Evaluation of functional outcome of cemented bipolar hemiarthroplasty for treatment of osteoporotic proximal femoral fractures in elderly people

Abstract

Background: In India the estimated geriatric population is going to rise from 8% of total population in 2010 to 19% by 2050. Incidence of osteoporosis and associated fractures will rise in coming years with increasing elderly population. Management of fracture neck of femur and unstable intertrochanteric fractures in osteoporotic bone is challenging in elderly as they are more prone for fracture associated complications like pressure sore, deep vein thrombosis and pneumonia. Aim: The purpose of this study is to evaluate the role of cemented bipolar hemiarthroplasty in management of osteoporotic proximal femoral fractures in elderly people. Patients and Methods: In this prospective study twenty patients with osteoporosis having proximal femoral fractures (fracture neck of femur/unstable intertrochanteric fracture) were treated by cemented bipolar hemiarthroplasty. Patients were followed up at 3 weeks, 3, 6, and 12 months to evaluate the function outcome. Mean age of the patients in this study was 73.84 years. Results: Average duration follow up in this study was 14.63 month. Mean Harris Hip Score in the postoperative period was 42.73 ± 8.78 which improved to 81.57 ± 9.11 at 6 months. Average post-operative mobilization duration was 3.84 day and average hospital stay was 11.31 day. At 1 year follow up 85% patients had excellent to fair outcome and 10% had poor outcome. Conclusion: Treatment of osteoporotic proximal femoral fractures with cemented bipolar hemiarthroplasty gives better functional outcome.
