Recurrent Shoulder Dislocations Secondary to Coracoid Process Fracture: A Case Report

Abstract

Coracoid process fracture is easily missed in recurrent anterior shoulder dislocation. We report one such case in a 48-year-old man. Radiology revealed the Bankart lesion and the Hill-Sachs lesion only; the coracoid process fracture was discovered intra-operatively. The anatomy of the shoulder was restored by fixing the fragment to its scapular remnant with a 4-mm cannulated cancellous screw. The tip and the proximal fragment were reamed before inserting the screw. This fragment was routed with attached short head of biceps and coracobrachialis through the lower one third of the subscapularis, before homing it and fixing it to the proximal coracoid fragment. This extra-articular repair resulted in less stiffness than any intra-articular procedure. At the 2-year follow-up, the patient had had no further shoulder dislocation.
