Four-Layer Structural Reconstruction for Recurrent Anterior Shoulder Dislocation

Recurrent anterior shoulder dislocation is always combined with glenoid and capsule-labrum deficiency. To address all these deficiency in a single operation, we developed a 4-layer structural reconstruction technique at the anterior side of the shoulder, which includes capsule-labrum repair, glenoid bone grafting, and transfer of the long head of the biceps brachii (LHB). This procedure is indicated in patients who need both sling and bone fragment augmentation. The critical steps of this technique are LHB transfer and 2-layer glenoid bone grafting. We believe that this technique will enhance the field of anterior shoulder reconstruction for complicated anterior shoulder dislocation.
