We report the long-term outcome of a modified second-generation cementing technique for fixation of the acetabular component of total hip replacement. An earlier report has shown the superiority of this technique assessed by improved survival compared with first-generation cementing. The acetabular preparation involved reaming only to the subchondral plate, followed by impaction of the bone in the anchorage holes. Between 1978 and 1993, 287 total hip replacements were undertaken in 244 patients with a mean age of 65.3 years (21 to 90) using a hemispherical Weber acetabular component with this modified technique for cementing and a cemented femoral component. The survival with acetabular revision for aseptic loosening as the endpoint was 99.1% (95% confidence interval 97.9 to 100 after ten years and 85.5% (95% confidence interval 74.7 to 96.2) at 20 years. Apart from contributing to a long-lasting fixation of the component, this technique also preserved bone, facilitating revision surgery when necessary.
我们报告了一种改良的第二代骨水泥技术用于全髋关节置换髋臼组件固定的长期结果。一份较早的报告显示，与第一代骨水泥技术相比，通过提高生存率评估，该技术具有优越性。髋臼准备工作包括仅扩髓至软骨下骨板，随后在锚固孔中进行骨打压。1978年至1993年期间，对244例平均年龄65.3岁（21至90岁）的患者进行了287例全髋关节置换，使用半球形韦伯髋臼组件，采用这种改良的骨水泥技术以及骨水泥固定的股骨组件。以无菌性松动翻修髋臼作为终点指标，10年后的生存率为99.1%（95%置信区间97.9至100），20年后为85.5%（95%置信区间74.7至96.2）。除了有助于组件的长期固定外，该技术还保留了骨量，便于必要时进行翻修手术。
