Arthroscopic treatment of synovial osteochondromatosis of the elbow. Case report and literature review


Synovial osteochondromatosis is a benign proliferative disorder with metaplasia of the synovial membrane that affects the fibroblasts of the synovial joints, tendons and bursae. In literature, there are few descriptions of synovial osteochondromatosis of the elbow. The objective of this article was to report a case of synovial osteochondromatosis of the elbow in a patient aged 32, basketball athlete, in which surgical treatment was chosen because of the pain and functional limitation and stage of disease with multiple loose bodies. Patient 32, male, presented with pain and limitation of motion of the elbow. The range of passive motion was 100° of flexion and 30° extension. The range of active motion was 40–90°. Magnetic resonance observed many loose bodies mainly in the posterior compartment in the olecranon fossa plus some chondral lesions in the capitellum. The arthroscopic treatment was chosen with two anteriors portals (medial and lateral) and two posterior portals (standard posterior and posterolateral) for easing loose bodies and osteoplasty of the olecranon fossa. The visual analog scale pain was 9–3 and its arc of active motion was 110° to −20° of flexion and extension. On a scale of performance from Mayo Clinic patients was 65 points preoperatively to 90 postoperatively with 9 months follow-up and the patient was satisfied with the treatment outcome. Arthroscopic treatment of synovial osteochondromatosis of the elbow is an effective and safe therapeutic management with low morbidity and early return to activities.
