Four Part Fractures of the Proximal Humerus

BACKGROUND: Four part fractures of the proximal humerus represent approximately 5% of all proximal humeral fractures. Treatment options for these displaced fractures include nonoperative treatment, open reduction and internal fixation, and arthroplasty. Presently, there is a lack of consensus on the optimal management strategy for this complex injury. OBJECTIVE: To determine the effect of alternate devices in the management of four part proximal humerus fractures in patients on the risks of reoperation, need for implant removal at 1 year, and pain.
