We wished to report on the results of our modification of Bristow procedure. In our modification the coracoid process was transferred on the anteroinferior glenoid rim to extend the glenoid. 203 joints, which were followed-up for over five years after surgery, were investigated. 44 cases were female patients and 159 were male. Their mean age at the surgery was 25.3 years old. The mean follow-up period was 7 years and 10 months. Recurrence of dislocation was not recognized. The mean external rotation with arm at side after surgery was 45.6 degrees. The mean JSS shoulder instability score was 55.8 before surgery and 93.4 after surgery. Screw breakage occurred in 4 cases. Slight deformity of the humeral head was recognized in 4 cases. The sports return was as follows: full return: 63(36.4)%, level down: 23.9(36.4)%, changed sports: 8.7(13.6)%, stopped playing: 4.4(13.6)%(in cases which affected the dominant hand in overhead sports). No recurrence, easy procedure, wide application, and minimal complication were the most important results of the surgery for recurrent dislocation. In our modification of Bristow procedure, we can get a wide view of the gleno-humeral joint and we could transfer the coracoid process to the best position of the glenoid with the best direction. The operation could be finished within 45 minutes. Full return to the overhead sports was only 36.4% in cases affecting the dominant hand. It is the limit of this procedure. No recurrence was recognized and the results of our method were satisfactory.
