Open shoulder stabilization procedure using bone block technique for treatment of chronic glenohumeral instability associated with bony glenoid deficiency.

We examined the early results of using an open bone block technique to stabilize the glenohumeral joint with chronic instability related to bony deficiency of the glenoid. Fifteen patients with anteroinferior glenoid bone loss on preoperative computed tomography underwent diagnostic shoulder arthroscopy (for evaluation of glenoid bony deficiency) and then open bone block augmentation of the anteroinferior glenoid rim. Clinical follow-up of 10 patients at a mean of 25 months showed a mean postoperative Constant score of 94 (range, 32-100), a mean University of California Los Angeles score of 32 (range, 9-35), and a mean American Shoulder and Elbow Surgeons score of 83 (range, 47-100).
