UNIPOLAR VERSUS BIPOLAR HEMIARTHROPLASTY IN ELDERLY PATIENTS WITH FRACTURE NECK OF FEMUR

Abstract

Background/Purpose: Hemiarthroplasty is the treatment of choice n neck of femur fractures in elderly patients. Unipolar and bipolar prostheses have their own advantages and disadvantages, creating confusion in which prothesis to use. 40 elderly patients (>65 years age) with intracaps Methods: ular neck of femur fractures were included and randomly divided equally in this study, 20 patients were treated with unipolar hemiarthroplasty and 20 patients with bipolar hemiarthroplasty. All patients were evaluated for functional outcome by using Harris Hip score and radiological outcomes using various parameters. The outcomes of both groups were then compared using Chi-square test. Results: Overall mean Harris hip score pre operatively for unipolar hemiarthroplasty was 36.2 and bipolar hemiarthroplasty was 39.1 which increased to 81.8 for unipolar and 85.05 for bipolar hemiarthroplasty respectively, with p-value of <0.561. Our results also shows that we have 35% excellent result in Bipolar whereas we have 15% excellent result in unipolar Hemiarthroplasty group. The results of our study shows that uncemented bipolar hemiarthroplasty Conclusion: gave better results when compared with uncemented unipolar hemiartheoplasty. Our results also shows that, cemented bipolar hemiarthroplasty gave better results when compared with cemented unipolar hemiarthroplasty clinically and radiologically. Thus, Bipolar hemiarthroplasty did better when compared with unipolar hemiarthroplasty in general
