Thirty-six patients were treated by Ilizarov transport in conjunction with muscle and myocutaneous flaps coverage. Thirty-one free flaps and 5 rotation flaps were performed. In 13 patients the procedures were carried out in 1-stage or simultaneous manner. In 23 patients, soft tissue coverage proceeded as the initial step followed by Ilizarov reconstruction as a delayed procedure. All flaps survived the simultaneous and delayed procedures and there were no anastomotic complications, but partial flap necrosis occurred in 1 patient 3 months after the index procedure at the time of flap elevation for docking site bone graft placement. The mean segmental defects were 10 cm and 5.8 cm for the simultaneous and delayed groups, respectively. The followup interval from the time of free flap coverage ranged from 2 to 44 months in the simultaneous group with a mean and median of 22 and 24 months, respectively. Twelve patients completed treatment in the simultaneous group with the followup interval from frame removal ranging from 3 to 36 months with a mean and median of 18 and 14 months, respectively. In the delayed group this interval ranged from 1 to 36 months, with a mean and median of 16 and 12 months, respectively, and a mean and median of 24.5 and 21 months, respectively, from the time of the index procedure. Union and absence of infection were achieved in 35 of 36 patients presenting with an acute open fracture, infected nonunion, or aseptic nonunion without stable soft tissue coverage. The Ilizarov fixators remained in place for a median of 9.5 months for the simultaneous group and 8.5 months for the delayed group. When soft tissue defects accompany an infected nonunion or high grade open fracture, the traditional Ilizarov treatment approach of soft tissue recruitment into the wound from the distant corticotomy site is inconsistent with the proven benefit of early soft tissue coverage. The combined approach provides a more reliable soft tissue bed for early cancellous bone grafting of the docking site and permits the accurate restoration of limb length for these very difficult problems.
36例患者接受了伊里扎洛夫骨搬运术联合肌肉和肌皮瓣覆盖治疗。共进行了31例游离皮瓣和5例旋转皮瓣手术。13例患者的手术为一期或同期进行。23例患者首先进行软组织覆盖,随后延迟进行伊里扎洛夫重建手术。所有皮瓣在同期和延迟手术中均存活,且无吻合口并发症,但1例患者在初次手术后3个月皮瓣掀起用于对接部位植骨时出现部分皮瓣坏死。同期组和延迟组的平均节段性骨缺损分别为10 cm和5.8 cm。同期组游离皮瓣覆盖后随访时间为2至44个月,平均和中位数分别为22个月和24个月。同期组12例患者完成治疗,去除外固定架后的随访时间为3至36个月,平均和中位数分别为18个月和14个月。延迟组该间隔时间为1至36个月,平均和中位数分别为16个月和12个月,从初次手术时间起平均和中位数分别为24.5个月和21个月。36例急性开放性骨折、感染性骨不连或无菌性骨不连且无稳定软组织覆盖的患者中,35例实现了骨愈合且无感染。伊里扎洛夫外固定架在同期组中位留置时间为9.5个月,在延迟组为8.5个月。当软组织缺损伴有感染性骨不连或高能量开放性骨折时,传统的伊里扎洛夫治疗方法,即将远处截骨部位的软组织引入伤口,与早期软组织覆盖已证实的益处不一致。联合治疗方法为对接部位早期的松质骨移植提供了更可靠的软组织床,并能准确恢复这些非常棘手问题的肢体长度。
