A review of shoulder replacement surgery.

Shoulder replacement surgery is employed in the treatment of severe shoulder arthritis and following some proximal humeral fractures. Three different replacements are available: hemiarthroplasty (HAS), total shoulder replacement (TSR) and reverse shoulder replacement (RSR). HAS and TSR are indicated in patients with intact rotator cuffs and RSR for cuff deficient older patients. Outcomes are favourable, with the majority of patients having improvements in shoulder pain and function.
