Selective capsular shift technique for anterior and anterior-inferior glenohumeral instability.

Anterior and anterior-inferior glenohumeral instability is often successfully treated with nonoperative measures, especially in atraumatic instability. In the case of traumatic instability, especially when the labrum is detached from the anteroinferior glenoid rim, surgery is often necessary to stabilize the shoulder and restore function. An anatomic repair that addresses any capsular or labral defect is essential for a successful outcome, and the selective capsular shift technique offers the flexibility necessary to correct these deformities. Several equally important steps must be followed when treating anterior and anterior-inferior glenohumeral instability. These include the correct diagnosis and indications for surgery; a technically successful surgical procedure; and diligent, physician-directed, closely monitored rehabilitation.
