Seven children (8 hips) with Choi's Type IV-B sequelae of septic arthritis of the hip underwent an unconventional reconstruction technique using a vascular-pedicled iliac crest graft to replace the destroyed femoral head and neck. The average age at surgery was 3.5 years, and the mean followup 7 years. Graft incorporation was observed in all patients; however, severe graft resorption was found in 1 hip, and mild resorption in 4 hips. The method of internal fixation of the iliac crest graft was not ideal and will require modification. Excellent femoral head-neck substitution with graft hypertrophy and remodeling was seen in 3 hips. In 7 hips (88%), vertical hip stability was achieved and a good range of hip motion was maintained. All children adapted very well to the operative procedures. At the final followup, the symptoms were those of limb-length discrepancy; pain was not a symptom.
7名患有髋关节化脓性关节炎Choi IV - B型后遗症的儿童（8个髋关节）接受了一种非常规重建技术，即使用带血管蒂的髂嵴移植来替代被破坏的股骨头和颈。手术时的平均年龄为3.5岁，平均随访7年。所有患者均观察到移植骨融合；然而，1个髋关节出现严重移植骨吸收，4个髋关节出现轻度吸收。髂嵴移植的内固定方法不理想，需要改进。3个髋关节出现移植骨肥大和重塑，股骨头 - 颈替代效果良好。7个髋关节（88%）实现了髋关节垂直稳定性，并维持了良好的髋关节活动范围。所有儿童对手术过程适应良好。在最后随访时，症状为肢体长度差异；疼痛不是症状。
