The decision process regarding the surgical technique is challenging because of the variety of treatment options1,2. Although locked plate fixation has become a popular surgical technique for many proximal humeral fractures, other techniques such as pinning, wiring, and intramedullary nailing are useful in certain situations. Less invasive techniques provide the advantage of incorporating the rotator cuff insertion to increase fixation in patients with poor bone quality, as well as preserving the soft-tissue envelope and vascularity to the humeral head. Closed or open-pin fixation techniques for proximal humeral fractures have potential pitfalls such as malunion, nonunion, loss of fixation, pin-track infection, and pin migration3.
