Cemented versus uncemented hemiarthroplasty in elderly patients with displaced femoral neck fractures

Background: This study compared functional outcome and results between cemented and uncemented bipolar hemiarthroplasty in patients older than 60 years with displaced femoral neck fracture. Methods: Total fifty four patients with displaced femoral neck fracture were enrolled in this study. Out of total twenty eight patients underwent uncemented bipolar hemiarthroplasty and remaining twenty six patients underwent cemented bipolar hemiarthroplasty. Physical examination and radiographs were performed at the first and sixth months after operation and results were recorded. The patient’s pain and functions were evaluated with visual analogue scale and Harris Hip Score and then compared to each other. Results: All patients were followed up for at least 6 months. Mean operation and bleeding times were longer in cemented group compared to the uncemented group (p>0.05). The mean pain score was significantly less in the cemented group compared to the uncemented group (p=0.001). Hip functional outcome based on HHS was more in the cemented (p=0.001). The intraoperative and postoperative complication rate was higher in the uncemented group (p<0.05). Conclusions: Although higher rates of intraoperative bleeding and surgery time were seen with cemented bipolar hemiarthroplasty in older patients with femoral neck fracture compared to uncemented bipolar hemiarthroplasty, cemented bipolar hemiarthroplasty can cause less complication and improve patient’s function in less time.
