“…In another study by Marcus, R et al [23], where the two types of prosthesis were compared it was noted that functional results of bipolar prosthesis were not significantly better than Austin Moore prosthesis. This observation is different from that was found in many studies comparing unipolar and bipolar prosthesis.…”

Introduction: Fracture neck of femur is one of the widely occurring hip fractures among elderly people in India. They greatly affect the quality of life in patients, and 30% mortality is observed in these fractures. This study was carried out to study the profile of fracture neck of femur presenting to a tertiary care teaching hospital. The study also assessed functional outcome differences between Austin Moore and bipolar hip prosthesis used in hemiarthroplasty. Methods: The present prospective study includes 50 cases of intracapsular fracture neck of femur in elderly patients above the age of 55 years irrespective of sex treated by hemiarthroplasty using unipolar (Austin Moore's) or bipolar(nonmodular) endoprosthesis followed up for 6 months. After surgery, all the cases were followed up. The functional results after hemiarthroplasty were analyzed using Harris Hip Score (HHS). Results: The mean age was 63.14±5.66 in AMP, and it was 63.29±4 in bipolar prosthesis. The other baseline parameters were comparable between the groups. The mean Harris hip score was 83.19±10.94 in AMP, and it was 84.62±9.53 in bipolar prosthesis. The difference was statistically not significant (P value 0.654). A higher percentage of patients, about 43% were found to have good functional outcome with bipolar prosthesis than those with Austin Moore prosthesis whose percentage having fair outcome was found to be 19%. However, no significant difference was seen between the groups. Conclusion: Treatment outcomes were similar between the two groups.

“…The elderly females are more prone to fracture neck of femur [5,6] . [8] : 91.4%; Mukherjee and Puri (1986): 58.3%; Amte and Sanchetti (1987): 55%; Bavadekar and Manelkar (1987): 60.9%.Male femoral neck fracture patients are in general younger than female patients.…”

“…Advantages of the unipolar prosthesis include lower cost and no risk of polyethylene wear debris. Proposed advantages of the bipolar prosthesis include less acetabular wear and potentially less hip/groin pain [5] . The choice between unipolar and bipolar prostheses is less clear.…”

“…The main theoretical advantage of a bipolar over a unipolar prosthesis is the reduction of acetabular erosion due to movement taking place within the implant rather than between the head of the prosthesis and the acetabulum, although there is variation in the comparative distribution of the movement. Movement within the prosthesis may also reduce the pain caused by the prosthesis moving against the acetabulum [5] .…”

Background and Objective: Femoral neck fractures have been considered 'unsolvable fracture' in the olden era of orthopaedics due to high rate of associated complications, which include nonunion and avascular necrosis of the femoral head. Prosthetic replacement as a primary procedure eliminates osteonecrosis and non union as complications of femoral fractures and also allows immediate weight bearing to return elderly patients to activity and help avoid complications of recumbency and inactivity. 2 The decision to perform hemi arthroplasty using a unipolar or bipolar prosthesis remains controversial, with proponents on either side. So, in view of varied opinions we desire to compare the efficiency of these two prosthesis unipolar and bipolar prosthesis for the management of intra capsular fracture neck femur in elderly. Methods: 112 patients above 60 years and an acute displaced fracture of the femoral neck were randomly allocated to treatment by either AMP or bipolar HA, in the department of Orthopaedics, AIMS BG Nagara between May 2013 to May 2016.The patients were followed up at 6weeks, 12 weeks, 6 months and 1year. Functional outcome was assessed and compared with Harris hip score and radiological parameters Results: The two groups of patients with mean age of 70.4 in AMP group and 69.1 in Biploar group did not differ in their pre-injury characteristics (sex, fracture pattern, comorbidity, mode of injury and preinjury ambulatory status) and perioperative parameters such as duration of operation, blood loss, hospital stay and mortality. The mean Harris hip score in Bipolar and AMP group was 90.03 and 84.4, respectively. Functional activities like use of public transport was better with bipolar group. Incidence of complications like Superficial infection, haematoma and acetabular erosion was encountered in AMP group. Conclusion:The use of a bipolar endoprosthesis in the management of displaced femoral neck fractures in the elderly was associated with better mean Harris hip score and incidence of complications was limited. Hence, bipolar would be a better option in elderly patients with fracture neck of femur. Moreover the cost difference between AMP and Bipolar prosthesis is not much in our country.
