Arthroscopic treatment for synovial chondromatosis of the shoulder.

Synovial chondromatosis of the shoulder is a rare condition. The following is a description of such a case with the presenting symptoms, radiographic features, intraoperative findings, and the arthroscopic technique for treatment of this disease. Loose bodies were found in the long head of the biceps tendon sheath, the subscapularis recess, and throughout the glenohumeral joint, causing erosive damage. We feel that arthroscopy allows for better visualization of the entire glenohumeral joint, including the long head of the biceps tendon sheath and the subscapularis recess, and for ease of loose body removal. Additional advantages of arthroscopy include decreased postoperative pain, early active range of motion, shorter course of rehabilitation, and earlier functional return.
