在40侧成人足底标本、5侧足动脉透明标本和5侧足动脉铸型标本上,用肉眼和5倍放大镜下观察足底内侧神经分支(?)趾趾足底神经及动脉供应。(?)趾趾足底神经平均长14.9cm、横径1.7。神经血供主要来源于足底内侧动脉浅支和(?)趾胫侧趾底固有动脉。足底内侧动脉浅支外径为1.2mm。(?)趾胫侧趾底固有动脉外径1.3cm。(?)趾趾足底神经和供应动脉切取容易,该神经血管外径均能满足显微外科吻接要求,切取此神经血管后对足功能影响极小,是较理想的带血管蒂游离神经移植的供体。
The adult plantar specimens, the 5-sided arteries and the 5-sided arteries of the 40 cases were observed with the naked eye and 5x magnifier under the toes of the medial plantar nerve. (?) Toe toe soleus nerve average length 14.9cm, diameter 1.7. Nerve blood supply comes mainly from the superficial branches of the medial plantar artery and the tibial and posterior arteries of the toes. The superficial branch of medial plantar artery diameter 1.2mm. (?) Toe tibia and toe bottom of the natural artery 1.3cm in diameter. (?) Toe toe plantar nerve and the supply of easy to cut the artery, the diameter of the nerve vessels can meet the requirements of microsurgical kissing, cut the nerve blood vessels after foot function minimal impact is more ideal with vascular pedicle free nerve Transplant donor.
