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 pre-injury 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.
