Abstract

• PURPOSE: This is a retrospective study to analyze the functional results of closed reduction and percutaneous fixation of displaced unstable proximal humerus fractures. MATERIALS AND METHODS: We report 23 patients, 20 with 2-part and 3 with 3-part proximal humerus fractures that can be reduced closed but remain unstable in which percutaneous fixation was performed. The fixation methods were multiple pinning in 10, multiple cannulated screw fixation in 8, Rush pin fixation in 3 and Rush pin combined with other methods in 2. The functional rusults were analyzed with Neer,scriteria. RESULTS: The functional rusults were excellent in 14, satisfactory in 4 and unsatisfactory in 5. No significant difference was not noted in the long term follow-up results according to the fixation methods but Rush pin resulted in impingement and displacement of greater tuberosity. CONCLUSION: Closed reduction and percutaneous fixation is a useful alternative to open reduction and internal fixation for the displaced 2-part or 3-part proximal humerus fractures that can be reduced closed but remain unstable.
