چکیده

Treatment of comminuted distal humeral fractures remains challenging. Open reduction-internal fixation remains the preferred treatment, but is not always feasible. In selected cases with non-reconstructable or highly comminuted fractures, total elbow arthroplasty has been used, however, also with relatively high complication and failure rates. Distal humerus prosthetic hemiarthroplasty (DHA) may be an alternative in these cases. The purpose of this study was to report the midterm results of six patients that were treated by DHA for acute and salvage treatment of non-reconstructable fractures of the distal humerus. All six patients were treated by DHA for acute and salvage treatment of non-reconstructable fractures of the distal humerus. Medical records were reviewed, and each patient was seen in the office. Mean follow-up was 54 months (range 21-76 months). Implant survival was 100 %. Three were pain free and three had mild or moderate residual pain. Average flexion-extension arc was 95.8° (range 70°-115°) and average pronation-supination arc was 165° (range 150°-180°). In three, there was some degree of instability, which was symptomatic in one. One had motoric and sensory sequelae of a partially recovered traumatic ulnar nerve lesion. According to the Mayo Elbow Performance Score, there were three excellent, one good and two poor results. Four were satisfied with the final result, and two were not. In this case series of six patients with DHA for non-reconstructable distal humerus fractures, favorable midterm follow-up results were seen; however, complications were also observed.

Hemiarthroplasty for the treatment of distal humerus fractures: short-term clinical results.

Total elbow arthroplasty is the current gold standard of treatment for unreconstructable distal humerus fractures; however, longevity of the implant remains a concern in younger, more active patients. Distal humerus hemiarthroplasty offers an alternative and may allow for more durable results. The authors retrospectively evaluated the short-term clinical outcomes of 10 patients who underwent el...

What is the Optimal Reconstruction Option after the Resection of Proximal Humeral Tumors? A Systematic Review

PURPOSE The proximal humerus is a common location for both primary and metastatic bone tumors. There are numerous reconstruction options after surgical resection. There is no consensus on the ideal method of reconstruction. METHODS A systematic review was performed with a focus on the surgical reconstructive options for lesions involving the proximal humerus. RESULTS A total of 50 articles ...

Outcome of shoulder hemiarthroplasty in acute proximal humeral fractures: a frustrating meta-analysis experience.

Limited evidence is available on the optimal treatment of complex fractures of the proximal humerus. No randomized prospective studies have compared hemiarthroplasty, open reduction internal fixation and/or conservative treatment. Two systematic reviews are available but they do not include angle-stable plate osteosynthesis or third-generation prosthetic designs. We conducted a systematic revie...

Complex Fracture Of The Proximal Humerus Treated With Shoulder Prosthesis

Fractures of the upper end of the humerus that interrupt the blood supply to the humeral head may justify a prosthetic replacement. A rigorous analysis of the patient's condition and the type of fracture is a prerequisite before rejecting an indication of orthopedic treatment or fixation. The result of a hemiarthroplasty is mainly conditioned by compliance with technical rules whose purpose is ...

Functional outcomes of reverse shoulder arthroplasty compared with hemiarthroplasty for acute proximal humeral fractures.

BACKGROUND Complex acute proximal humeral fractures may require prosthetic replacement of the proximal humerus. Reverse shoulder arthroplasty (RSA) has been suggested as an alternative to hemiarthroplasty in the management of such fractures. This study compared the functional outcomes of RSA with hemiarthroplasty in patients with acute proximal humeral fractures. MATERIALS AND METHODS All pat...
