Lumbar facet joint injections are commonly employed in the treatment of low back pain and are considered to be relatively safe with few known complications. We report the case of septic facet arthritis following a periarticular facet injection in a patient with recurrent urinary tract infections. The literature is reviewed to identify epidemiological and clinical features of patients in whom septic facet arthritis developed after lumbar facet injection. The diagnosis of iatrogenic septic facet arthritis is often delayed because neurologic and constitutional signs and symptoms develop slowly. Serologic nonspecific markers of infection and appropriate imaging studies may be more sensitive for the early diagnosis of septic facet arthritis. Recalcitrant or worsening back pain after facet injections should prompt an investigation to rule out infectious causes.
腰椎小关节注射常用于治疗腰痛，且被认为相对安全，已知并发症较少。我们报告了一例复发性尿路感染患者在关节周围小关节注射后发生感染性小关节关节炎的病例。回顾文献以确定在腰椎小关节注射后发生感染性小关节关节炎的患者的流行病学和临床特征。医源性感染性小关节关节炎的诊断往往延迟，因为神经和全身症状及体征发展缓慢。感染的血清学非特异性标志物和适当的影像学检查可能对感染性小关节关节炎的早期诊断更敏感。小关节注射后顽固性或加重的背痛应促使进行调查以排除感染原因。
