单足供趾再造手技术的改进

目的 报道单足供趾再造手技术的改进及其临床应用结果。方法 对60只成人足标本进行解剖学研究。设计游Mu趾甲瓣及相邻的第2或第2和第3足趾的新方法，在临床上实施单足供趾再造拇指及其他两个手指。结果 解剖学研究证实，只要足背动脉存在，就能以第1跖背（底）动脉-第2跖背（底）动脉为蒂游离Mu趾皮肤趾甲瓣及相邻的第2或第2和第3足趾；分别用于再造拇指，食指和中指及拇指，中指和环指，均取得成功。结论 单足供趾再造手技术的改进能扩大手术适应证，并可提高再造手的功能。

Technical improvement of hand reconstruction by one foot donation

Objective To report the improvement of hand reconstruction with one foot donation technique and the results of its clinical application. Methods A new technique for harvesting the big toe skin nail flap and the adjacent second toe or the second and the third toes designed on the basis of anatomical study on the human foot and the clinical application for reconstruction the thumb and the other two fingers were perfomed. Results The anatomical study revealed that as long as the dorsalis pedis artery was intact, the big toe skin nail flap and the adjacent second toe or the second and the third toes could be harvested with the first dorsal(plantar) metatarsal artery the second dorsal(plantar) metatarsal artery as the arterial pedicle. The technique was successful to reconstruct the missing thumb, index and middle finger in one patient ,and the thumb, the middle and ring fingers for the other. Conclusion The technical improvement of hand reconstruction with one foot donation can enlarge its clinical indication and improve the function of the reconstruced hand.
