The radiograph demonstrates a humeral hemiarthroplasty. Malunion of the greater tuberosity is a known complication of this procedure, and the most likely cause for loss of shoulder elevation. Frankle et al in 2004 reported a 25% rate of greater tuberosity malunion. They discuss surgical techniques to improve fixation of the tuberosities following hemiarthroplasty for proximal humerus fractures. Frankle et al in 2002 evaluated 5 different techniques to reattach the tuberosities following shoulder hemiarthroplasty in human cadavers. Findings suggested that a circumferential medial cerclage should be placed around the tuberosities to enhance the stability of the tuberosity repair. Bosch et al reviewed 39 consecutive 3 or 4 part proximal humerus fractures that were treated with either primary hemiarthroplasty or secondary hemiarthroplasty following a primary ORIF. Patients who underwent primary hemiarthroplasty reported better clinical outcomes. The authors concluded that elderly patients with 3 or 4 part humerus fractures are best treated with early arthroplasty.
