目的：总结股前外侧皮瓣游离移植足踝部，尤其是小儿跟腱部皮肤软组织缺损的临床疗效。方法2010年2月～2014年12月，采用股前外侧皮瓣修复23例足踝部皮肤软组织缺损，男性17例，女性6例；年龄4～45岁，平均21岁。创面均伴血管、骨及肌腱外露，创面缺损范围4cm ×6cm～23cm ×18cm，皮瓣切取范围为6cm ×8cm～25cm ×20cm，供区游离植皮修复。结果1例移植皮瓣坏死，其余皮瓣及供区植皮均顺利成活，创面均Ⅰ期愈合。患者均获随访，随访时间8～46个月，平均16个月。皮瓣耐磨，无局部溃烂，均恢复保护性感觉。4例全足脱套伤患者皮瓣外形臃肿于术后8～12个月行二次手术皮瓣修整后，外形满意。结论股前外侧皮瓣具有切取范围大、血管口径粗、部位隐蔽等特点，由于股前外侧皮神经吻合可以获得较好的保护性感觉，可广泛用于足踝部皮肤软组织缺损的修复。“,”Objective To summarize the clinical efficacy of anterolateral thigh free flap to repair the soft tissue coverage of the ankle ,especially in children with soft tissue defects of Achilles tendon .Methods From Feb. 2010 to Dec.2014,23 cases with soft tissue defects of the ankle were repaired by use of the anterolateral thigh free flap.There were 17 males and 6 females aged from 4-45(average,21) years.Wounds involved exposures of vessels , bone and tendon.Wound defects ranged from 4cm ×6cm to 23cm ×18cm.Flap cutting ranged from 6cm ×8cm to 25 cm ×20cm.Donor sites were repaired by free skin grafting .Results One case developped flap necrosis; all other flaps and grafted skins were successfully survived ,and all wounds healed by the 1st intention.All patients were successfully followed up for 8 to 46 months,with an average of 16 months.No local ulceration occurred and all flaps have restored with protective sensation .Four cases with degloving injuries received cosmetic debulking opera-tion 8-12 months after initial surgery because of bloated appearance of the flap . Conclusion Anterolateral thigh free flaps have variety of advantages such as massive area ,thick vascular caliber,concealed area,etc..Therefore,the front lateral femoral cutaneous nerve anastomosis can provide a better protective sensation .It can be widely used in repairing skin and soft tissue defects in foot and ankle .
