Percutaneous fixation of unstable proximal humeral fractures with cannulated screws.

Abstract

Proximal humeral fractures treated at level I trauma centers are typically displaced, unstable, high-energy injuries associated with injuries to other extremities and closed head injuries. One method that can be used to treat 2-part proximal humeral fractures, if the patient meets certain criteria, is closed reduction and percutaneous cannulated screw fixation. We conducted a retrospective review of 20 consecutive patients treated with this technique, and complete follow-up data were available for 14. Thirteen achieved union and functional range of motion at a mean of 10.5 weeks. Three experienced complications: failure of fixation, infection, and heterotopic ossification. The technique of closed reduction and percutaneous cannulated screw fixation is safe and effective for proximal humeral fractures in carefully selected patients.
