Arthroscopically Assisted Open Reduction and Internal Fixation of Proximal Humerus Fractures

Fractures of the proximal humerus are relatively common and account for 4-5% of all fractures (1-3). The vast majority of these fractures (85%) are minimally displaced and are adequately managed nonoperatively with immobilization followed by early motion. The remaining 15% of these fractures are displaced. The functional outcome of treating displaced fractures nonoperatively is suboptimal, and some form of reduction and fixation is indicated (1,4). However, there is considerable disagreement with regard to classification of these fractures, the indications for surgical management, the surgical approach, and the method of fixation.
