Abstract

Subscapularis tears are becoming increasingly recognized as a cause of shoulder pain and disability. However, identifying the subscapularis tendon stump is often difficult during repair of chronic, retracted subscapularis tears that are scarred to the deltoid fascia. The authors have found the "comma sign," an arc formed by a portion of the superior glenohumeral ligament/coracohumeral ligament complex, to be a useful marker of the superolateral corner of the torn subscapularis tendon.
