【摘要】：目的解剖观测趾足底固有动脉趾端动脉弓及其分支的解剖学特点。方法选取新鲜成人足标本8只,分别经足背动脉灌注红色乳胶,对第2趾趾足底固有动脉进行显微解剖,观察趾足底固有动脉弓的出现概率,位置及其口径,趾端动脉弓发出的弓上动脉的起始部位,走行方向,分支数目及血管口径情况。结果第2趾趾足底固有动脉趾端动脉弓恒定,动脉弓的外径为0.5~0.8 mm,平均外径为0.64 mm,动脉弓距趾端的距离为9.5~13.0 mm,平均为11.1 mm。动脉弓上发出5支恒定的分支,即趾端弓上动脉,我们将其命名为第1~5支趾端弓上动脉(由胫侧至腓侧)。结论第2趾趾端动脉弓及其发出的弓上动脉解剖恒定,可以采用弓上动脉为蒂的微型轴型皮瓣改善第2足趾再造后外形。
[Abstract]:Objective to observe the anatomical characteristics of the arch of the toe end of the toe plantar artery and its branches. Methods eight fresh adult foot specimens were perfused with red latex respectively through the dorsal artery of foot. The Arteria propria plantar of the second toe was dissected microscopically, and the probability, position and caliber of the arch of the plantar propria digitorum were observed, and the origin of the superior arch from the arch of the end of the toe was observed. Results the arterial arch at the end of the toe of the second toe plantar propria artery was constant, the external diameter of the arterial arch was 0.50.8mm, and the average diameter was 0.64 mm. The distance from the arcuate to the toe was 9.5 卤13.0 mm, with an average of 11.1 mm. There were five constant branches in the arterial arch, namely, the superior arch of the toe. We named it the 5th superior arch of toe (from tibial side to peroneal side). Conclusion the anatomic anatomy of the arch of the end of the second toe and the superior arch issued by it is constant. The microaxial flap pedicled with the superior arch artery can be used to improve the shape of the second toe after reconstruction.

【正文快照】： 为了使第2足趾移植再造拇指外形更接近正常手指,众多学者均对如何改善再造指外形进行了大量的研究[1~6]。对于指腹膨大及驼颈畸形(中节狭窄畸形),手术方式较多,其中指腹减凸联合中节增径术可一次手术改善两种畸形,是再造指整形的较好术式。其主要的整形理念也是在指腹膨大处设，
