Surgeries' sterile conditions and perioperative antibiotic therapies decrease implant associated infections rates significantly. However, up to 10% of orthopedic devices still fail due to infections. An implant infection generates a high socio-economic burden. An early diagnosis of an infection would significantly improve patients' outcomes. There are numerous clinical tests to diagnose infections. The "Gold Standard" is a microbiological culture, which requires an invasive sampling and lasts up to several weeks. None of the existing tests in clinics alone is sufficient for a conclusive diagnosis of an infection. Meanwhile, there are functional imaging modalities, which hold the promise of a non-invasive, quick, and specific infection diagnostic. This review focuses on orthopedic implant-associated infections, their pathogenicity, diagnosis and functional imaging.
手术的无菌条件和围手术期抗生素治疗显著降低了植入物相关感染的发生率。然而,仍有高达 10%的骨科器械因感染而失效。植入物感染会带来巨大的社会经济负担。早期诊断感染将显著改善患者的预后。目前有许多临床检测方法可用于诊断感染。“金标准”是微生物培养,它需要进行有创采样,且耗时长达数周。目前,临床上没有任何一种单一的检测方法足以做出感染的明确诊断。同时,也有功能影像学方法,有望实现非侵入性、快速和特异性的感染诊断。本综述重点介绍了骨科植入物相关感染及其发病机制、诊断和功能影像学。
