Total elbow arthroplasty is the current gold standard of treatment for unreconstructable distal humerus fractures; however, longevity implant remains a concern in younger, more active patients. Distal hemiarthroplasty offers an alternative and may allow durable results. The authors retrospectively evaluated short-term clinical outcomes 10 patients who underwent fractures. This review suggests that be effective certain Additional studies must conducted to further define role complex fractures humerus.

Avoiding delay in the surgical management of pectoralis major (PM) ruptures optimizes outcomes. However, this is not always possible, and when a tear becomes chronic or subacute has poor tissue quality, graft can facilitate reconstruction.The primary aim was to evaluate clinical outcomes PM reconstruction with dermal allograft augmentation for tears quality. A second determine patient factors affecting outcome.Case series; Level evidence, 4.Nineteen consecutive patients (19 ruptures) mean ±...
