Glenohumeral bone defects in the treatment of anterior shoulder instability.

There is a well-recognized association between osseous defects of the glenoid or humerus and shoulder dislocation, which often leads to recurrent instability. A variety of strategies have been used to treat bone loss, and procedures have become more refined as the goals of surgery have evolved. Achieving optimal motion and function and minimizing the risk of osteoarthritis have become almost as important as stabilizing the joint.
