目的：为拇指再造提供解剖学依据。方法：用３０例（男１９，女１１）成人趾作组织切片，取近、远侧横纹及二者中点处的横断层切片，对趾跖固有动脉和神经的位置、管径进行观测。结果：趾跖腓侧固有动脉和神经，Ｉ断层腓侧动脉 ３、４区出现率为 ９２．３１±４．９５％，Ⅱ、Ⅲ断层位于 ４、５区内者占 ８６．５４±6．３４％。Ⅰ、Ⅱ、Ⅲ断层腓侧神经 ４、５区出现率为 ９７．４５±２． ８８％，它们纵径平均值分别大于 １．０８ ｍｍ和 １． ６３ ｍｍ。趾跖胫侧固有动脉和神经在 ８、９区内者均高于 ９２％以上，其纵径平均值分别大于 ０． ６８ ｍｍ和 １． ６７ ｍｍ。结论：排侧动脉截面积均大于胫侧，腓侧可被视为优势动脉。神经与同名动脉基本位于同一区内。
Objective: To provide anatomical basis for thumb reconstruction. Methods: Totally 30 adult male and female toes were used to make tissue sections, and the transverse and transverse stripes at the middle and midpoint of the transverse section were taken. The position and diameter of the native arteries and nerves in the plantar metatarsals Observation. Results: The occurrence rate of the arteries and nerves of the toes in the fibular side was 92.31 ± 4.95% in the 3,4 zone of the fibular artery of the I-cut, and 86.54 ± 6 in the zones 4 and 5 of the II and III lesions. 34%. The incidences of peroneal nerve in zone I, II and III were 97.45 ± 2. 88%, their mean longitudinal diameter is greater than 1.08 mm and 1 respectively. 63 mm. The tibial plantar tibial artery and nerve in the 8,9 area were higher than 92%, average longitudinal length were greater than 0. 68 mm and 1. 67 mm. Conclusion: The lateral artery cross-sectional area is larger than the tibia, and the fibular side can be regarded as the dominant artery. Nerves and the same name of the artery in the same area.
