Outcome of cemented hemiarthroplasty of hip in elderly patients operated for neck of femur fracture

Abstract

Introduction: Femoral neck fractures are a common entity in elderly patients. This commonly occurs following trivial injury and the insult is compounded by osteoporosis in this age group. Cemented hemiarthroplasty is recommended by several studies and by several registries, due to low comorbidities compared to uncemented hemiarthroplasty. Significantly improved mobility scores, low pain scores make this a treatment of choice. Materials and Methods: This study included 108 patients who presented with fracture neck of the femur with an average age of 68.30 years and were operated with hemiarthroplasty by two consultant orthopedic surgeons in a standard operative setting over 5 years with modular bipolar prosthesis using lateral approach (Hardinge approach). Patients on follow-up were evaluated using Oxford Hip Score and Forgotten Joint Score. Results: The mean Oxford Hip Score was 39.46 suggestive of satisfactory joint function which may not require any further treatment. The mean Forgotten Joint Score was 83.46 suggestive of high degree of forgetting artificial joint. Conclusion: A very high Oxford Hip Scores and very high Forgotten Joint Scores after surgery suggests that the patients have retained or regained their independence and are doing good. This goes on to suggest that in spite of advancements in surgical techniques and implants for osteosynthesis, hemiarthroplasty done in indicated cases gives a good functional outcome and a lasting solution for these fractures.
