Double-Sling Augmentation for Anterior Shoulder Dislocation

Abstract

Anterior capsule ligament deficiency occurs in complicated anterior shoulder dislocation and poses a challenge to surgeons because of the irreparability of the capsule labrum structure or the nonoptimal healing potential after repair. Single-sling augmentation with either conjoined tendon or the long head of the biceps brachii has been reported to enhance the anterior stability of the shoulder. However, single-sling augmentation may still not be enough in cases of complicated anterior shoulder dislocation. Thus we introduce a double-sling anterior shoulder augmentation technique in which both the conjoined tendon and the long head of the biceps brachii are transferred to the anterior inferior side of the glenoid. Our clinical experience indicates that this procedure is effective to address complicated anterior shoulder dislocation. We believe that the introduction of this technique will provide a special choice in the treatment of anterior shoulder dislocation.
