Synovial chondromatosis: Report of a rare surgical problem of the temporomandibular joint.
Synovial chondromatosis of the joint is a rare benign condition characterized by the formation of metaplastic cartilage in the synovium of the joint resulting in numerous attached and unattached osteocartilagenous bodies. It may recur after surgical intervention. For this reason removal of the synovium and the bodies is advocated. This is a report of a case which occurred in the temporomandibular joint which had numerous loose bodies and exhibited features of degenerative joint disease as well. The loose bodies were removed, a high condylar shave performed and the synovium left intact. The patient is still free from joint problems five years later.
