腹部皮瓣修复多指全指皮肤脱套伤

Abdominal skin flaps for whole-finger degloving injury of multiple fingers

[目的]对腹部几种皮瓣修复多手指全指脱套伤的治疗进行总结。[方法]2000年以来对非拇指的多指全指脱套伤采用腹部皮瓣45例,其中腹部随意管状皮管修复10例,带蒂胸脐动脉穿支皮瓣15例,带蒂旋髂浅动脉皮瓣12例,腹部皮瓣包埋8例。Ⅱ期断蒂或腹部皮瓣切取,并进行分指或皮瓣成形手术。[结果]术后皮瓣均成活,3例3指分指术后出现远端皮肤坏死。随访时间5～36个月,患手平均掌指关节主动活动60°,指间关节30°。残存指神经的患指感觉恢复可达S3,其它手指精细感觉恢复差,均可持物。除3例3指远端皮肤坏死再次短缩致外形较差外,其余患手外观均满意。[结论]非拇指的多指全指脱套伤选择性的采用腹部皮瓣治疗,能够最大程度恢复外观及功能,仍是一种实用、安全且简便的手术方法。

[Objective]To evaluate several abdominal skin flaps used for treatment of whole-finger degloving injury of multiple fingers.[Method]Since 2000, 45 patients with whole-finger degloving injury of multiple fingers except the thumb were treated with transfer of abdominal skin flaps. Among these patients,10 were treated with random abdominal tubed pattern flaps,15 with pedicle skin flaps with thoraco-umbilical perforator artery,12 with pedicle skin flaps with superficial iliaccircumflex artery,and 8 with embedding with abdominal flaps.At the second-stage operation,fingers were dissected with pedicels or with abdominal flaps before fingerweb plasty and flap plasty were carried out for many times.[Result]All the skin flaps survived. Three fingers of 3 cases had distal cutaneous necrosis after finger web plasty.Follow-up from 5 to 36 months showed the active motion of metacarpophalangeal joints averaged 60°, and interphalangeal articulations averaged 30°.Sensation recovery reached S3 in fingers with remanent palmar digital nerve, but poor in other fingers. All fingers could perform grasping. The contour of fingers was fine except for the 3 cases of necrosis.[Conclusion]Treatment of whole-finger degloving injury of multiple fingers except the thumb with suitable abdominal flaps can restore the shape and function of hand to the greatest extent and is still a practical, safe and convenient operative method.
