足内侧岛状皮瓣多向转位修复足部皮肤缺损

Repair of Skin Defect on Foot with Multiple Transference Medial Pedal Island Flap

作者对３０侧成尸和１５侧童尸的足内侧皮瓣进行了解剖观测。该皮瓣的供血动脉有内踝前动脉、跗内侧动脉、足底内侧动脉浅支和趾底内侧动脉浅支，外径分别为１．５±０．２ｍｍ、１．２±０．３ｍｍ、１．１±０．３ｍｍ和０．８±０．３ｍｍ。上述四条动脉在内侧楔骨处吻合形成展肌上缘动脉弓。每条动脉都有两条静脉伴行。在解剖研究的基础上我们施行了９例足内侧岛状皮瓣修复足跟、足背和足前部皮肤缺损，皮瓣全部成活。足内侧皮瓣切取之后。

The blood supply to the medial pedal flap had been observed on 30 adult and 15 child cadavers. The flap was supplied by the medial anterior malleolus artery,the medial tarsal artery,the superficial branch of the medial plantar artery and the superficial branch of the medial plantar hallucal artery. These four arteries were 1.5±0.2mm, 1.2±0.3mm, 1.1±0.3mm and 0.8±0.3mm each in outer diameter and anastomosed arch at the medial side of cuneiform bone to form an arterial arch(7-11cm long) at the superior border of the hallucal abductor. Each of the arteries runs alongside with two veins. Based on the anatomical observations, such flaps had been used clinically on 9 patients to repair their skin defects on heel, dorsum pedis and anterior portions of the feet. All the transferred flaps were alive. The walking ability were basically not affected.
