Abstract
Introduction: The fracture neck of femur is one of the most common fractures in the elderly. The time-tested unipolar prosthesis is being slowly replaced by bipolar prostheses, which are claimed to have a lower incidence of complications. In the last two decades, bipolar replacements of the femoral head have gained popularity for treating femoral neck fractures. This study was conducted to analyse the results of the surgical management of the fracture neck of femur using cemented modular bipolar hemiarthroplasty.Objective: To assess and analyse the results of the management of fracture neck of femur with cemented modular bipolar hemiarthroplasty.Methodology: The present study was a prospective study of 22 cases of fracture neck of femur admitted to Navodaya Hospital, attached to Navodaya Medical College, Raichur, between the study period of Sept 2019 to May 2021. Cases were selected according to inclusion and exclusion criteria, i.e., patients with intra-capsular fracture neck of femur above the age of 50 yrs. Medically unfit patients and patients not willing for surgery were excluded from the study. Follow up was done after 6 weeks and for further at 3 months, 6 months, 9 months, and 1 year.Results: In our series of 22 cases there were 7 males and 15 females, with a maximum age of 85 yrs, minimum age of 55yrs. There was a slight predominance of left sided fractures when compared to the right. The mean duration of hospital stay was 22 days. At the final one year follow up assessment with Harris Hip Score 8 patients (36.36) achieved 'Excellent' result, 11 patients (50%) achieved 'Good' result, 2 patients (9.09%) achieved 'fair' result and 1 patients (4.54%) achieved 'poor' result. In our series, at the end of final follow-up, there was no evidence of loosening, radiolucent zones, distal migration or subsidence of prosthesis.Conclusion: We conclude that bipolar cemented modular hemiarthroplasty produces good functional outcomes with minimal complications for displaced intracapsular femoral neck fractures and has several advantages; these results are comparable to the other studies. However long term results using cemented modular bipolar hemiarthroplasty needs further study for a longer period in a larger sample.
