Background: The number of femoral neck fractures increases with advancing age. Surgery is the mainstay of treatment for displaced fractures of neck of femur, hemiarthroplasty being a common operative procedure in elderly patients. The main objective of treatment in the elderly active individual is early restoration of premorbid walking state. Materials and Methods: A prospective study with 30 cases were selected according to inclusion and exclusion criteria and treated by modular bipolar prosthesis. Results: In our series of 30 cases there were 13 males and 17 females, with a maximum age of 85 yrs, minimum age of 62 years and an average age of 73 years. 10% of patients had Garden type ll fracture 30% of them had a Garden type III fracture radiologically, while 60% had a Garden type IV. Patients were discharged at two weeks after suture removal. At the final one year follow up assessment with Harris Hip Score 11 patients (36.6%) achieved 'Excellent' result, 14 patients (46.6%) achieved 'Good' result, 3 patients (10%) achieved 'fair' result and 2 patients (6.6%) achieved 'poor' result. Overall, 83% of the patients achieved an excellent or good result. Conclusion: Femoral neck fractures treated by modular bipolar prosthesis ensues better range of movement, freedom from pain and early recovery to unassisted activity with an acceptable complication rate. Variable sized stem, shells gives advantage of exact matching of head.
