Prospective Study of the Functional Outcome of Bipolar Hemiarthroplasty Versus Total Hip Replacement in Elderly Patients With Fracture of the Neck of Femur by Using Harris Hip Score

Objectives: Prospectively study of the functional outcome of bipolar hemiarthroplasty (BHA) versus total hip replacement in elderly patients with fracture of the neck of the femur using Harris Hip Score (HHS). Methods: This prospective study was conducted in January 2020, in the Department of Orthopedics and Trauma Centre in J.A. Group of Hospitals, Gwalior (M.P.). 30 patients based on inclusion criteria, Garden type 3 and 4 intracapsular femoral neck fractures in the age group of 60 years and above, with independent ambulation before the injury and requirement of high functional demand activity to be treated with either BHA or THR. Functional assessment was made using HHSs at 14 day, 3 month, and 6 month, post-operatively. Results: This study shows the advantage of total hip arthroplasty (THA) in the recovery of hip function early. Six months after surgery, the Harris score of the THA group was higher than that of BHA group, and the excellent and good score in the THA group was also significantly higher than that in BHA group (p<0.001). Conclusion: THA compared to BHA gives a better functional outcome as evaluated by HHS at the end of 6 months in elderly patients with fracture of the neck of femur by using HHS.
