Hemiarthroplasty for the treatment of proximal humerus fractures

Abstract

Over the past decade, the indications for treating proximal humerus fractures with hemiarthroplasty have become more narrowed. Locking plates, reverse shoulder arthroplasty, and a better understanding of osteonecrosis have created a limited need for this procedure. Fractures which cannot be adequately reduced or in which adequate fixation cannot be achieved are candidates for joint replacement. Precise technique is required to produce good functional results. In inexperienced hand, outcomes are very inconsistent. This chapter reviews a method to achieve reliable results.
