Fracture neck of femur are one of the most common fractures in elderly population following a trivial trauma. The goal of treatment of these fractures is restoration of pre fracture function without associated morbidity, in earliest possible time Earlier hemiarthroplasty by using Vitallium or stainless steel was popular, practiced by Austin Moore's method which produced fairly good results. But it had its limitations in loosening and reactions at acetabulum among others. Many of the shortcomings of this procedure was overcome by a new type of prosthesis, which had the great advantage of second joint, below the acetabulum. It was named as bipolar prosthesis, since it had an outer head of metal which is stationary and this articulates with acetabulum and a second inner small metallic head articulates with the high density polyethylene (HDPE) lining the inner surface of the outer head. This prosthesis proved very useful and results are encouraging. The aim of the study is to assess the functional outcome of Bipolar prosthesis in Intracapsular fracture neck of femur.
MATERIALS AND METHODS
This study was done in 20 patients with fracture neck of femur in government general hospital Kurnool over a period of 2 years, All of them were managed by bipolar hemiarthroplasty through posterior approach. All patients were followed up for 6 months, results were evaluated with Harris Hip Score.
85% of the patients had an excellent to good Harris Hip Score while 10% of the patients had a fair result and 5% had a poor result.
Bipolar hemiarthroplasty provides early mobilization, good relief of pain and good level of activities with minimal complications.
