Cemented vs uncemented bipolar hemiarthroplasty in neck of femur fractures: A case series of 90 patients

Introduction: The purpose of our study was to compare results of cemented vs cementless bipolar hemiarthroplasty in fractures of neck of femur with regards to functional outcome, operative time, pain, blood loss and complications.Materials and Methods: Ninety patients with displaced femoral neck fracture operated with bipolar hemiarthroplasty were enrolled in this study and their medical records were reviewed. 35 patients had undergone uncemented bipolar hemiarthroplasty and 55 had undergone cemented bipolar hemiarthroplasty. Post-operative status of the patients was assessed using Harris Hip Score (HHP) and Visual Analogue Score (VAS). Patients were reviewed after one year of surgery at 6 wks interval. Results: Mean operation and bleeding times were longer in the cemented group compared to the uncemented group. The mean pain score was significantly less in the cemented group compared to the uncemented group. Hip functional outcome based on HHS was more in the cemented group. The intraoperative and postoperative complication rate was higher in the uncemented group.Conclusion: Although higher rates of intraoperative bleeding and longer surgery time were seen with cemented bipolar hemiarthroplasty in patients with femoral neck fracture compared to uncemented bipolar hemiarthroplasty, cemented bipolar hemiarthroplasty is better because of better functional outcome and less residual pain.
