Evaluation of functional outcome of femoral neck fractures treated with cemented modular bipolar hemiarthroplasty

Abstract

Introduction: Intracapsular femoral neck fractures account for about 50% of all hip fractures. With increase in life expectancy, the incidence is increasing. Popular treatment is replacement of femoral head by bipolar prosthesis. Materials & Methods: This study was done to assess the functional outcome of cemented bipolar hemiarthroplasty. Patients aged 50-80 years with intracapsular femoral neck fractures reporting to the orthopaedic department of the institute were considered for the study. 30 such patients were selected. All were operated by cemented modular bipolar hemiarthroplasty. It was a retrospective as well as prospective study. Regular clinical and radiological follow up was done for a minimum period of 6 months. Results were assessed using Harris Hip score. Results: Out of 30 patients assessed, 17 were females and 13 were males with average age of 68 years. At 6 months of follow up, out of 30 patients, excellent results were observed in 70% cases, good in 20% cases, average in 10% cases and poor in 0% cases. Conclusion: Most patients reported good to excellent functional results post cemented modular bipolar hemiarthroplasty. Hence, Cemented Modular Bipolar Hemiarthroplasty is a safe and effective treatment modality in treating femoral neck fractures in middle aged to elderly individuals.
