With the advent of reverse shoulder arthroplasty, indications for hemiarthroplasty are changing and may best fit younger patients with comminuted fractures of the proximal humerus not amenable to open reduction and internal fixation. Hemiarthroplasty is the preferred option in three- and four-part fractures, which have a higher likelihood of osteonecrosis, malunion, and nonunion. In evaluating patients for hemiarthroplasty, the greater tuberosity should represent a large fragment with minimal comminution. In those cases where the greater tuberosity cannot be reconstructed, reverse total shoulder arthroplasty is the better option. |
