Proximal Humerus Fractures: How to Achieve Best Outcomes

The treatment of proximal humerus fractures remains controversial. Although treatment modalities may vary, the goal of obtaining the best outcomes for patients remains the same. Most proximal humerus fractures can be treated nonsurgically but should still be managed actively. Deciding on surgical management requires a good understanding of indications and options. Indications for open reduction and internal fixation include younger or active patients with displaced two-, three-, and four-part fractures as well as fracture-dislocations with head-split patterns. Obtaining ideal outcomes requires anatomic reduction with restoration of the medial calcar as well as optimal position of implants to favor biomechanical stability. Reverse total shoulder arthroplasty is indicated for patients with severe and displaced fractures in older or low-demand patients. Obtaining the best functional outcomes depends on implant position, tuberosity healing, and early surgical intervention. Regardless of the treatment modality, these fractures can be challenging, and proper patient rehabilitation must be implemented. Future research will focus on patient selection and improving surgical techniques to maximize outcomes.
