NEJM:髋关节囊内骨折的骨水泥或非骨水泥半髋关节置换术比较

2022-02-11 MedSci原创 MedSci原创

在60岁或以上的髋关节囊内骨折患者中,与非骨水泥型髋关节置换术相比,骨水泥型半髋关节置换术的生活质量稍高,但假体周围骨折的风险较低。

关于髋部骨折患者在半关节置换术中使用骨水泥治疗目前仍存在争议。与现代非骨水泥半关节置换术相比,骨水泥半关节置换术后生活质量的数据十分有限。

近日,顶级医学期刊NEJM上发表了一篇研究文章,研究人员进行了一项多中心、随机、对照试验,比较了60岁或以上的髋关节囊内骨折患者采用骨水泥与非骨水泥半髋关节置换术的疗效。该研究的主要结局是在随机化后4个月使用EuroQo组5维(EQ-5D)问卷上的效用评分测量与健康相关的生活质量(评分范围为-0.594至1,分数越高表示生活质量越好;最小临床重要差异的范围为0.050到0.075)。

该研究共有610名患者被分配接受骨水泥半髋关节置换术,615名患者接受现代非骨水泥半髋关节置换术;71.6%的患者在4个月时可获得随访数据。骨水泥组患者的平均EQ-5D效用评分为0.371,非骨水泥组患者的平均EQ-5D效用评分为0.315(调整后的差异为0.055;95%置信区间[CI]为0.009至0.101;P=0.02)。1个月的组间差异与4个月相似,但12个月的差异小于4个月的差异。

骨水泥组和非骨水泥组12个月时的死亡率分别为23.9%和27.8%(死亡比值比为0.80;95%CI为0.62至1.05)。各组中分别有0.5%和2.1%的患者发生假体周围骨折(比值比[非骨水泥与骨水泥]为4.37;95%CI为1.19至24.00)。两组其他并发症的发生率相似。

由此可见,在60岁或以上的髋关节囊内骨折患者中,与非骨水泥型髋关节置换术相比,骨水泥型半髋关节置换术的生活质量稍高,但假体周围骨折的风险较低。

J Arthroplasty:两种股骨假体远端设计及应用特点

  摘要:本研究旨在比较近端涂层股骨假体远端的不同设计对假体周围骨改建的影响。本前瞻性研究共包括21例一期同时接受双侧全髋关节置换的病例,其每一侧髋关节均随机使用近端设计完全相同而远端分别为锥形或圆柱形结构的假体中的一种。在术后平均7年时的最后一次随访时,所有髋关节的临床和影像学结果均良好。松质骨硬化现象在柱形柄周围发生于Gruen2区和6区;而在锥形柄周围则发生在2/3区之间以及6/5区之间。锥
