穿过外展肌腱长肌腱的插入，并延伸至短肌腱短肌腱。然后将其放置在由拇指掌骨，radial骨外展肌和op骨肌形成的radial沟中。该动脉与拇指掌骨纵向中轴之间的距离在其底部为5mm，在<br>杆身为0.9至1.3mm，在其远端三分之一为10至15mm。

passing distal to the insertion of the abductor pollicis longus tendon and deep to the extensor pollicis brevis tendon. It then lay in the gutter formed by the radial aspect of the thumb metacarpal and the abductor and opponens pollicis muscles. The distance between this artery and the longitudinal central axis of the thumb metacarpal was 5mm at its base, 0.9 to 1.3mm at the<br>shaft and 10 to 15mm in its distal third.
