The dorsal arterial system of the thumbs' column is formed by two groups, one of which is lateral and the other medial to the tendon of the pollicis extensor longus. Both groups have several arteries, the territories of which are anastomosed. The proximal lateral arteries consist of the palmar thenar artery, the scaphothenar, the trapezothenar artery and the dorsal metacarpal artery. The proximal medial arteries consist of the branches of the radial artery or the collateral dorsal artery of the index. The distal lateral and medial arteries are branches of the proximal arteries or the palmar arteries of the thumb. Each artery can play a prominent role and can give a collateral artery to the thumb. An anastomosis between distal and proximal arteries is found in more than 40% of the cases and forms the long apparatus, described by the classics.
拇指柱背侧动脉系统由两组构成，其中一组位于拇长伸肌腱外侧，另一组位于其内侧。两组均有若干动脉，其供血区域相互吻合。近端外侧动脉包括掌侧大鱼际动脉、舟大际动脉、大多角大际动脉和掌背动脉。近端内侧动脉由桡动脉分支或示指背侧副动脉组成。远端外侧和内侧动脉是近端动脉或拇指掌侧动脉的分支。每条动脉都可发挥重要作用，并可向拇指发出一条侧支动脉。在超过40%的病例中可发现远端和近端动脉之间的吻合，形成了经典文献中描述的长装置。
