<p class="abstract"><strong>Background:</strong> Hemi arthroplastyis a better option in treatment of fracture neck femur as it eliminates avascular necrosis of femoral head and non-union. It allows immediate weight bearing to return elderly patients to activity which helps in avoiding complications of recumbency and inactivity. The decision to perform hemi arthroplasty using a unipolar or bipolar prosthesis is a controversial issue. Both the prosthesis can be used even in remote areas both are cost effectives, good results can be achieved by general orthopaedic surgeons and post-operatively, it can be well adapted by Indian population. This study was done to compare the efficiency of Austin Moore’s prosthesis (AMP) and bipolar prosthesis for the management of intra capsular fracture neck femur in elderly patients.</p><p class="abstract"><strong>Methods:</strong> Patient’s above 60 years with fracture neck of femur were included. In all total 140 patients were randomly allocated for treatment by either AMP or bipolar prosthesis, in the department of Orthopaedics, IIMSR Medical College, Badnapur, Jalna between March 2014 to March 2017. The patients were followed up at 6 weeks, 12 weeks, 6 months and 1year. Functional outcome was assessed and compared with modified Harris hip score.<strong></strong></p><p class="abstract"><strong>Results:</strong> Modified Harris hip score was better with bipolar group as compared to AMP group. Functional activities like use of public transport were better with bipolar group. Complications like acetabular erosion were rare in bipolar group as comparison to AMP group.</p><p class="abstract"><strong>Conclusions:</strong> Fixed stem bipolar prosthesis is a superior option as compared to Austin Moore’s prosthesis.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
