<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.

Background: Background: Fracture of the femoral neck has been reported with increasing incidence in recent times due to prevalence of osteoporosis. Uncemented HA coated modular bipolar hemiarthroplasty systems provide a customised press fit solution which improve the patient outcome with respect to limb length discreptancy. We report our series of 15 cases of fracture neck of femur operated over years with modular cementless HA bipolar hemiarthroplasty. Methods: 15 patients (age=50 to 70 years) with displaced femoral neck fractures were operated between January 2019 to December 2019. Cementless HA coated modular bipolar hemiarthroplasty using hydroxyapatite coated stem was done by single surgeon using same implant in all the patients through Moores approach. Clinical and radiological follow-up was done. Results: Total 15 cases with fracture neck femur were operated. The average follow up was 48 months. No intraoperative mortality was seen. 1 patient had calcar fracture of femur during canal preparation. 1 patient had delayed transient sciatic nerve palsy, and 1 patient had insignificant limb length discripency (0.5 cm). 12 patients reached to pre-injury status with average harris hip score of 88 at final follow up. Conclusions: Cementless bipolar hemiarthroplasty with hydroxyapatite coated stem is a good option for femoral neck fractures in elderly patients.
