Management of Glenoid Bone Deficiency During Shoulder Replacement

Recent studies have shown that resurfacing the glenoid during shoulder replacement provides predictable pain relief and functional improvement for patients with degenerative arthritis. Therefore, the current trend is to replace the glenoid whenever the patient has adequate soft tissue support and glenoid bone stock. For patients who are believed to have a deficient glenoid, various approaches have been developed, and, in fact, the approach chosen depends largely on surgeon preference and experience. This article will review glenoid replacement and the surgical indications and different techniques that have developed for dealing with glenoid deficiency.
