Synovial Chondromatosis of the Elbow Causing a Mechanical Block to Range of Motion: A Case Report and Review of the Literature

We report a unique case of elbow synovial chondromatosis with sudden onset of severe loss of elbow extension and flexion range of motion caused by mechanical block from deposition of chondral fragments in the olecranon and coronoid fossae, respectively. We performed successful arthroscopic surgical treatment of synovial chondromatosis of the elbow. Arthroscopy examination revealed an acutely evolving synovial chondromatosis. Three-year follow-up indicated that arthroscopic removal of loose bodies and partial synovectomy can yield lasting improvement in motion without disease recurrence.
