Abstract
1. The operative findings in seventeen cases of recurrent dislocation of the shoulder are presented and discussed. Detachment of the glenoid labrum (thirteen cases) and the formation of a posterior humeral groove (eleven cases) were the most consistent findings.
2. In one case recurrent dislocation of the shoulder was due to avulsion of the subscapularis muscle.
3. The surgical treatment of these cases is described, usually consisting of a modification of Bankart's operation.
4. The results of follow-up are given as an intermediate report. No post-operative dislocation has so far been reported.
