Though recurrent subluxation of the shoulder is not so rare, its pathology is seldom recognized. We operated on 40 cases of it and found that “Bankart lesion” was the most common pathological area. An injured labrum and capsule were relatively frequent in the middle or superior portions of the glenoid. The results after operation by the Bankart procedure in 36 cases and the Oudard-Iwahara procedure in 4 cases were all exellent or good with one exception. That patient complained of pain when he tried to move his shoulder in flexion or abduction. 69% of the our cases returned to doing the sports which they had done before the operation.
