Abstract: Aim: Evaluation of clinical and functional outcome of bipolar hemiarthroplasty in avascular necrosis of femoral head in adults. Materials and methods: In this prospective study 30 cases of avascular necrosis of femoral head were included and were treated with bipolar hemiarthroplasty and were mobilized on day 3 post operatively. Patients were followed up till 9 months post operatively at intervals of 1 month, 3 months, 6 months and 9 months. Results: The mean follow up was for 9 months. In our study, mean age of patients was 46.67 years (range 20- 80 years). In Present study total Harris hip score at the end of 6 months ranged from 46 to 95. Nine (30.0%) hemiarthroplasties had hip scores from 91 to 100 (excellent). Eleven (36.7%) had hip scores 81 to 90 (good).Seven hips (23.3%) were rated 71 to 80 (Fair) and Two (06.7%) were rated 24 to 69 (poor). Thus 90% of the hips were classified as having a fair to excellent results. Conclusion: Avascular necrosis of the hip joint predominantly affects a young to middle aged population. Given this epidemiological perspective arthroplasty is not the first choice treatment but young patients having healthy acetabulum and extensive collapse of femoral head, with joint subluxation, make it a viable primary alternative. Bipolar arthroplasty is a simple, reliable, viable and a cost effective procedure as a primary surgical treatment modality in the patients with avascular necrosis of the hip joint.
