Study of the immediate short term clinical and radiological outcome of intertrochanteric neck of femur fractures treated with primary bipolar hemiarthroplasty in geriatric population in a tertiary care centre

Abstract

<p class="abstract"><strong>Background:</strong> Intertrochanteric fracture in elderly patient is a frequent problem and is becoming more common as the proportion of elderly people in the population increases. Unstable intertrochanteric fracture in the elderly patient is associated with a high rate of mortality as much as 20 percent during the first postoperative year. The treatment of such unstable intertrochanteric fracture is still controversial. So as to allow for earlier postoperative weight-bearing, primary hemiarthroplasty was proposed by some authors. The purpose of this study is to evaluate the functional and clinical outcomes of cemented bipolar arthroplasty as a primary treatment for unstable intertrochanteric fracture in the elderly patient.</p><p class="abstract"><strong>Methods:</strong> It was an observational retrospective plus prospective study design over a period of 18 months in a tertiary care setting with a sample size of 41. Patients fulfilling the inclusion criteria were assessed clinically using Harris hip score and radiologically were operated for bipolar hemiarthroplasty. They were assessed intraoperatively, immediate postoperatively and after 4 weeks for functional outcome using Harris hip score and assessed radiologically. Patients were also be evaluated for intraoperative and postoperative complications if any. The outcome was analysed statistically to comment on functional outcome of bipolar hemiarthroplasty.<strong></strong></p><p class="abstract"><strong>Results:</strong> In our study majority of the patients 70% (29) had excellent and good outcomes at the end of 1 month. Out of the rest 22% more had fair outcome at the end of month. Thus 93% patients had favorable outcomes at the end of 1 month while 7% (3 cases) had poor outcome when measured using Harris hip score.</p><p class="abstract"><strong>Conclusions:</strong> Primary cemented bipolar hemiarthroplasty is a viable option that leads to good functional outcomes and allows early mobilization and weight bearing.</p>
