Reverse Shoulder Arthroplasty for the Treatment of Proximal Humerus Fractures

Abstract

Proximal humerus fractures (PHFs) are relatively common fractures that are especially prevalent amongst the geriatric population. Various fracture patterns exist, ranging from minimally displaced fractures to fracture dislocations with multiple fragments. Traditionally, treatment strategies have included nonoperative management with a sling and gradual return to range of motion, as well as both open reduction internal fixation and hemiarthroplasty. Recently, there has been an increase in the frequency of utilization of reverse shoulder arthroplasty (RSA) as a treatment option for PHFs, to maximize mobility and function. The purpose of this article is to review current concepts for the treatment of PHFs, with a special focus on indications, technical pearls, clinical/functional outcomes, and complications for RSA as a definitive management strategy.
