Emerging concepts in upper extremity trauma: humeral shaft fractures

Fractures of the humeral shaft are common in low-energy and high-energy trauma, and optimal clinical management remains controversial. Nonsurgical management has been supported as the preferred treatment based on high union rates and minimal functional deficit due to a rich vascular supply from overlying muscle and the wide motion available at the glenohumeral joint. Recent studies of nonoperative management have challenged surgeons' understanding of these fractures and the perception of favorable outcomes. Current considerations support expanded operative indications with traditional open-plate fixation and with the use of minimally invasive techniques, implants, and a reconsideration of intramedullary nailing.
