Philos Plate Fixation for Displaced Proximal Humeral Fractures

Abstract

Purpose.

To evaluate the treatment outcome of Philos plate fixation for displaced proximal humeral fractures in 27 consecutive patients.

Methods.

6 men and 21 women aged 22 to 85 (mean, 56) years underwent Philos plate fixation for displaced proximal humeral fractures. 11 patients were aged ≤60 years and 16 >60 years. All fractures were closed with no associated injuries and classified as 2-part (n=13), 3-part (n=12), and 4-part (n=2), according to the Neer classification. Patients were assessed radiologically and functionally using the Constant shoulder score.

Results.

Patients were followed up for 6 to 24 (mean, 13) months. All the fractures united except in a 76-year-old woman with a 3-part fracture in whom there was fracture collapse and screw penetration of the humeral head at 6 weeks. She subsequently developed non-union and avascular necrosis. The mean Constant shoulder score was 70 (range, 28–88). 11 patients had a score exceeding 75, 13 were scored between 50 and 75, and 3 were below 50.

Conclusion.

Philos plate fixation provided stable fixation, minimal metal work problems and enabled early range-of-motion exercises to achieve acceptable functional results.
