Functional Outcome of Bipolar Prosthesis versus Total Hip Replacement in the Treatment of Femoral Neck Fracture in Elderly Patients.

INTRODUCTION: The present study was performed to compare cemented total hip replacement (THR) with cemented bipolar prosthesis in the treatment of displaced fracture neck of femur in elderly patients.

MATERIALS AND METHODS: This prospective study included 47 patients of greater than 60 years of age and having fracture of neck of femur, out of which 25 patients were managed by cemented bipolar prosthesis and remaining 22 were managed by cemented THR between June 2011 and June 2013. These patients were followed up post-operatively for two years, at 6, 12 and 24 months, for functional analysis using Modified Harris Hip Score.

RESULTS: Modified Harris Hip Score was significantly higher in the THR group as compared to the bipolar prosthesis group at 6, 12 and 24 months post-operatively. Pain was almost similar in both the groups at all follow-up periods. Gait and range of motion was significantly higher in THR group as compared to bipolar prosthesis group at all-time point intervals.

CONCLUSION: Cemented THR is a better option as compared to cemented bipolar prosthesis based on our short term functional outcome for the management of fracture of neck of femur in elderly patients.
