Abstract：BACKGROUND:Artificial femoral head replacement is an effective measure for displaced femoral neck fracture in the elderly, but the bone mass is poor in these patients. There is a controversy in the selection of bone cement or cementless femoral prosthesis. <br> OBJECTIVE:To compare the clinical efficacy of bone cement and cementless femoral prosthesis in elderly patients with displaced femoral neck fracture. <br> METHODS:From January 2011 to December 2012, 26 hips with displaced femoral neck fracture were treated with cement hemi-hip arthroplasy and 30 hips were treated with cementless femoral implants. Surgery time, intraoperative bleeding, postoperative drainage, postoperative complications were compared between the two groups. Hip function was evaluated according to Harris hip score system. <br> RESULTS AND CONCLUSION:Al patients were fol owed up for 20-44 months. The clinical results were satisfied. At 12 months after replacement, excel ent-to-good rate of cement group and cementless group was 89%and 83%, respectively according to Harris hip score evaluation with no significant differences. There were no statistic difference between two groups in intraoperative blood loss and postoperative drainage, but operative time in cement group was longer than in cementless group (P<0.01). There was no prosthesis loosening, subsidence, infection or joint dislocation during fol ow-up in both groups. These findings suggested that cementless prosthesis hemi-hip replacement can get good clinical results as cement prosthesis replacement for treatment of displaced femoral neck fracture in elderly patients.
