F. Perry Wilson, MD, MSCE: I am joined today by Dr. Ohad Einav. He’s a staff surgeon in orthopedics at Hadassah Medical Center in Jerusalem. He’s with me to talk about an absolutely incredible surgical case, something that is terrifying to most non–orthopedic surgeons and I imagine is fairly scary for spine surgeons like him as well. But what we don’t have is information about how this works from a medical perspective. So, first of all, Dr. Einav, thank you for taking time to speak with me today.
Ohad Einav, MD: Thank you for having me.
Dr. Wilson: Can you tell us about Suleiman Hassan and what happened to him before he came into your care?
Dr. Einav: Hassan is a 12-year-old child who was riding his bicycle on the West Bank, about 40 minutes from here. Unfortunately, he was involved in a motor vehicle accident and he suffered injuries to his abdomen and cervical spine. He was transported to our service by helicopter from the scene of the accident.
Hadassah Medical Center
Dr. Wilson: “Injury to the cervical spine” might be something of an understatement. He had what’s called atlanto-occipital dislocation, colloquially often referred to as internal decapitation. Can you tell us what that means? It sounds terrifying.
Dr. Einav: It’s an injury to the ligaments between the occiput and the upper cervical spine, with or without bony fracture. The atlanto-occipital joint is formed by the superior articular facet of the atlas and the occipital condyle, stabilized by an articular capsule between the head and neck, and is supported by various ligaments around it that stabilize the joint and allow joint movements, including flexion, extension, and some rotation in the lower levels.
Dr. Wilson: This joint has several degrees of freedom, which means it needs a lot of support. With this type of injury, where essentially you have severing of the ligaments, is it usually survivable? How dangerous is this?
Dr. Einav: The mortality rate is 50%-60%, depending on the primary impact, the injury, transportation later on, and then the surgery and surgical management.
Dr. Wilson: Tell us a bit about this patient’s status when he came to your medical center. I assume he was in bad shape.
Dr. Einav: Hassan arrived at our medical center with a Glasgow Coma Scale score of 15. He was fully conscious. He was hemodynamically stable except for a bad laceration on his abdomen. He had a Philadelphia collar around his neck. He was transported by chopper because the paramedics suspected that he had a cervical spine injury and decided to bring him to a Level 1 trauma center.
He was monitored and we treated him according to the ATLS [advanced trauma life support] protocol. He didn’t have any gross sensory deficits, but he was a little confused about the whole situation and the accident. Therefore, we could do a general examination but we couldn’t rely on that regarding any sensory deficit that he may or may not have. We decided as a team that it would be better to slow down and control the situation. We decided not to operate on him immediately. We basically stabilized him and made sure that he didn’t have any traumatic internal organ damage. Later on we took him to the OR and performed surgery.
Dr. Wilson: It’s amazing that he had intact motor function, considering the extent of his injury. The spinal cord was spared somewhat during the injury. There must have been a moment when you realized that this kid, who was conscious and could move all four extremities, had a very severe neck injury. Was that due to a CT scan or physical exam? And what was your feeling when you saw that he had atlanto-occipital dislocation?
Dr. Einav: As a surgeon, you have a gut feeling in regard to the general examination of the patient. But I never rely on gut feelings. On the CT, I understood exactly what he had, what we needed to do, and the time frame.
Dr. Wilson: You’ve done these types of surgeries before, right? Obviously, no one has done a lot of them because this isn’t very common. But you knew what to do. Did you have a plan? Where does your experience come into play in a situation like this?
Dr. Einav: I graduated from the spine program of Toronto University, where I did a fellowship in trauma of the spine and complex spine surgery. I had very good teachers, and during my fellowship I treated a few cases in older patients that were similar but not the same. Therefore, I knew exactly what needed to be done.
Dr. Wilson: For those of us who aren’t surgeons, take us into the OR with you. This is obviously an incredibly delicate procedure. You are high up in the spinal cord at the base of the brain. The slightest mistake could have devastating consequences. What are the key elements of this procedure? What can go wrong here? What is the number-one thing you have to look out for when you’re trying to fix an internal decapitation?
Dr. Einav: The key element in surgeries of the cervical spine – trauma and complex spine surgery – is planning. I never go to the OR without knowing what I’m going to do. I have a few plans – plan A, plan B, plan C – in case something fails. So, I definitely know what the next step will be. I always think about the surgery a few hours before, if I have time to prepare.
The second thing that is very important is teamwork. The team needs to be coordinated. Everybody needs to know what their job is. With these types of injuries, it’s not the time for rookies. If you are new, please stand back and let the more experienced people do that job. I’m talking about surgeons, nurses, anesthesiologists – everyone.
Another important thing in planning is choosing the right hardware. For example, in this case we had a problem because most of the hardware is designed for adults, and we had to improvise because there isn’t a lot of hardware on the market for the pediatric population. The adult plates and screws are too big, so we had to improvise.
Dr. Wilson: Tell us more about that. How do you improvise spinal hardware for a 12-year-old?
