AbstractFractures of the proximal humerus are common and the treatment for both displaced and comminuted variants remains controversial. Treatment options initially consisted of closed reduction, traction, casting, and abduction splints. In the early 1930s, operative treatment for displaced fractures gained popularity, which continued in the 1940s and 1950s. Humeral head replacement for severely displaced fractures of the proximal humerus was introduced in the 1950s. In the 1970s, the Association for Osteosynthesis/Association for the Study of Internal Fixation popularized plates and screws for fracture fixation, and humeral head prostheses were redesigned. The traditional management of severely displaced proximal humerus fractures has been with arthroplasty because of the significant risk of osteonecrosis of the humeral head following open reduction and internal fixation. The authors present a case of a 51-year-old right-hand-dominant man who sustained a seizure along with a posteriorly displaced proximal humerus fracture-dislocation of the right upper extremity. This was treated with surgical extrusion of the entire humeral head and subsequent open reduction and internal fixation. During the surgical procedure, the patient's humeral head was completely extruded from the body through a posterior incision and then reduced back to the proximal humerus through the standard anterior deltopectoral approach. After 4 years of follow-up, the patient remains pain free, has functional range of motion, and is without signs of osteonecrosis on plain radiographs. This case illustrates that even with complete disruption of the vascular supply to the humeral head, revascularization after osteosynthesis is possible. [Orthopedics. 2016; 39(4):e779-e782.].
