To discuss the method to repair the defects of palm with the improved flaps pedicled with the dorsal carpal branch of ulnar artery.
The improved flaps were designed on the basis of anatomical distribution of the dorsal carpal branch of ulnar artery and the medial antebrechial cutaneous nerve, the ulnar artery was ligated and cut at the beginning of its dorsal carpal branch. The flap pedicled with dorsal carpal branch including the distal ulnar artery was achieved and applied clinically to repair 15 cases of the skin and soft tissue defects of palm from August 1997 to November 2001. The size of flaps ranged from 7 cm x 5 cm to 12 cm x 8 cm.
All of the cases were followed up 3 weeks to 6 months, and the flaps completely survived. There was no ischemia and necrosis at the distal part of flaps and the appearance and function was satisfactory.
The improved flap has long vascular pedicle, abundant blood supply and sensitive sensation, so it can be used to repair defect of palm.
探讨采用改良的尺动脉腕背支皮瓣修复手掌缺损的方法。
根据尺动脉腕背支及前臂内侧皮神经的解剖分布设计改良皮瓣，在尺动脉腕背支起始处结扎切断尺动脉，形成以腕背支包括尺动脉远心端为蒂的皮瓣，并于1997年8月至2001年11月临床应用修复15例手掌皮肤软组织缺损。皮瓣大小为7cm×5cm至12cm×8cm。
所有病例随访3周～6个月，皮瓣全部成活，皮瓣远端无缺血坏死，外观及功能满意。
改良皮瓣血管蒂长，血供丰富，感觉灵敏，可用于修复手掌缺损。
