A study on functional outcome of bipolar hemiarthroplasty in fracture neck of femur

Abstract

Introduction: Neck of femur fractures are commonly seen in the elderly age group. They are mostly seen in patients above 60 years of age. Materials and Method: Our aim is to assess the functional outcome of bipolar hemiarthroplasty in elderly aged patients. 20 patients above 60 years of age, with fracture of femoral neck, were included in this study. They were treated with either cemented or uncemented bipolar hemiarthroplasty. The clinical and radiological follow-up was done for a minimum period of 12 months. The results were assessed using Modified–Harris Hip Score (HHS). Results: Total of 20 patients, in which 12 males and 8 females with an average age of 62 years, were 9 patients had associated co-morbidities. After 12 months of follow-up using Modified HHS, 13 had excellent results, 6 had good results, 1 had a fair result and no poor results were seen. The mean Modified Harris hip score was 89.5. There was no mortality and one patient was lost to follow up. There were no acetabular erosion, acetabular protrusion, or heterotopic ossification recorded in any of the patient during the follow-up. Conclusion: All the patients had a satisfactory functional outcome. To conclude, the bipolar prosthesis is a safe modality in treating femoral neck fractures in elderly patients with good functional outcomes.
