people annually in the United States. As they are associated with a significant mortality rate, the prevention of these fractures should be a priority for orthopedists. At-risk patients include the elderly and those with thyroid disease, diabetes, hypertension, and heart disease. Osteoporosis is diagnosed by the presence of a fragility fracture or by dual-energy x-ray absorptiometry (DXA) in the absence of a fragility fracture. In 2011, the United States Preventive Services Task Force (USPSTF) recommended that all women ≥65 years should be screened for osteoporosis by DXA. Women <65 years with a 10-year fracture risk =/> than that of a 65-year-old white woman should also be screened for osteoporosis. Lifestyle changes, such as calcium and vitamin D supplementation, exercise, and smoking cessation, are non-pharmacologic treatment options. The National Osteoporosis Foundation recommends treating osteoporosis with pharmacotherapy in patients with a high risk for fracture (T score <–2.5) or history of fragility fracture. Understanding risk factors and eliminating medications known to cause decreased BMD are vital to prevention and will be necessary to limit these fractures and their associated expenses in the future.

ABSTRACT

Total shoulder arthroplasty (TSA) has proved a cost-effective, reproducible procedure for multiple shoulder pathologies. As utilization of TSA continues to grow, it is important to investigate procedure diversity, training, and other characteristics of surgeons performing TSA. To identify surgeons performing TSA in the Medicare population, the Medicare Provider Utilization and Payment Databases from 2012 through 2014 were used. This dataset includes any provider who bills Medicare >10 times with a single billing code. A web-based search was performed for each physician performing >10 TSA in all years of the study to identify their surgical training characteristics. Between 2012 and 2014, 1374 surgeons (39 females [2.8%]) performed >10 TSA in Medicare patients in at least 1 year (71,973 TSA). Only 44.3% (609/1374) of surgeons met this threshold for all 3 years (55,538 TSA). Of these 609 surgeons, 191 (31.3%) were shoulder and elbow fellowship trained (21,444 TSA). Shoulder and elbow fellowship-trained surgeons were at earlier points in their careers and practiced in large referral-based centers with other surgeons performing TSA. In addition to TSA, surgeons performed other non-arthroplasty shoulder procedures (80.2% of surgeons), total knee arthroplasty (46.3%), repairs of traumatic injuries (29.8%), total hip arthroplasty (27.8%), non-arthroplasty knee surgeries (27.2%), elbow procedures (19.6%), and hand surgery (15.4%) during the study period. With less than one-third of TSA performed by shoulder and elbow fellowship-trained surgeons with consistent moderate-volume practices, the impact of consistent high-volume practices and targeted fellowship training on quality must be determined.

With the adoption of reverse shoulder arthroplasty, utilization of total shoulder arthroplasty (TSA) has increased substantially over the last decade.^1–3 Such increases are likely secondary to an aging population, increased comfort with the procedure, and the adoption of broadened indications for reverse shoulder arthroplasty, especially in the setting of proximal humerus fractures in the elderly.^4–7 Between 2012 and 2014 alone, the number of surgeons performing >10 TSA in Medicare patients annually increased by 28.6% (824 to 1060 surgeons) providing a 26.6% (20,824-26,365 procedures) increase in national volume in the Medicare population.2 With this boom in utilization, scrutiny of this now routine procedure and those performing it is necessary.

Prior reviews have demonstrated a strong link between surgeon and hospital TSA volume and outcomes of the procedure.^8–10 Somerson and colleagues¹¹ investigated fellowship training among surgeons performing TSA in 2012 and found that only 28% had completed a shoulder and elbow fellowship. In addition to prior analyses2, ¹², Somerson and colleagues confirmed a persistent geographic variation in utilization of TSA.¹¹ In conjunction with the evolution of shoulder arthroplasty, dedicated shoulder and elbow fellowship training has expanded. With a shift toward specialization in care, nearly 90% of orthopedic surgery residents plan to pursue shoulder and elbow fellowships, comprising 4.6% of (42/897) of available positions.¹³  

What remains unknown is the specialization of surgeons performing TSA, the regularity of their arthroplasty volume, and trends in TSA specialization over time. Therefore, this study aims to (a) identify surgeons performing shoulder arthroplasty and cohort changes over time, (b) determine the case profile of surgeons consistently performing shoulder arthroplasty, and (c) establish the characteristics of shoulder arthroplasty surgeons with a specific focus on fellowship training. 

METHODS

Prior to collecting surgeon-specific data, we identified surgeons performing TSA through the Centers for Medicare and Medicaid Services’ public release of “Medicare Provider Utilization and Payment Data: Physician and Other Supplier.”¹⁴ Datasets from 2012, 2013, and 2014 were used to identify all surgeons performing >10 TSAs (Current Procedural Terminology [CPT] Code 23472) during at least 1 of those years. This dataset provides the name, identification number, address, and all billing (by volume) for each unique CPT code submitted ≥10 times in a calendar year.

Once the cohort of surgeons had been generated, the number of surgeons consistently performing TSA year-over-year was determined. This allowed for an analysis of the consistency with which surgeons are performing moderate- to high-volume TSA. To form a case profile of surgeons performing TSA and observe how this shifted over time, a count and a description of each CPT code submitted by each surgeon was identified. To maintain patient privacy, only those claims made >10 times are reported for a provider (both physicians and physician-extenders are included in this dataset). First, all CPT codes were reviewed and tagged as surgical or non-surgical events. Then, every procedural CPT code identified was reviewed and categorized based upon anatomic location and procedure (eg, total knee arthroplasty [TKA]). It is important to note that all claims in this dataset are limited to those patients participating in Medicare’s fee-for-service program. 

Specialization was defined as the number of categorized procedures as a percentage of all procedures performed on Medicare patients. The trends for national, regional, and individual specialization of TSA, arthroplasty (major joint), and shoulder procedures were determined.

To investigate the characteristics of surgeons consistently performing TSA, all surgeons performing a minimum of 11 TSA in Medicare fee-for-service beneficiaries in all years between 2012 and 2014 were identified. Such surgeons were defined as consistent TSA surgeons. Investigation of this cohort included a web-based search of their self-reported post-graduate fellowship training and year of graduation from medical school. Using these data, the percentage of surgeons performing TSA who underwent formal shoulder and elbow training was determined. In addition, the impact of fellowship training on shoulder specialization and practice location was determined. Surgeons who had completed multiple fellowships were categorized under all of them. As such, there may be some duplication of surgeons in the comparisons. In addition, other potential characteristics of shoulder and elbow fellowship-trained surgeons were investigated: number of regional shoulder surgeons, urban area, total number of Medicare beneficiaries, average reimbursement for TSA, ethnicity of Medicare beneficiaries, and percentage of Medicare patients eligible for Medicaid. Geographic regions were defined by the Dartmouth Atlas and assigned by hospital referral region.¹⁵ These defined regions were used to assess the beneficiaries (number and characteristics) that individual surgeons were likely serving. The United States Census Bureau characterization of zip code-based regions as urban areas (population >50,000), urban clusters (2500 to 50,000), and rural region (<2500) was used to categorize practice location.¹⁶ 

Descriptive statistics were used initially to report these findings. To analyze predictors of utilization and specialization, comparative statistics were undertaken. For comparison of binomial variables between groups, a χ2analysis was utilized. For continuous variables, data normality was assessed. A skewness and kurtosis <2 and 12, respectively, was considered to represent parametric data. For parametric data, the mean was reported; conversely, the median is reported for non-parametric data. To assess continuous variables between groups, a t test or a Wilcoxon rank-sum test was used for parametric and non-parametric distributions, respectively. 

RESULTS

Between 2012 and 2014, 1374 surgeons (39 females [2.8%]) performed >10 TSA in Medicare patients in at least 1 year, for a combined total of 71,973 TSAs (Table 1). In 2012, only 834 surgeons (13 females [1.6%]) performed a minimum of 10 TSA in Medicare patients (21,137 arthroplasties; 25.3 per surgeon). This increased to 1078 surgeons (33 females [3.1%]; P = .04) performing 26,865 TSA (24.92 per surgeon) in 2014. Utilization of non-physician assistants in TSA also increased significantly over this period, with 307 assisting in 6885 TSAs (22.4 per provider) in 2012 and 465 assisting 10,433 TSA (22.4 per provider) in 2014. When all procedures were considered, including those performed at outpatient visits, 1319 physicians (95.9% of cohort) were active in 2012—providing either surgical procedures or outpatient consults to the Medicare population. Yet, only 63.2% performed >10 TSA in Medicare patients. The number of active surgeons performing TSA increased to 79.6% (1078/1353) in 2014 (P < .001).

In addition to TSA, this cohort of surgeons submitted 240 unique CPT codes with case volumes >10 annually over the 3-year study period. Of these, 80.2% (1102/1374) of surgeons performed non-arthroplasty shoulder procedures on Medicare patients, for a combined total of 202,335 procedures over the 3-year study period (Table 2). A significant proportion of these procedures were arthroscopic debridement (60,014 procedures performed by 908 surgeons) and arthroscopic rotator cuff repair (47,089 procedures performed by 809 surgeons). Just under half (49.1%; 674/1374) of surgeons performing TSA also performed TKA during this period (77,873 arthroplasties). Fewer surgeons (27.8%; 382/1374) performed total hip arthroplasty during this period (27,322 arthroplasties). Other procedure types that this group of surgeons routinely performed on Medicare patients were repairs of traumatic injuries (29.8%), non-arthroplasty knee surgeries (27.2%), elbow procedures (19.6%), and hand surgery (15.4%). By case load, non-arthroplasty shoulder procedures consisted of 43% of Medicare volume over the study period (Figure 1). Between 2012 and 2014, the average proportion of Medicare cases that were shoulder arthroplasties increased from 13.8% (21,137/152,862) to 16.7% (26,865/160,851; P = .001). Shoulder arthroplasty constituted 100% of the Medicare surgical case volume for 67 (4.9%; 67/1374) of the surgeons.

Only 44.3% (609/1374) of surgeons performed TSA in a minimum of 11 Medicare patients in all 3 years of the study period (consistent providers of TSA), providing a total of 55,538 TSA (77.2%; 55,538/71,973). When fellowship training was evaluated, 191 (31.4%; 191/609) of these surgeons were shoulder and elbow fellowship trained (21,444 TSA; 38.6%; Table 3). More than one-third (36.6%; 223/609) had completed a sports surgery fellowship (18,899 TSA; 34.0%). Surgeons trained in hand surgery (12.5%; 76/609) and adult reconstruction (5.3%; 32/610) also made contributions to meeting the TSA demand with 6971 (12.6%) and 2485 (4.5%) TSA, respectively. One-fifth of this cohort (18.1%; 110/609) had unknown fellowship training: they either reported no fellowship (13.6%; 83/609) or did not specify the type of training (4.4%; 27/609). Shoulder and elbow fellowship-trained surgeons performed more TSA (median: 89.0 TSA per surgeon between 2012 and 2014) than surgeons without shoulder and elbow fellowship training (median: 67.0 TSA per surgeon; P < 0.001). More than one-third (37%) of shoulder and elbow fellowship-trained surgeons’ surgical case volume was comprised of TSA, with an additional 35% from non-arthroplasty shoulder procedures (Figure 2). In order for the current supply of shoulder and elbow fellowship-trained surgeons to meet the Medicare TSA demand, each fellowship graduate would have to perform 140.6 TSA in Medicare patients annually. Shoulder and elbow fellowship-trained surgeons were more likely to practice in referral regions with an increased Medicare population (P < .001), an increased number of surgeons performing TSA (P < .001), and a higher proportion of Medicaid-eligible patients (P = .01; Table 4). Shoulder and elbow fellowship-trained surgeons (18.7 years post-medical school graduation) were also earlier in their careers than other consistent TSA surgeons (23.1 years post-graduation; P < .001).

DISCUSSION

Utilization of TSA has continued to rise; however, access to this cost-effective procedure was recently demonstrated to be limited.¹¹ In a separate analysis, we established the continued rise in use of TSA in the Medicare population, coupled with an increase in the number of surgeons routinely performing TSA.² Multiple analyses have demonstrated the importance of high-volume surgeons and hospitals familiar with the intricacies of shoulder arthroplasty concepts in minimizing complications, improving the quality and decreasing the cost of TSA.^6,10,17 Specifically, Singh and colleagues18 demonstrated from a multi-center registry that surgeons and hospitals with greater shoulder arthroplasty volumes had decreased intra-operative blood loss, operative time, and hospital length of stay. As the demand for TSA, both anatomic and reverse, continues to rise, it is imperative that the healthcare delivery system is optimized to provide the best possible care. Before we can determine whether specialized training in shoulder arthroplasty influences surgical outcomes, characteristics and training of surgeons performing TSA should be described. 

The number of surgeons performing >10 TSA in the Medicare population rose significantly between 2012 and 2014 (29.3%). However, the number of TSAs per surgeon over this time period remained consistent (approximately 25 per surgeon). Furthermore, the increase in the number of surgeons performing a reportable volume of TSA by 2014 was from the addition of already active surgeons (ie, the growth in TSA was not from the addition of newly trained arthroplasty surgeons but originated from the existing orthopedic surgeon workforce). In a recently published analysis, Somerson and colleagues, ¹¹ using this same dataset, demonstrated persistent limitations in access to high-volume TSA surgeons. In a more recent analysis, we showed that while still lacking for some patients, access to a high-volume TSA surgeon has improved significantly over the past 3 years, with 96.9% of the United States population residing within 200 kilometers of a high-volume TSA surgeon (>20 Medicare cases).² This analysis validates those findings, with the caveat that the average annual volume per surgeon is not increasing. What remains unknown, due to limitations of this dataset, is how many surgeons are not identified because they are performing ≤10 TSA each year or are performing TSA in non-Medicare patients. 

With the specialization of healthcare delivery, specifically in orthopedics, it is imperative that mechanisms for providing specialty-focused care be established. However, the proportion of their practice that surgeons dedicate to TSA was unknown. This study demonstrates that this proportion is increasing. Including non-arthroplasty procedures, more than half (58%) of the procedures performed by this surgeon cohort were shoulder-specific. Furthermore, this analysis demonstrates that surgeons performing TSA have significant case diversity, including nearly half of the cohort performing TKA. Repeated evidence has demonstrated the effect of case volume on improved outcomes following orthopedic procedures.^8,19–21 The pre-existing location-based model for delivering orthopedic care supports case diversity; however, this model continues to be challenged with high-volume centers of excellence and patient travel.^22–24 Hip and knee arthroplasty experienced a similar surge in demand, with a subsequent shift in care to high-volume surgeons and centers.²⁵ Shoulder and elbow fellowship-trained surgeons would need to nearly quadruple their current Medicare TSA volume to meet the entire current demand for TSA in the Medicare population (and this does not account for TSA performed by very low-volume surgeons not included in this cohort). With increased utilization of TSA, policymakers and the orthopedic community must determine the structure of delivery (centers of excellence or medium-volume disseminated throughout the country) that is optimal. 

For those surgeons consistently performing TSA over the study period, fellowship training was diverse. While the current focus in orthopedics is on case volume, research in other specialties, namely general surgery, has provided repeated evidence that surgical specialization (more so than high case volume) provides improved outcomes.^26–29Furthermore, Leopold and colleagues³⁰ demonstrated an inverse relationship between competency in performing a procedure and confidence in one’s ability to do so. In their study, educational intervention provided improved competency in the procedure. Less than one-third (29.8%) of TSA in this cohort were performed by a shoulder and elbow fellowship-trained surgeon consistently performing this procedure. Approximately another quarter (26.2%) were performed by consistent TSA surgeons trained in sports surgery. Meanwhile, 34.6% of TSA in this study cohort were performed by a surgeon who did not consistently meet the minimum threshold in all study years (16,435 TSA; 22.8%) or by a surgeon performing TSA without fellowship training (8,489 TSA; 11.8%). There has been a trend toward orthopedic subspecialty training with an increased demand for fellowship-trained surgeons.³¹ Despite this and the complexities of TSA, many continue to be performed by surgeons with an inconsistent volume and those without arthroplasty-specific fellowship training. The available evidence supports a push toward the fellowship-trained, high-volume TSA surgeon in providing reproducible high-quality shoulder arthroplasty care. For now, that surgeon is more likely to be earlier in his/her career and reside in large, referral-based centers surrounded by other surgeons performing TSA.

These findings must be considered in the light of the study limitations. First, this is a large publicly available database. While this type of database provides a unique opportunity to assess the geographic distributions and characteristics of orthopedic surgeons, specifically those performing TSA, it completely prevents any assessment of the relationship between these findings and quality. As such, while the reader may generate hypotheses regarding the implications of our findings on the quality of TSA delivery, the true effects cannot be determined. In the same vein, for the purpose of privacy, surgeons performing ≤10 TSA were not included in this dataset. This limitation prevents the identification of low-volume TSA surgeons. Also, it is likely that the observed increase in surgeons over time is likely a reflection of small increases in volume for surgeons already performing TSA. Lastly, a web-based search was undertaken to identify surgeons’ self-reported fellowship training. The results of this web-based search could not be validated, and it is possible that fellowship training, or the lack thereof, was mischaracterized and simply not obtainable through a web-based search. Furthermore, it is not possible to fully assess the extent of high-quality TSA training in these various fellowships.

CONCLUSION

In just the past decade, the utilization of TSA in the Medicare population has increased significantly. However, this increase was not achieved by the addition of highly specialized, high-volume surgeons but by the addition of many surgeons performing lower numbers of TSA surgeries. Furthermore, for those performing this cost-effective procedure, TSA constitutes a relatively small proportion of the surgeries they perform. Shoulder and elbow fellowship-trained surgeons currently account for a low percentage of the overall number of surgeons performing TSA. The implications of these findings must be considered and investigated.

Total shoulder arthroplasty (TSA) has proved a cost-effective, reproducible procedure for multiple shoulder pathologies. As utilization of TSA continues to grow, it is important to investigate procedure diversity, training, and other characteristics of surgeons performing TSA. To identify surgeons performing TSA in the Medicare population, the Medicare Provider Utilization and Payment Databases from 2012 through 2014 were used. This dataset includes any provider who bills Medicare >10 times with a single billing code. A web-based search was performed for each physician performing >10 TSA in all years of the study to identify their surgical training characteristics. Between 2012 and 2014, 1374 surgeons (39 females [2.8%]) performed >10 TSA in Medicare patients in at least 1 year (71,973 TSA). Only 44.3% (609/1374) of surgeons met this threshold for all 3 years (55,538 TSA). Of these 609 surgeons, 191 (31.3%) were shoulder and elbow fellowship trained (21,444 TSA). Shoulder and elbow fellowship-trained surgeons were at earlier points in their careers and practiced in large referral-based centers with other surgeons performing TSA. In addition to TSA, surgeons performed other non-arthroplasty shoulder procedures (80.2% of surgeons), total knee arthroplasty (46.3%), repairs of traumatic injuries (29.8%), total hip arthroplasty (27.8%), non-arthroplasty knee surgeries (27.2%), elbow procedures (19.6%), and hand surgery (15.4%) during the study period. With less than one-third of TSA performed by shoulder and elbow fellowship-trained surgeons with consistent moderate-volume practices, the impact of consistent high-volume practices and targeted fellowship training on quality must be determined.

With the adoption of reverse shoulder arthroplasty, utilization of total shoulder arthroplasty (TSA) has increased substantially over the last decade.^1–3 Such increases are likely secondary to an aging population, increased comfort with the procedure, and the adoption of broadened indications for reverse shoulder arthroplasty, especially in the setting of proximal humerus fractures in the elderly.^4–7 Between 2012 and 2014 alone, the number of surgeons performing >10 TSA in Medicare patients annually increased by 28.6% (824 to 1060 surgeons) providing a 26.6% (20,824-26,365 procedures) increase in national volume in the Medicare population.2 With this boom in utilization, scrutiny of this now routine procedure and those performing it is necessary.

Prior reviews have demonstrated a strong link between surgeon and hospital TSA volume and outcomes of the procedure.^8–10 Somerson and colleagues¹¹ investigated fellowship training among surgeons performing TSA in 2012 and found that only 28% had completed a shoulder and elbow fellowship. In addition to prior analyses2, ¹², Somerson and colleagues confirmed a persistent geographic variation in utilization of TSA.¹¹ In conjunction with the evolution of shoulder arthroplasty, dedicated shoulder and elbow fellowship training has expanded. With a shift toward specialization in care, nearly 90% of orthopedic surgery residents plan to pursue shoulder and elbow fellowships, comprising 4.6% of (42/897) of available positions.¹³  

What remains unknown is the specialization of surgeons performing TSA, the regularity of their arthroplasty volume, and trends in TSA specialization over time. Therefore, this study aims to (a) identify surgeons performing shoulder arthroplasty and cohort changes over time, (b) determine the case profile of surgeons consistently performing shoulder arthroplasty, and (c) establish the characteristics of shoulder arthroplasty surgeons with a specific focus on fellowship training. 

METHODS

Prior to collecting surgeon-specific data, we identified surgeons performing TSA through the Centers for Medicare and Medicaid Services’ public release of “Medicare Provider Utilization and Payment Data: Physician and Other Supplier.”¹⁴ Datasets from 2012, 2013, and 2014 were used to identify all surgeons performing >10 TSAs (Current Procedural Terminology [CPT] Code 23472) during at least 1 of those years. This dataset provides the name, identification number, address, and all billing (by volume) for each unique CPT code submitted ≥10 times in a calendar year.

Once the cohort of surgeons had been generated, the number of surgeons consistently performing TSA year-over-year was determined. This allowed for an analysis of the consistency with which surgeons are performing moderate- to high-volume TSA. To form a case profile of surgeons performing TSA and observe how this shifted over time, a count and a description of each CPT code submitted by each surgeon was identified. To maintain patient privacy, only those claims made >10 times are reported for a provider (both physicians and physician-extenders are included in this dataset). First, all CPT codes were reviewed and tagged as surgical or non-surgical events. Then, every procedural CPT code identified was reviewed and categorized based upon anatomic location and procedure (eg, total knee arthroplasty [TKA]). It is important to note that all claims in this dataset are limited to those patients participating in Medicare’s fee-for-service program. 

Specialization was defined as the number of categorized procedures as a percentage of all procedures performed on Medicare patients. The trends for national, regional, and individual specialization of TSA, arthroplasty (major joint), and shoulder procedures were determined.

To investigate the characteristics of surgeons consistently performing TSA, all surgeons performing a minimum of 11 TSA in Medicare fee-for-service beneficiaries in all years between 2012 and 2014 were identified. Such surgeons were defined as consistent TSA surgeons. Investigation of this cohort included a web-based search of their self-reported post-graduate fellowship training and year of graduation from medical school. Using these data, the percentage of surgeons performing TSA who underwent formal shoulder and elbow training was determined. In addition, the impact of fellowship training on shoulder specialization and practice location was determined. Surgeons who had completed multiple fellowships were categorized under all of them. As such, there may be some duplication of surgeons in the comparisons. In addition, other potential characteristics of shoulder and elbow fellowship-trained surgeons were investigated: number of regional shoulder surgeons, urban area, total number of Medicare beneficiaries, average reimbursement for TSA, ethnicity of Medicare beneficiaries, and percentage of Medicare patients eligible for Medicaid. Geographic regions were defined by the Dartmouth Atlas and assigned by hospital referral region.¹⁵ These defined regions were used to assess the beneficiaries (number and characteristics) that individual surgeons were likely serving. The United States Census Bureau characterization of zip code-based regions as urban areas (population >50,000), urban clusters (2500 to 50,000), and rural region (<2500) was used to categorize practice location.¹⁶ 

Descriptive statistics were used initially to report these findings. To analyze predictors of utilization and specialization, comparative statistics were undertaken. For comparison of binomial variables between groups, a χ2analysis was utilized. For continuous variables, data normality was assessed. A skewness and kurtosis <2 and 12, respectively, was considered to represent parametric data. For parametric data, the mean was reported; conversely, the median is reported for non-parametric data. To assess continuous variables between groups, a t test or a Wilcoxon rank-sum test was used for parametric and non-parametric distributions, respectively. 

RESULTS

Between 2012 and 2014, 1374 surgeons (39 females [2.8%]) performed >10 TSA in Medicare patients in at least 1 year, for a combined total of 71,973 TSAs (Table 1). In 2012, only 834 surgeons (13 females [1.6%]) performed a minimum of 10 TSA in Medicare patients (21,137 arthroplasties; 25.3 per surgeon). This increased to 1078 surgeons (33 females [3.1%]; P = .04) performing 26,865 TSA (24.92 per surgeon) in 2014. Utilization of non-physician assistants in TSA also increased significantly over this period, with 307 assisting in 6885 TSAs (22.4 per provider) in 2012 and 465 assisting 10,433 TSA (22.4 per provider) in 2014. When all procedures were considered, including those performed at outpatient visits, 1319 physicians (95.9% of cohort) were active in 2012—providing either surgical procedures or outpatient consults to the Medicare population. Yet, only 63.2% performed >10 TSA in Medicare patients. The number of active surgeons performing TSA increased to 79.6% (1078/1353) in 2014 (P < .001).

In addition to TSA, this cohort of surgeons submitted 240 unique CPT codes with case volumes >10 annually over the 3-year study period. Of these, 80.2% (1102/1374) of surgeons performed non-arthroplasty shoulder procedures on Medicare patients, for a combined total of 202,335 procedures over the 3-year study period (Table 2). A significant proportion of these procedures were arthroscopic debridement (60,014 procedures performed by 908 surgeons) and arthroscopic rotator cuff repair (47,089 procedures performed by 809 surgeons). Just under half (49.1%; 674/1374) of surgeons performing TSA also performed TKA during this period (77,873 arthroplasties). Fewer surgeons (27.8%; 382/1374) performed total hip arthroplasty during this period (27,322 arthroplasties). Other procedure types that this group of surgeons routinely performed on Medicare patients were repairs of traumatic injuries (29.8%), non-arthroplasty knee surgeries (27.2%), elbow procedures (19.6%), and hand surgery (15.4%). By case load, non-arthroplasty shoulder procedures consisted of 43% of Medicare volume over the study period (Figure 1). Between 2012 and 2014, the average proportion of Medicare cases that were shoulder arthroplasties increased from 13.8% (21,137/152,862) to 16.7% (26,865/160,851; P = .001). Shoulder arthroplasty constituted 100% of the Medicare surgical case volume for 67 (4.9%; 67/1374) of the surgeons.

Only 44.3% (609/1374) of surgeons performed TSA in a minimum of 11 Medicare patients in all 3 years of the study period (consistent providers of TSA), providing a total of 55,538 TSA (77.2%; 55,538/71,973). When fellowship training was evaluated, 191 (31.4%; 191/609) of these surgeons were shoulder and elbow fellowship trained (21,444 TSA; 38.6%; Table 3). More than one-third (36.6%; 223/609) had completed a sports surgery fellowship (18,899 TSA; 34.0%). Surgeons trained in hand surgery (12.5%; 76/609) and adult reconstruction (5.3%; 32/610) also made contributions to meeting the TSA demand with 6971 (12.6%) and 2485 (4.5%) TSA, respectively. One-fifth of this cohort (18.1%; 110/609) had unknown fellowship training: they either reported no fellowship (13.6%; 83/609) or did not specify the type of training (4.4%; 27/609). Shoulder and elbow fellowship-trained surgeons performed more TSA (median: 89.0 TSA per surgeon between 2012 and 2014) than surgeons without shoulder and elbow fellowship training (median: 67.0 TSA per surgeon; P < 0.001). More than one-third (37%) of shoulder and elbow fellowship-trained surgeons’ surgical case volume was comprised of TSA, with an additional 35% from non-arthroplasty shoulder procedures (Figure 2). In order for the current supply of shoulder and elbow fellowship-trained surgeons to meet the Medicare TSA demand, each fellowship graduate would have to perform 140.6 TSA in Medicare patients annually. Shoulder and elbow fellowship-trained surgeons were more likely to practice in referral regions with an increased Medicare population (P < .001), an increased number of surgeons performing TSA (P < .001), and a higher proportion of Medicaid-eligible patients (P = .01; Table 4). Shoulder and elbow fellowship-trained surgeons (18.7 years post-medical school graduation) were also earlier in their careers than other consistent TSA surgeons (23.1 years post-graduation; P < .001).

DISCUSSION

Utilization of TSA has continued to rise; however, access to this cost-effective procedure was recently demonstrated to be limited.¹¹ In a separate analysis, we established the continued rise in use of TSA in the Medicare population, coupled with an increase in the number of surgeons routinely performing TSA.² Multiple analyses have demonstrated the importance of high-volume surgeons and hospitals familiar with the intricacies of shoulder arthroplasty concepts in minimizing complications, improving the quality and decreasing the cost of TSA.^6,10,17 Specifically, Singh and colleagues18 demonstrated from a multi-center registry that surgeons and hospitals with greater shoulder arthroplasty volumes had decreased intra-operative blood loss, operative time, and hospital length of stay. As the demand for TSA, both anatomic and reverse, continues to rise, it is imperative that the healthcare delivery system is optimized to provide the best possible care. Before we can determine whether specialized training in shoulder arthroplasty influences surgical outcomes, characteristics and training of surgeons performing TSA should be described. 

The number of surgeons performing >10 TSA in the Medicare population rose significantly between 2012 and 2014 (29.3%). However, the number of TSAs per surgeon over this time period remained consistent (approximately 25 per surgeon). Furthermore, the increase in the number of surgeons performing a reportable volume of TSA by 2014 was from the addition of already active surgeons (ie, the growth in TSA was not from the addition of newly trained arthroplasty surgeons but originated from the existing orthopedic surgeon workforce). In a recently published analysis, Somerson and colleagues, ¹¹ using this same dataset, demonstrated persistent limitations in access to high-volume TSA surgeons. In a more recent analysis, we showed that while still lacking for some patients, access to a high-volume TSA surgeon has improved significantly over the past 3 years, with 96.9% of the United States population residing within 200 kilometers of a high-volume TSA surgeon (>20 Medicare cases).² This analysis validates those findings, with the caveat that the average annual volume per surgeon is not increasing. What remains unknown, due to limitations of this dataset, is how many surgeons are not identified because they are performing ≤10 TSA each year or are performing TSA in non-Medicare patients. 

With the specialization of healthcare delivery, specifically in orthopedics, it is imperative that mechanisms for providing specialty-focused care be established. However, the proportion of their practice that surgeons dedicate to TSA was unknown. This study demonstrates that this proportion is increasing. Including non-arthroplasty procedures, more than half (58%) of the procedures performed by this surgeon cohort were shoulder-specific. Furthermore, this analysis demonstrates that surgeons performing TSA have significant case diversity, including nearly half of the cohort performing TKA. Repeated evidence has demonstrated the effect of case volume on improved outcomes following orthopedic procedures.^8,19–21 The pre-existing location-based model for delivering orthopedic care supports case diversity; however, this model continues to be challenged with high-volume centers of excellence and patient travel.^22–24 Hip and knee arthroplasty experienced a similar surge in demand, with a subsequent shift in care to high-volume surgeons and centers.²⁵ Shoulder and elbow fellowship-trained surgeons would need to nearly quadruple their current Medicare TSA volume to meet the entire current demand for TSA in the Medicare population (and this does not account for TSA performed by very low-volume surgeons not included in this cohort). With increased utilization of TSA, policymakers and the orthopedic community must determine the structure of delivery (centers of excellence or medium-volume disseminated throughout the country) that is optimal. 

For those surgeons consistently performing TSA over the study period, fellowship training was diverse. While the current focus in orthopedics is on case volume, research in other specialties, namely general surgery, has provided repeated evidence that surgical specialization (more so than high case volume) provides improved outcomes.^26–29Furthermore, Leopold and colleagues³⁰ demonstrated an inverse relationship between competency in performing a procedure and confidence in one’s ability to do so. In their study, educational intervention provided improved competency in the procedure. Less than one-third (29.8%) of TSA in this cohort were performed by a shoulder and elbow fellowship-trained surgeon consistently performing this procedure. Approximately another quarter (26.2%) were performed by consistent TSA surgeons trained in sports surgery. Meanwhile, 34.6% of TSA in this study cohort were performed by a surgeon who did not consistently meet the minimum threshold in all study years (16,435 TSA; 22.8%) or by a surgeon performing TSA without fellowship training (8,489 TSA; 11.8%). There has been a trend toward orthopedic subspecialty training with an increased demand for fellowship-trained surgeons.³¹ Despite this and the complexities of TSA, many continue to be performed by surgeons with an inconsistent volume and those without arthroplasty-specific fellowship training. The available evidence supports a push toward the fellowship-trained, high-volume TSA surgeon in providing reproducible high-quality shoulder arthroplasty care. For now, that surgeon is more likely to be earlier in his/her career and reside in large, referral-based centers surrounded by other surgeons performing TSA.

These findings must be considered in the light of the study limitations. First, this is a large publicly available database. While this type of database provides a unique opportunity to assess the geographic distributions and characteristics of orthopedic surgeons, specifically those performing TSA, it completely prevents any assessment of the relationship between these findings and quality. As such, while the reader may generate hypotheses regarding the implications of our findings on the quality of TSA delivery, the true effects cannot be determined. In the same vein, for the purpose of privacy, surgeons performing ≤10 TSA were not included in this dataset. This limitation prevents the identification of low-volume TSA surgeons. Also, it is likely that the observed increase in surgeons over time is likely a reflection of small increases in volume for surgeons already performing TSA. Lastly, a web-based search was undertaken to identify surgeons’ self-reported fellowship training. The results of this web-based search could not be validated, and it is possible that fellowship training, or the lack thereof, was mischaracterized and simply not obtainable through a web-based search. Furthermore, it is not possible to fully assess the extent of high-quality TSA training in these various fellowships.

CONCLUSION

In just the past decade, the utilization of TSA in the Medicare population has increased significantly. However, this increase was not achieved by the addition of highly specialized, high-volume surgeons but by the addition of many surgeons performing lower numbers of TSA surgeries. Furthermore, for those performing this cost-effective procedure, TSA constitutes a relatively small proportion of the surgeries they perform. Shoulder and elbow fellowship-trained surgeons currently account for a low percentage of the overall number of surgeons performing TSA. The implications of these findings must be considered and investigated.

ABSTRACT

Total shoulder arthroplasty (TSA) has proved a cost-effective, reproducible procedure for multiple shoulder pathologies. As utilization of TSA continues to grow, it is important to investigate procedure diversity, training, and other characteristics of surgeons performing TSA. To identify surgeons performing TSA in the Medicare population, the Medicare Provider Utilization and Payment Databases from 2012 through 2014 were used. This dataset includes any provider who bills Medicare >10 times with a single billing code. A web-based search was performed for each physician performing >10 TSA in all years of the study to identify their surgical training characteristics. Between 2012 and 2014, 1374 surgeons (39 females [2.8%]) performed >10 TSA in Medicare patients in at least 1 year (71,973 TSA). Only 44.3% (609/1374) of surgeons met this threshold for all 3 years (55,538 TSA). Of these 609 surgeons, 191 (31.3%) were shoulder and elbow fellowship trained (21,444 TSA). Shoulder and elbow fellowship-trained surgeons were at earlier points in their careers and practiced in large referral-based centers with other surgeons performing TSA. In addition to TSA, surgeons performed other non-arthroplasty shoulder procedures (80.2% of surgeons), total knee arthroplasty (46.3%), repairs of traumatic injuries (29.8%), total hip arthroplasty (27.8%), non-arthroplasty knee surgeries (27.2%), elbow procedures (19.6%), and hand surgery (15.4%) during the study period. With less than one-third of TSA performed by shoulder and elbow fellowship-trained surgeons with consistent moderate-volume practices, the impact of consistent high-volume practices and targeted fellowship training on quality must be determined.

With the adoption of reverse shoulder arthroplasty, utilization of total shoulder arthroplasty (TSA) has increased substantially over the last decade.^1–3 Such increases are likely secondary to an aging population, increased comfort with the procedure, and the adoption of broadened indications for reverse shoulder arthroplasty, especially in the setting of proximal humerus fractures in the elderly.^4–7 Between 2012 and 2014 alone, the number of surgeons performing >10 TSA in Medicare patients annually increased by 28.6% (824 to 1060 surgeons) providing a 26.6% (20,824-26,365 procedures) increase in national volume in the Medicare population.2 With this boom in utilization, scrutiny of this now routine procedure and those performing it is necessary.

Prior reviews have demonstrated a strong link between surgeon and hospital TSA volume and outcomes of the procedure.^8–10 Somerson and colleagues¹¹ investigated fellowship training among surgeons performing TSA in 2012 and found that only 28% had completed a shoulder and elbow fellowship. In addition to prior analyses2, ¹², Somerson and colleagues confirmed a persistent geographic variation in utilization of TSA.¹¹ In conjunction with the evolution of shoulder arthroplasty, dedicated shoulder and elbow fellowship training has expanded. With a shift toward specialization in care, nearly 90% of orthopedic surgery residents plan to pursue shoulder and elbow fellowships, comprising 4.6% of (42/897) of available positions.¹³  

What remains unknown is the specialization of surgeons performing TSA, the regularity of their arthroplasty volume, and trends in TSA specialization over time. Therefore, this study aims to (a) identify surgeons performing shoulder arthroplasty and cohort changes over time, (b) determine the case profile of surgeons consistently performing shoulder arthroplasty, and (c) establish the characteristics of shoulder arthroplasty surgeons with a specific focus on fellowship training. 

METHODS

Prior to collecting surgeon-specific data, we identified surgeons performing TSA through the Centers for Medicare and Medicaid Services’ public release of “Medicare Provider Utilization and Payment Data: Physician and Other Supplier.”¹⁴ Datasets from 2012, 2013, and 2014 were used to identify all surgeons performing >10 TSAs (Current Procedural Terminology [CPT] Code 23472) during at least 1 of those years. This dataset provides the name, identification number, address, and all billing (by volume) for each unique CPT code submitted ≥10 times in a calendar year.

Once the cohort of surgeons had been generated, the number of surgeons consistently performing TSA year-over-year was determined. This allowed for an analysis of the consistency with which surgeons are performing moderate- to high-volume TSA. To form a case profile of surgeons performing TSA and observe how this shifted over time, a count and a description of each CPT code submitted by each surgeon was identified. To maintain patient privacy, only those claims made >10 times are reported for a provider (both physicians and physician-extenders are included in this dataset). First, all CPT codes were reviewed and tagged as surgical or non-surgical events. Then, every procedural CPT code identified was reviewed and categorized based upon anatomic location and procedure (eg, total knee arthroplasty [TKA]). It is important to note that all claims in this dataset are limited to those patients participating in Medicare’s fee-for-service program. 

Specialization was defined as the number of categorized procedures as a percentage of all procedures performed on Medicare patients. The trends for national, regional, and individual specialization of TSA, arthroplasty (major joint), and shoulder procedures were determined.

To investigate the characteristics of surgeons consistently performing TSA, all surgeons performing a minimum of 11 TSA in Medicare fee-for-service beneficiaries in all years between 2012 and 2014 were identified. Such surgeons were defined as consistent TSA surgeons. Investigation of this cohort included a web-based search of their self-reported post-graduate fellowship training and year of graduation from medical school. Using these data, the percentage of surgeons performing TSA who underwent formal shoulder and elbow training was determined. In addition, the impact of fellowship training on shoulder specialization and practice location was determined. Surgeons who had completed multiple fellowships were categorized under all of them. As such, there may be some duplication of surgeons in the comparisons. In addition, other potential characteristics of shoulder and elbow fellowship-trained surgeons were investigated: number of regional shoulder surgeons, urban area, total number of Medicare beneficiaries, average reimbursement for TSA, ethnicity of Medicare beneficiaries, and percentage of Medicare patients eligible for Medicaid. Geographic regions were defined by the Dartmouth Atlas and assigned by hospital referral region.¹⁵ These defined regions were used to assess the beneficiaries (number and characteristics) that individual surgeons were likely serving. The United States Census Bureau characterization of zip code-based regions as urban areas (population >50,000), urban clusters (2500 to 50,000), and rural region (<2500) was used to categorize practice location.¹⁶ 

Descriptive statistics were used initially to report these findings. To analyze predictors of utilization and specialization, comparative statistics were undertaken. For comparison of binomial variables between groups, a χ2analysis was utilized. For continuous variables, data normality was assessed. A skewness and kurtosis <2 and 12, respectively, was considered to represent parametric data. For parametric data, the mean was reported; conversely, the median is reported for non-parametric data. To assess continuous variables between groups, a t test or a Wilcoxon rank-sum test was used for parametric and non-parametric distributions, respectively. 

RESULTS

Between 2012 and 2014, 1374 surgeons (39 females [2.8%]) performed >10 TSA in Medicare patients in at least 1 year, for a combined total of 71,973 TSAs (Table 1). In 2012, only 834 surgeons (13 females [1.6%]) performed a minimum of 10 TSA in Medicare patients (21,137 arthroplasties; 25.3 per surgeon). This increased to 1078 surgeons (33 females [3.1%]; P = .04) performing 26,865 TSA (24.92 per surgeon) in 2014. Utilization of non-physician assistants in TSA also increased significantly over this period, with 307 assisting in 6885 TSAs (22.4 per provider) in 2012 and 465 assisting 10,433 TSA (22.4 per provider) in 2014. When all procedures were considered, including those performed at outpatient visits, 1319 physicians (95.9% of cohort) were active in 2012—providing either surgical procedures or outpatient consults to the Medicare population. Yet, only 63.2% performed >10 TSA in Medicare patients. The number of active surgeons performing TSA increased to 79.6% (1078/1353) in 2014 (P < .001).

In addition to TSA, this cohort of surgeons submitted 240 unique CPT codes with case volumes >10 annually over the 3-year study period. Of these, 80.2% (1102/1374) of surgeons performed non-arthroplasty shoulder procedures on Medicare patients, for a combined total of 202,335 procedures over the 3-year study period (Table 2). A significant proportion of these procedures were arthroscopic debridement (60,014 procedures performed by 908 surgeons) and arthroscopic rotator cuff repair (47,089 procedures performed by 809 surgeons). Just under half (49.1%; 674/1374) of surgeons performing TSA also performed TKA during this period (77,873 arthroplasties). Fewer surgeons (27.8%; 382/1374) performed total hip arthroplasty during this period (27,322 arthroplasties). Other procedure types that this group of surgeons routinely performed on Medicare patients were repairs of traumatic injuries (29.8%), non-arthroplasty knee surgeries (27.2%), elbow procedures (19.6%), and hand surgery (15.4%). By case load, non-arthroplasty shoulder procedures consisted of 43% of Medicare volume over the study period (Figure 1). Between 2012 and 2014, the average proportion of Medicare cases that were shoulder arthroplasties increased from 13.8% (21,137/152,862) to 16.7% (26,865/160,851; P = .001). Shoulder arthroplasty constituted 100% of the Medicare surgical case volume for 67 (4.9%; 67/1374) of the surgeons.

Only 44.3% (609/1374) of surgeons performed TSA in a minimum of 11 Medicare patients in all 3 years of the study period (consistent providers of TSA), providing a total of 55,538 TSA (77.2%; 55,538/71,973). When fellowship training was evaluated, 191 (31.4%; 191/609) of these surgeons were shoulder and elbow fellowship trained (21,444 TSA; 38.6%; Table 3). More than one-third (36.6%; 223/609) had completed a sports surgery fellowship (18,899 TSA; 34.0%). Surgeons trained in hand surgery (12.5%; 76/609) and adult reconstruction (5.3%; 32/610) also made contributions to meeting the TSA demand with 6971 (12.6%) and 2485 (4.5%) TSA, respectively. One-fifth of this cohort (18.1%; 110/609) had unknown fellowship training: they either reported no fellowship (13.6%; 83/609) or did not specify the type of training (4.4%; 27/609). Shoulder and elbow fellowship-trained surgeons performed more TSA (median: 89.0 TSA per surgeon between 2012 and 2014) than surgeons without shoulder and elbow fellowship training (median: 67.0 TSA per surgeon; P < 0.001). More than one-third (37%) of shoulder and elbow fellowship-trained surgeons’ surgical case volume was comprised of TSA, with an additional 35% from non-arthroplasty shoulder procedures (Figure 2). In order for the current supply of shoulder and elbow fellowship-trained surgeons to meet the Medicare TSA demand, each fellowship graduate would have to perform 140.6 TSA in Medicare patients annually. Shoulder and elbow fellowship-trained surgeons were more likely to practice in referral regions with an increased Medicare population (P < .001), an increased number of surgeons performing TSA (P < .001), and a higher proportion of Medicaid-eligible patients (P = .01; Table 4). Shoulder and elbow fellowship-trained surgeons (18.7 years post-medical school graduation) were also earlier in their careers than other consistent TSA surgeons (23.1 years post-graduation; P < .001).

DISCUSSION

Utilization of TSA has continued to rise; however, access to this cost-effective procedure was recently demonstrated to be limited.¹¹ In a separate analysis, we established the continued rise in use of TSA in the Medicare population, coupled with an increase in the number of surgeons routinely performing TSA.² Multiple analyses have demonstrated the importance of high-volume surgeons and hospitals familiar with the intricacies of shoulder arthroplasty concepts in minimizing complications, improving the quality and decreasing the cost of TSA.^6,10,17 Specifically, Singh and colleagues18 demonstrated from a multi-center registry that surgeons and hospitals with greater shoulder arthroplasty volumes had decreased intra-operative blood loss, operative time, and hospital length of stay. As the demand for TSA, both anatomic and reverse, continues to rise, it is imperative that the healthcare delivery system is optimized to provide the best possible care. Before we can determine whether specialized training in shoulder arthroplasty influences surgical outcomes, characteristics and training of surgeons performing TSA should be described. 

The number of surgeons performing >10 TSA in the Medicare population rose significantly between 2012 and 2014 (29.3%). However, the number of TSAs per surgeon over this time period remained consistent (approximately 25 per surgeon). Furthermore, the increase in the number of surgeons performing a reportable volume of TSA by 2014 was from the addition of already active surgeons (ie, the growth in TSA was not from the addition of newly trained arthroplasty surgeons but originated from the existing orthopedic surgeon workforce). In a recently published analysis, Somerson and colleagues, ¹¹ using this same dataset, demonstrated persistent limitations in access to high-volume TSA surgeons. In a more recent analysis, we showed that while still lacking for some patients, access to a high-volume TSA surgeon has improved significantly over the past 3 years, with 96.9% of the United States population residing within 200 kilometers of a high-volume TSA surgeon (>20 Medicare cases).² This analysis validates those findings, with the caveat that the average annual volume per surgeon is not increasing. What remains unknown, due to limitations of this dataset, is how many surgeons are not identified because they are performing ≤10 TSA each year or are performing TSA in non-Medicare patients. 

With the specialization of healthcare delivery, specifically in orthopedics, it is imperative that mechanisms for providing specialty-focused care be established. However, the proportion of their practice that surgeons dedicate to TSA was unknown. This study demonstrates that this proportion is increasing. Including non-arthroplasty procedures, more than half (58%) of the procedures performed by this surgeon cohort were shoulder-specific. Furthermore, this analysis demonstrates that surgeons performing TSA have significant case diversity, including nearly half of the cohort performing TKA. Repeated evidence has demonstrated the effect of case volume on improved outcomes following orthopedic procedures.^8,19–21 The pre-existing location-based model for delivering orthopedic care supports case diversity; however, this model continues to be challenged with high-volume centers of excellence and patient travel.^22–24 Hip and knee arthroplasty experienced a similar surge in demand, with a subsequent shift in care to high-volume surgeons and centers.²⁵ Shoulder and elbow fellowship-trained surgeons would need to nearly quadruple their current Medicare TSA volume to meet the entire current demand for TSA in the Medicare population (and this does not account for TSA performed by very low-volume surgeons not included in this cohort). With increased utilization of TSA, policymakers and the orthopedic community must determine the structure of delivery (centers of excellence or medium-volume disseminated throughout the country) that is optimal. 

For those surgeons consistently performing TSA over the study period, fellowship training was diverse. While the current focus in orthopedics is on case volume, research in other specialties, namely general surgery, has provided repeated evidence that surgical specialization (more so than high case volume) provides improved outcomes.^26–29Furthermore, Leopold and colleagues³⁰ demonstrated an inverse relationship between competency in performing a procedure and confidence in one’s ability to do so. In their study, educational intervention provided improved competency in the procedure. Less than one-third (29.8%) of TSA in this cohort were performed by a shoulder and elbow fellowship-trained surgeon consistently performing this procedure. Approximately another quarter (26.2%) were performed by consistent TSA surgeons trained in sports surgery. Meanwhile, 34.6% of TSA in this study cohort were performed by a surgeon who did not consistently meet the minimum threshold in all study years (16,435 TSA; 22.8%) or by a surgeon performing TSA without fellowship training (8,489 TSA; 11.8%). There has been a trend toward orthopedic subspecialty training with an increased demand for fellowship-trained surgeons.³¹ Despite this and the complexities of TSA, many continue to be performed by surgeons with an inconsistent volume and those without arthroplasty-specific fellowship training. The available evidence supports a push toward the fellowship-trained, high-volume TSA surgeon in providing reproducible high-quality shoulder arthroplasty care. For now, that surgeon is more likely to be earlier in his/her career and reside in large, referral-based centers surrounded by other surgeons performing TSA.

These findings must be considered in the light of the study limitations. First, this is a large publicly available database. While this type of database provides a unique opportunity to assess the geographic distributions and characteristics of orthopedic surgeons, specifically those performing TSA, it completely prevents any assessment of the relationship between these findings and quality. As such, while the reader may generate hypotheses regarding the implications of our findings on the quality of TSA delivery, the true effects cannot be determined. In the same vein, for the purpose of privacy, surgeons performing ≤10 TSA were not included in this dataset. This limitation prevents the identification of low-volume TSA surgeons. Also, it is likely that the observed increase in surgeons over time is likely a reflection of small increases in volume for surgeons already performing TSA. Lastly, a web-based search was undertaken to identify surgeons’ self-reported fellowship training. The results of this web-based search could not be validated, and it is possible that fellowship training, or the lack thereof, was mischaracterized and simply not obtainable through a web-based search. Furthermore, it is not possible to fully assess the extent of high-quality TSA training in these various fellowships.

CONCLUSION

In just the past decade, the utilization of TSA in the Medicare population has increased significantly. However, this increase was not achieved by the addition of highly specialized, high-volume surgeons but by the addition of many surgeons performing lower numbers of TSA surgeries. Furthermore, for those performing this cost-effective procedure, TSA constitutes a relatively small proportion of the surgeries they perform. Shoulder and elbow fellowship-trained surgeons currently account for a low percentage of the overall number of surgeons performing TSA. The implications of these findings must be considered and investigated.

ABSTRACT

The decision to perform rotator cuff repair (RCR) versus reverse total shoulder arthroplasty (rTSA) for massive rotator cuff tear (MCT) without arthritis can be difficult. Our aim was to identify preoperative variables that are influential in a surgeon's decision to choose one of the two procedures and evaluate outcomes.

We retrospectively reviewed 181 patients older than 65 who underwent RCR or rTSA for MCT without arthritis. Clinical and radiographic data were collected and used to evaluate the preoperative variables in each of these two patient populations and assess outcomes.

Ninety-five shoulders underwent RCR and 92 underwent rTSA with an average followup of 44 and 47 months, respectively. Patients selected for RCR had greater preoperative flexion (113 vs 57), abduction (97 vs 53), and external rotation (42 vs 32), higher SST (3.1 vs 1.9) and ASES scores (43.8 vs 38.6), and were less likely to have had previous cuff surgery (6.3% vs 35.9%). Patients selected for rTSA had a smaller acromiohumeral interval (4.8 vs 8.7) and more superior subluxation (50.6% vs 14.1%). Similar preoperative characteristics included pain, comorbidities, and BMI. Patients were satisfied in both groups and had significant improvement in motion and function postoperatively.

Both RCR and rTSA can result in significant functional improvement and patient satisfaction in the setting of MCT without arthritis in patients older than 65. At our institution, patients who underwent rTSA had less pre-operative motion, lower function, more evidence of superior migration, and were more likely to have had previous rotator cuff surgery.

Continue to: The treatment of patients...

The treatment of patients with massive rotator cuff tears (MCTs) without osteoarthritis is challenging. This population is of considerable interest, as the prevalence of MCT has been reported to be as high as 40% of all rotator cuff tears.¹Options for surgical treatment in patients who have failed conservative management are numerous and include tendon debridement, partial or complete arthroscopic or open rotator cuff repair (RCR), tendon transfers, reverse total shoulder arthroplasty (rTSA), arthroscopic superior capsular reconstruction (ASCR), and other grafting procedures.² Arthroscopic superior capsular reconstruction shows promise as a novel technique, but it is not yet well studied. Other procedures such as tendon transfers fit into the treatment algorithm for only a small subset of patients. Open rotator cuff repair and rTSA are the 2 most commonly utilized procedures for MCT, and both have been shown to reliably achieve significant functional improvement and patient satisfaction.^3–6
