Retrospective multicentre study of 167 patients across 12 Austrian hospitals who underwent primary hemiarthroplasty for three- and four-part proximal humeral fractures and fracture-dislocations. The study asks which factors determine functional outcome, pain, and satisfaction after fracture arthroplasty. All patients had at least one year of clinical and radiological follow-up.
When you counsel a patient before fracture hemiarthroplasty, promise reliable pain relief but temper expectations on function. Fewer than half regain overhead elevation.
The mental model is simple: the prosthesis restores the articulation, but the rotator cuff drives motion, and the cuff only works if the tuberosities heal anatomically. This makes tuberosity reduction and fixation the technical crux of the entire operation.
A displaced tuberosity is almost as bad as a nonunion because it impinges mechanically. Use an image intensifier intraoperatively to confirm anatomical reduction.
Recognize the high-risk patient: advanced age and poor bone quality predict nonunion. The strong volume-outcome relationship (62% vs 31.8% nonunion) is a real argument for referring these technically demanding cases to experienced shoulder surgeons.
This paper is part of the evidence arc that shifted enthusiasm away from fracture hemiarthroplasty when reliable tuberosity healing cannot be achieved, foreshadowing the modern move toward reverse arthroplasty in the elderly.
