BACKGROUND
Introduction of new bone cements into clinical practice should include radiostereometric studies.
MATERIALS AND METHODS
A prospective randomised radiostereometric study was performed, comparing SmartSet HV and Palacos R acrylic bone cements (without antibiotics) using third-generation cementing techniques in primary total hip arthroplasty. Thirty-five patients (36 hips) undergoing Charnley total hip arthroplasty were randomised to receive either of the two cements and were followed with repeated clinical, radiographic and radiostereometric examinations over 24 months. Twenty-seven patients (28 hips) attended 2 years postoperatively.
RESULTS
The mean distal translation observed was -0.15 mm for SmartSet HV and -0.16 mm for Palacos R. The mean rotation around the longitudinal axis was 0.9 degrees for SmartSet HV and 1.2 degrees for Palacos R. The Merle d'Aubigne Postel score was the maximum of 18 points for all patients in both groups.
CONCLUSIONS
No statistically significant difference in stem fixation with use of SmartSet HV and Palacos R was found at 2-year follow-up.
背景
新型骨水泥引入临床应用应包括放射立体测量研究。
材料与方法
进行了一项前瞻性随机放射立体测量研究，在初次全髋关节置换术中采用第三代骨水泥技术，比较SmartSet HV和Palacos R丙烯酸骨水泥（不含抗生素）。35例（36髋）接受Charnley全髋关节置换术的患者被随机分配接受两种骨水泥中的一种，并在24个月内进行了重复的临床、影像学和放射立体测量检查。27例（28髋）患者术后2年进行了随访。
结果
SmartSet HV观察到的平均远端移位为-0.15 mm，Palacos R为-0.16 mm。SmartSet HV绕纵轴的平均旋转角度为0.9度，Palacos R为1.2度。两组所有患者的Merle d'Aubigne Postel评分均为最高18分。
结论
在2年随访时，使用SmartSet HV和Palacos R进行假体柄固定未发现统计学上的显著差异
