Arthroscopy of the shoulder joint--a cadaver and clinical study. Part 2: Clinical study.

Shoulder arthroscopy was carried out 56 times on 50 patients. Different types of arthroscopes were employed. Anterior and posterior approaches were used. Diagnoses were 21 cases of glenohumeral instability including 17 of recurrent anterior dislocation and subluxation; 2 of voluntary anterior subluxation and 2 of habitual posterior dislocation, 13 of rotator cuff tear, 6 of chronic subacromial bursitis, 2 of fracture-dislocation, 2 of frozen shoulder, 2 of baseball shoulder, one of rheumatoid arthritis, and 3 miscellaneous. The arthroscopic findings in the instability group and rotator cuff tear group were verified. Bankart lesion and Hill-Sachs lesion were identified arthroscopically. The indications for shoulder arthroscopy are outlined. There was no significant morbidity with this procedure.
