Acromion and Scapular Spine Fractures Following Reverse Total Shoulder Arthroplasty

Reverse total shoulder arthroplasty (RSA) continues to see tremendous growth as the indications have expanded. A variety of complications have been described, including fractures of the acromion or scapular spine. These fractures are painful and can compromise shoulder stability and functional outcomes following RSA. Multiple studies have recently investigated the incidence, risk factors, and treatment strategies for these injuries. In this article, the authors review current literature and discuss the incidence, cause, associated risk factors, treatment options, and outcomes following fractures of the acromion or scapular spine after RSA.
