31 patients (29 with AIS and 2 with Scheuermann\'s kyphosis) developed late spinal infections. Mean age was 11.4 ± 2.3 years, 84% female, mean time from index surgery was 52.5 months. 25 had all stainless steel implants and 6 had cobalt chrome during the index procedure. Positive cultures were obtained in 5 patients (2 Staphylococcus Aureus, 1 Staphylococcus epidermidis, 1 Peptostreptococcus, 1 Pseudomonas aeruginosa) with cultures followed till 7 days post-operatively. At 2-years following the exchange, there was no change in coronal and sagittal alignment. Three (9%) patients developed subsequent infection necessitating implant removal.
A single-stage procedure consisting of implant removal, irrigation, and debridement, and replacement with all titanium implants is an effective treatment strategy in patients developing late wound infection following PSF with regards to maintenance of curve correction and minimizing recurrent infections.
31例患者(29例AIS和2例Scheuermann后凸畸形)发生晚期脊柱感染。平均年龄11.4±2.3岁,84%女性,从索引手术开始的平均时间为52.5个月.在索引过程中,25个具有全部不锈钢植入物,6个具有钴铬合金。5例患者获得阳性培养物(2例金黄色葡萄球菌,1表皮葡萄球菌,1肽链球菌,1铜绿假单胞菌)并进行培养,直到术后7天。在交换后的两年里,冠状和矢状排列没有变化。三名(9%)患者随后发生感染,需要移除植入物。
单阶段手术包括移除植入物,灌溉,清创,对于PSF后出现晚期伤口感染的患者,在维持曲线校正和最大程度地减少复发性感染方面,使用全钛植入物替换是一种有效的治疗策略。
