Functional outcome of bipolar hemiarthroplasty in fracture neck of femur

Abstract

Introduction: Femoral neck fractures occur most commonly in elderly females. They are common in patients above 60 years of age. Materials and method: We undertook this study to assess the functional outcome of bipolar hemiarthroplasty. 30 patients above 60 years of age, with intra-capsular fracture neck of femur were undertaken for the study. They were operated with either cemented bipolar hemiarthroplasty. The clinical and radiological follow-up was done for a minimum period of 6 months. The results were assessed using Harris hip score – modified (HHS). Results: Out of 30 patients, 18 were females and 12 were males with an average age of 64 years. 14 patients had associated co-morbidities. After 6 months of follow-up using HHS, 14 had excellent results, 12 had good results, 1 had fair results and poor results were observed in 1 patient. The mean Harris hip score was 88.5. There was one mortality and one patient was lost to follow up. There was no stem subsidence, acetabular erosion, acetabular protrusion, or heterotopic ossification in any of the patients during the follow-up period. Conclusion: All the patients had satisfactory functional outcome. To conclude, bipolar prosthesis is a safe option in treating fracture neck of femur in the elderly with good recovery in-spite of having several co-morbidities.
