Minimally Invasive Fixation for Proximal Humeral Fracture: A Review on the use of T2 Proximal Humeral Nail

Abstract

Objective and methodology A retrospective review of the outcome of patients who had proximal humeral fracture treated with T2 Proximal Humeral Nail from January 2007 to March 2011 was conducted. The demographics, union rate, and complications were reviewed. The patient outcome was assessed with the American Shoulder and Elbow Surgeons (ASES) score and Constant-Murley score. Results Thirty-two cases of traumatic proximal humeral fractures were included. The average follow-up period was 14.7 months. All fractures healed with an average of 3.97 months. The average forward flexion and lateral abduction of shoulder was 132° and 123°, respectively. The postoperative average Constant-Murley score was 67 (48-80) and ASES score was 82.9 (73-100). There was one case of avascular necrosis of humeral head. Six cases of minor screw complications required removal of screws later. No wound infection or neurovascular injury was found. Discussion and conclusion With the proper surgical technique high union rate, good functional recovery, and low complication rate can be achieved by using T2 Proximal Humeral Nail in managing traumatic proximal humeral fracture.
