ABSTRACT

Synovial chondromatosis is metaplasia of the synovial membrane of unknown origin and is a rare benign condition predominantly affecting the knee. We report in our work the clinical case of a patient who presents with late stage shoulder involvement with intermittent sensations of instability, blockage and creaking at shoulder mobilization. The diagnosis was made by simple x-ray demonstrating the presence of multiple clusters of calcified osteochondromas without osteoarthritis radiologic signs. He underwent extraction of foreign bodies through deltopectoral approach given the large number of osteochondromas and their multiple and diffuse locations associated with maneuvers of shoulder mobilization in circumduction and direct digital pressures, but without any synovectomy because of the late evolution stage of the ostechondromatosis in wich the synovial is quiescent. The first complication is the recurrence. it was not the case of our patient wich had good clinical and radiological outcomes. The ostechondromatosis should be treated as soon as possible before eventuel developpement of osteoarthritis.
