BACKGROUND
The aim of this study was to assess the diagnostic performance of synovial aspiration in Girdlestone hips, without a Polymethylmethacrylate (PMMA) spacer, for the detection of infection persistence before total hip arthroplasty (THA) reimplantation.
METHODS
Seventy-four patients undergoing stage revision THA surgery were included in this retrospective cohort study. Both synovial cultures and serum C-reactive protein values were acquired before explantation of the THA and of the Girdlestone hip before reimplantation.
RESULTS
The diagnostic performance of the synovial aspiration of the Girdlestone hip achieved a sensitivity of only 13% and a specificity of 98%. The determination of the serum C-reactive protein value for Girdlestone hips achieved a sensitivity of 95% and a specificity of only 20%.
CONCLUSIONS
Our data show that the Girdlestone aspiration can neither reliably confirm nor exclude a persistence of infection.
背景
本研究的目的是评估在无聚甲基丙烯酸甲酯（PMMA）间隔物的Girdlestone髋关节中，滑膜抽吸术在全髋关节置换术（THA）再植入前检测感染持续存在的诊断性能。
方法
本回顾性队列研究纳入了74例行二期翻修THA手术的患者。在THA植入物取出前以及Girdlestone髋关节再植入前，均获取了滑膜培养物和血清C反应蛋白值。
结果
Girdlestone髋关节滑膜抽吸术的诊断性能仅达到13%的灵敏度和98%的特异度。Girdlestone髋关节血清C反应蛋白值的测定达到95%的灵敏度和仅20%的特异度。
结论
我们的数据表明，Girdlestone抽吸术既不能可靠地证实也不能排除感染的持续存在。
