Proximal humerus fractures.
Proximal humeral fractures are extremely common injuries, and are one of the true osteoporotic fractures. Most fractures can be effectively treated nonoperatively, as the rich vascularity and broad cancellous surfaces impart a high propensity for healing. Additionally, many fracture patterns result in adequate bone contact and minimal displacement with acceptable alignment. Open reduction and internal fixation of displaced fractures can improve outcomes, depending on the pre-injury functional status of the patient. If operative treatment is selected, unique treatment challenges must be overcome, including obtaining and maintaining reduction of small bone fragments with strong muscle forces, often in osteoporotic bone. Many options are feasible, including plates, nails, sutures, and other novel devices. Locking plates are the most common device used, but technical detail is critical to minimize the risk of implant failure, loss of reduction, and reoperation.
