Background: Repair of the anterior labrum (Bankart lesion) with tightening of the ligaments (capsulorrhaphy) is the recommended treatment for recurrent anterior glenohumeral dislocations. Current evidence suggests that arthroscopic anterior stabilization methods yield similar failure rates for resubluxation and redislocation when compared to open...

Normal shoulder function is dependent on a reciprocating relationship between glenohumeral mobility and stability. A large humeral head articulating with a small glenoid socket permits a wide range of motion at the glenohumeral joint, but compromises the stability of the joint. Glenohumeral stability is imparted by both static and dynamic structure...
