摘　　要：目的探讨胫后动脉穿支远端蒂复合组织瓣修复小腿远端创面的方法及疗效。方法 2014年9月—2017年8月,应用胫后动脉穿支远端蒂复合组织瓣修复12例小腿远端皮肤软组织缺损合并骨缺损。男8例,女4例;年龄25～66岁,平均41.3岁。致伤原因:交通事故伤7例,重物砸伤2例,胫骨骨髓炎并软组织溃疡、坏死2例,骨肿瘤切除术后骨和软组织缺损1例。8例一期修复,4例二期修复。皮瓣切取范围为6 cm×4 cm～10 cm×7 cm,肌瓣切取范围为4.0 cm×2.5 cm～8.0 cm×6.0 cm,骨瓣切取范围为4 cm×2 cm×2 cm～5 cm×4 cm×4 cm;供区胫骨骨缺损均采用自体髂骨植骨修复,创面直接拉拢缝合7例、部分缝合后游离植皮修复5例。结果术后12例胫后动脉穿支远端蒂复合组织瓣均成活,供、受区创面均Ⅰ期愈合。患者术后均获随访,随访时间6～12个月,平均10.8个月。复合组织瓣外观、颜色、质地及踝关节功能均满意。术后6个月X线片复查示骨瓣修复胫骨骨缺损处愈合良好,供区髂骨修复骨缺损处愈合良好。结论胫后动脉穿支远端蒂复合组织瓣血供丰富,是修复小腿远端局部软组织缺损合并局限性骨缺损创面的良好供区。Objective To investigate the clinical application and effectiveness of the composite tissue flaps pedicled with perforating branch of posterior tibial artery for repairing distal leg defects. Methods Between September 2014 and August 2017, 12 patients with skin and bone defects of distal leg were repaired with the composite tissue flaps pedicled with perforating branch of posterior tibial artery. There were 8 males and 4 females with an average age of 41.3 years(range, 25-66 years). The causes of injury included traffic accident injury in 7 cases, heavy crushing injury in 2 cases,tibial osteomyelitis with soft tissue ulcer and necrosis in 2 cases, and bone and soft tissue defect after resection of bone tumor in 1 case. Eight patients underwent primary repair, and 4 patients underwent second-stage repair. The size ranged from 6 cm×4 cm to 10 cm×7 cm in skin flap, from 4.0 cm×2.5 cm to 8.0 cm×6.0 cm in muscle flap, and from 4 cm×2 cm×2 cm to 5 cm×4 cm×4 cm in tibial bone flap. Tibial defects of the donor region were repaired by autologous iliac bone grafting, and the wounds were sutured directly in 7 cases and repaired by autologous skin grafting in 5 cases.Results All composite tissue flaps survived and both the recipient and the donor wounds healed primarily. All patients were followed up 6-12 months, with an average of 10.8 months. The appearance, color, texture of the composite tissue flaps and ankle function were satisfactory. X-ray films showed that the bone flap at the tibia defect and the ilium graft at the donor site both healed well at 6 months after operation. Conclusion The composite tissue flaps pedicled with perforating branch of posterior tibial artery has abundant blood, and it is a good donor region for repairing the distal leg defects combined with circumscribed bone defect.
