Explanted orthopedic implants from 54 patients with aseptic failure and 24 patients with prosthetic knee or hip infection were sonicated in polyethylene bags. The sensitivities of periprosthetic tissue and sonicate fluid cultures for the diagnosis of prosthetic joint infection were 54% and 75%, whereas the specificities were 98% and 87%, respectively. Sonication in bags improved bacterial recovery from the surface of orthopedic implants; however, it lacked specificity, due to bag leakage.
对54例无菌性失效患者和24例人工膝关节或髋关节感染患者取出的骨科植入物在聚乙烯袋中进行超声处理。假体周围组织和超声处理液培养对假体关节感染诊断的敏感性分别为54%和75%,而特异性分别为98%和87%。袋中超声处理提高了骨科植入物表面细菌的回收率;然而,由于袋子渗漏,其缺乏特异性。
