Abstract
Failure to address glenoid deficiency/osteochondral defects can lead to persistent shoulder instability despite a surgical stabilization procedure. In patients with significant glenoid bone loss, osteoarticular allograft transplantation has the potential benefit of restoring normal glenohumeral anatomy. It may also reduce the risk of recurrent instability and permit near-normal postoperative range of motion while avoiding the complications of nonanatomic reconstruction techniques. Numerous open methods of anatomic glenoid reconstruction have been described, including the use of iliac crest autograft, distal tibia allograft, and glenoid allograft. Our purpose is to review the literature regarding the surgical treatment of glenoid bone deficiency. We also describe a novel technique of arthroscopic anteroinferior glenoid reconstruction using glenoid osteochondral allograft without subscapularis takedown. The potential risks and benefits of our technique are also discussed.
