Complications related to femoral spacers are common during addressing infected total hip arthroplasties by 2-stage revision. We evaluated 11 patients who had 2-stage revisions with massive bone loss after removal of the infected components by a trochanteric osteotomy. All femoral cement spacers were assembled on intramedullary nails. Femurs were protected by a plate, whereas acetabuli were augmented by a cage or roof ring depending on the remaining bone stock. This additional hardware was covered with antibiotic-impregnated cement. Infection was eradicated in 10 (90.9%) of 11 patients within 3.5 months in average. None of the patients had spacer fracture, periprosthetic fracture, or dislocation. Augmentation by hardware covered with antibiotic-impregnated cement is effective and may reduce complications until definitive treatment is performed.
在通过两阶段翻修术解决感染性全髋关节置换术后，与股骨间隔器相关的并发症很常见。我们评估了 11 例患者，他们在通过转子间截骨术去除感染性成分后，发生了大量骨丢失，进行了两阶段翻修术。所有股骨水泥间隔器都装在髓内钉上。股骨用钢板保护，髋臼根据剩余骨量用笼或顶环增强。额外的硬件用抗生素浸渍的水泥覆盖。11 例患者中有 10 例（90.9%）在平均 3.5 个月内消除了感染。没有患者出现间隔器骨折、假体周围骨折或脱位。用抗生素浸渍水泥覆盖的硬件增强是有效的，可以减少并发症，直到进行确定性治疗。
