The purpose of this study was to evaluate the clinical results of treatment for proximal humerus fractures using PHILOS, which can provide angular stability using a locking mechanism.
We treated 18 patients (5 men and 13 women, mean age 65 years) between 2006 and 2009. The mean follow-up period was 9.5 months. Fracture type by the AO classification was 11-A2 in 3 cases, 11-A3 in 2, 11-B1 in 2, 11-B2 in 5, 11-C1 in 2, and 11-C2 in 4. The fractures united in 17 patients, but in one patient the distal screw broke and back out after the operation. There were no cases of infection or head necrosis. Varus deformity occurred in two cases postoperatively. The mean JOA score was 84 points.
We conclude that PHILOS is a good tool for treatment of humeral fractures, although the risk of implant-related complication must be borne in mind.
