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

OBJECTIVE This study compared functional outcomes and preoperative between cemented and uncemented bipolar hemiarthroplasty in patients older than 65 years with subcapital displaced femoral neck fracture. METHODS Fifty one patients with displaced femoral neck fracture were enrolled in this study. Twenty nine patients underwent uncemented bipolar hemiarthroplasty and 22 underwent cemented bipolar hemiarthroplasty. Physical examination and radiographs were performed at the first and sixth months after operation and results were recorded. The patients' pain and function were measured with Visual analogue Scale and with Harris Hip Score (HHS), respectively and then compared with each other. RESULTS The mean duration of follow up was 18.9 and 19.5 months in the cemented and uncemented groups, respectively. All patients were followed up for at least 6 months. Mean operation and bleeding times were longer in the 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 group (P= 0.001). The intraoperative and postoperative complication rate was higher in the uncemented group (P<0.05). CONCLUSION 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 complications and improve patients' function in less time.
