Treatment with a static or an articulating antibiotic-containing spacer is a common strategy for treating periprosthetic joint infection (PJI), yet many patients have persistent infections after spacer treatment. Although previous studies have compared the efficacy of a static and articulating spacer for treating PJI, few studies have assessed infection control from the time of spacer implantation, or they defined treatment failure as including reinfection, reoperation, or chronic suppressive therapy. Additionally, few studies have examined whether there is an interaction between spacer and pathogen type with respect to treatment success.

静态与铰接间隔器：传染性病原体类型是否会影响治疗成功？

使用静态或关节式含抗生素间隔器治疗是治疗假体周围感染 (PJI) 的常见策略，但许多患者在间隔器治疗后仍存在持续性感染。尽管之前的研究比较了静态和关节式间隔器治疗 PJI 的功效，但很少有研究评估间隔器植入后的感染控制，或者将治疗失败定义为包括再感染、再次手术或慢性抑制治疗。此外，很少有研究探讨间隔物和病原体类型之间是否存在与治疗成功相关的相互作用。
