手背双逆行皮神经营养血管蒂皮瓣修复两手指背侧皮肤缺损

Retrograde neurocutaneous flap to repair dorsal skin defect of fingers

[目的]报道手背双逆行皮神经营养血管蒂皮瓣修复手指背侧皮肤缺损的方法。[方法]以桡、尺神经在手背侧的4个分支的营养血管为蒂设计各种皮瓣,同时应用其中的2种修复2个手指背侧的皮肤缺损。[结果]5例共10块皮瓣全部成活,伤指创面完全覆盖。[结论]逆行皮神经营养血管蒂皮瓣血供充分,不损伤知名血管,修复距离远,是修复手指背侧皮肤缺损的良好方法,可同时应用2个皮瓣以修复2个手指的皮肤缺损。

[ Objective ] To research the method to repair dorsal skin defect of fingers by using retrograde neurocutaneous flap. [ Method ] Adopting nutrient vessels of 4 nerve branches in hands of radial - ulnar nerve as pedicle, the flaps were designed and applied to repair dorsal skin defect of fingers. [ Result] All 10 flaps in 5 cases survived and wound area were covered. [ Conclusion] Retrograde neurocutaneous flaps have sufficient blood supply, with no injury to nominous vesels,and with long distance to repair. Therefore, it is an advantageous method to repair dorsal skin defect,futhermore, two flaps could be used to repair skin defect of two fingers at the same time.
