• ABSTRACT
    • The management of three- and four-part proximal humerus fractures remains controversial because the literature has supported all forms of management, including nonsurgical management, open reduction and internal fixation (ORIF), and shoulder arthroplasty. Specific patient factors ultimately influence the decision of which treatment best fits the patient and the fracture. Surgeons should understand the rationale for nonsurgical and surgical management of these fractures, including ORIF and reverse shoulder arthroplasty.
