Study of Fracture Neck Femur Treated with Cemented Bipolar Prosthesis vs. Austin Moore Prosthesis in Elderly

Abstract

Introduction Intracapsular femoral neck fractures are common in the elderly population. Replacement arthroplasty is now the established modality of treatment in fracture of femoral neck in the elderly due to reasons like failure of internal fixation, high rate of nonunion and avascular necrosis, poor hold of implant in internal fixation due to osteoporosis, pulmonary complications and deep vein thrombosis. This is a prospective study and results are short term. Outcomes were analysed by Harris Hip scoring system and radiographs taken during follow up.

Aim and Objectives To analyse the results of Hemi arthroplasty with bipolar or Austin Moore prosthesis using Harris Hip score and determine the ideal prosthesis for study group.To study the morbidity and mortality rate and associated complications with the procedure.

Materials and Methods This prospective study included 60 patients who are more than 60 years of age of both sexes. Intracapsular neck femur fracture where randomly allocated.

Results It showed excellent results in 93.33% of bipolar group of patients as compared to 73.33% of Austin Moore group of patients with p value 0.05 which is significant and thus bipolar group patients have significantly higher scores as compared to Austin Moore group patients.

Conclusion Results of bipolar prosthesis seems to be better compared to Austin Moore prosthesis.
