Unstable Intertrochanteric Femur Fracture in Elderly Treated with Bipolar Hemiarthroplasty Versus Dynamic Hip Screw - A Prospective Comparative Study

Abstract

Introduction: Intertrochanteric fractures are one of the most common fractures in elderly population and have a huge impact on the health care system of the society. Objectives: The objective of our study was to compare functional outcome and complication rates of bipolar hemiarthroplasty to dynamic hip screw which is a established procedure for unstable intertrochanteric fracture femur. Materials and Methods: The present study included 50 patients over the age of 55 years, 25 undergoing bipolar hemiarthroplasty and 25 undergoing dynamic hip screw for unstable intertrochanteric fracture femur and their functional outcomes were compared with Harris hip score. Results: We found that the average Harris hip score was better for the bipolar hemiarthroplasty group than for the dynamic hip screw group at 6 months. Conclusion: Bipolar hemiarthroplasty is an effective alternative to dynamic hip screw for unstable intertrochanteric fractures in elderly patients as it has a good function outcome and lower complication rate. A larger randomized control trial has to be conducted to arrive at a conclusion.
