Comparative study in surgical management of fracture neck femur treated with Austin Moore prosthesis and bipolar prosthesis

Abstract

Introduction: It is a study of comparison of hemiarthroplasty with Austin Moore Prosthesis and bipolar. We wanted to know the efficacy of both the prosthesis. Hemiarthroplasty has been considered to be one of the gold standard modality in fracture neck femur management since years for elderly patients. Hemiarthroplasty provides better facilitation for the patients especially old age as the patients can be mobilised as early as 1st post op day as compared to internal fixation. Materials and Method: The study consist of 32 patients with fracture neck of femur. We have treated patients with Austin Moore Prosthesis and Bipolar Prosthesis. Clinical outcome and function results were evaluated by Harris Hip Score. Result: We have operated total 32 cases of fracture neck of femur. In which 16 cases were operated with Austin Moore Prosthesis and 16 patients were operated with Bipolar Prosthesis. We have achieved 87.5% of excellent to good result in Bipolar and 75% of excellent to good result in Austin Moore Prosthesis. Conclusion: It being a short term study the results of both the groups, i.e. group A (Austin Moore Prosthesis) and Group B (Bipolar prosthesis), are comparatively similar. And the notion that bipolar prosthesis after certain time behaves as a unipolar prosthesis turns out to be correct as supported by various studies in present study as well and thus the results of both the groups stands out to be more or less similar.
