Open reduction internal fixation of proximal humerus fractures is often accomplished with proximal humerus locking plates. While these plates have a good track record, they can become symptomatic and require removal once the fracture has healed. Open hardware removal is associated with a number of additional risks to the patient, including infection, scarring, nerve damage, and blood loss. In addition, the recovery time after open hardware removal may be prolonged, thereby predisposing the patient to postoperative stiffness. The purpose of this article is to describe a technique for removing proximal humerus locking plates arthroscopically. Although technically demanding, the benefits of this technique include smaller incisions, quicker recovery time, decreased risk of infection, and reduced blood loss. Arthroscopy also provides the surgeon with the ability to address concomitant intra-articular pathology at the time of surgery. Additionally, we use a bone-void filler to reduce the risk of fracture through stress caused by previous screw holes.
