BMJ:不同全髋关节置换植入体材料对术后翻修率和髋关节功能的影响

2017-11-06 zhangfan MedSci原创

研究认为,对于初次全髋关节置换患者,传统的金属-聚乙烯(非高度交联),小头和胶结植入物在翻修手术或Harris髋关节评分方面均非劣于或优于新材料植入体。金属-金属材质,骨水泥和表面重铸植入物翻修手术风险较高

近日,研究人员比较了不同种植体组合在初次全髋关节置换术(THR)后的效果差异。

本次研究为系统综述和荟萃研究,比较不同种植体组合的随机对照试验。种植体组合由轴承表面材料(聚乙烯、金属或陶瓷)、大小(36 mm以上或以下)以及固定技术定义,以金属-聚乙烯(非高度交联),小头和胶结植入物组合为参考。研究的主要终点为手术后0-2年以及2-10年翻修手术率,次要终点是Harris髋关节评分。

77个研究纳入系统综述,15项研究(3177个样本)纳入荟萃分析。研究认为其他的植入组合,相比于参考植入体在翻修手术率方面无显著优势。相比于参考植入体,金属-金属材料, 小头以及骨水泥植入(HR 4.4,95% CI 1.6 -16.6)或表面重铸(12.1,2.1-120.3)植物体术后0-2年和2-10年的翻修手术风险增加。31个研究(2888名患者)参与了Harris髋关节评分,没有其他的植入体组合得分超过参考植入物组合。

研究认为,对于初次全髋关节置换患者,传统的金属-聚乙烯(非高度交联),小头和胶结植入物在翻修手术或Harris髋关节评分方面均非劣于或优于新材料植入体。金属-金属材质,骨水泥和表面重铸植入物翻修手术风险较高。
