A comparative study of functional outcome of fracture neck femur treated with cemented bipolar and bipolar with femoral head as a bone graft

Abstract

Introduction: The advantages and limitations of cementing and uncementing during hemiarthoplasty for the fracture neck of femur in elderly patients, is a matter of debate. Though cementing gives good initial fix, it has the risk of bone intraoperative hypotension. On the other hand uncemented implants are associated with periprosthetic fractures and are expensive. Femoral head can be use as source of autologous bone graft to fill the medullary cavity of femur, thus reducing the complications associated with cemented bipolar hemiarthoplasty. Aim: To do a comparative study of functional outcome of fracture neck femur treated with cemented bipolar hemiarthoplasty and bipolar hemiarthroplasty with femoral head as a bone graft. Methods: This study was a prospective study which was conducted in tertiary care hospitals in Mangalore from the year 2018-2020. Patients with fracture neck femur were included in study. Patients were divided into 2 groups having 15 patients each. Group A which underwent bipolar hemiarthroplasty with femoral head as a bone graft and Group B which underwent cemented bipolar hemiarthroplasty. Functional outcome was compared between the two groups. Results: At the end of one year in the Bone Graft group 11 patients (73.3%) had excellent results; 4 patients (26.6%) had good results; whereas in the cemented group 5 patients (33.3%) had excellent results; 5 patients (33.3%) had good results; 4 patients (26.6 %) had fair results, 1 patient (6.6%) had a poor result. The result was significant (p value
