Abstract

Comminuted proximal humeral fractures with displaced three- or four-part fragments, fracture-dislocations, and humeral head-splitting fractures are very difficult to treat. In older patients, hemiarthroplasty or reverse shoulder arthroplasty is often the indicated treatment. Arthroplasty in this patient cohort is a very technique-dependent procedure, and relies on preserving deltoid function, proper component placement and fixation, and tuberosity fixation. Although pain relief is predictable, it is often difficult to achieve functional improvement. Results depend on the patient's age, timing of the surgery, tuberosity healing, and adequate rehabilitation.
