OSTEOSYNTHESIS OF PROXIMAL HUMERAL FRACTURES BY PHILOS PLATING



Abstract

Introduction- Proximal humeral fractures remain a challenging problem. Most authors agree that anatomical reduction and stable fixation are essential to allow early range of motion. A variety of techniques have been described such as threaded pins, tension band wiring, screws, nails, plates and primary prosthesis. Locking plates score over other implants by the virtue of providing greater angular stability and better biomechanical properties. The Aim of the Study is to evaluate the functional outcome of PHILOS plate Osteosynthesis of displaced proximal humeral fractures.

Materials and Methods- A retrospective study of 50 patients treated with PHILOS plating for the 2 part, 3part and 4 part proximal humeral fractures with a minimum follow up of 1 year. All the patients were assessed in clinic by Constant Murley and ASES scoring systems. X-ray evaluation was done for fracture healing, AVN, mal-union, non-union, collapse of head, screw penetration and impingement of plate.

Results- Total of 50 acute displaced fractures of proximal humerus treated with PHILOS plating between 2003–2005 were assessed. Mean age was 64 years (15–86) Male to female ratio was 12:38, dominant to non-dominant ratio was 32:18. According to Neer’s classification 16 fractures were 2 part, 24 fractures were 3 part and 10fractures were 4 part. The overall mean Constant score was 73.4(range20–100) and ASES score was 71.7(range 25–98). Under 60 years of age the mean Constant and ASES scores were 83.5 and 83, over 60 years of age scores were 63.1 and 60.4 respectively. The complications include two deep infections which needed excision arthroplasty, one malunion, one subacromial impingement which needed plate removal after fracture healing. No mechanical failure, no non-union, no ANV was noted.

Conclusions- PHILOS plate Osteosynthesis is a reliable method of treating complex proximal humeral fractures. It provides good mechanical stability and allows rapid mobilization with out compromising fracture healing.
