COMPARATIVE STUDY OF HEMIREPLACEMENT ARTHROPLASTY WITH BIPOLAR PROSTHETIC AND PROXIMAL FEMORAL NAIL (PFN) IN UNSTABLE INTERTROCHANTERIC FRACTURE OF FEMURE: INTERVENTIONAL PROSPECTIVE RANDOMIZED STUDY

Abstract

Background: Intertrochanteric femur fracture incidence has increased due to increased life expectancy and osteoporosis. Management of these fractures in elderly is challenging due to difficult anatomical reduction, poor bone quality and osteoporosis. Internal fixation in these cases usually involves prolonged bed rest to prevent implant failure which leads higher complication such as deep vein thrombosis, pneumonia pulmonary embolism, bed sores, increased morbidity.

Methods: The present study was prospectively carried out in 60 consecutive patients of Fracture Intertrochanter Femur and treated with Hemiarthroplasty with Cemented Bipolar Prosthesis and Proximal Femoral Nail.

Results: The average harris hip score in PFN group is 88.21±4.36 and in Bipolar group is 85.21±8.12. Final functional outcome were better in PFN group (P value 0.02) than by Bipolar group and significant.

Conclusion: The outcomes of the stable fractures treated with either Bipolar or PFN were similar. Unstable comminuted fractures treated with Bipolar showed significantly better outcomes with all patients having good results.
