The pattern of the dorsal arterial supply of the thumb was studied by the dissection of 25 thumbs of fresh cadavers. A constant vascular axis was found, originating at the radial a. and communicating at the level of the middle third of the proximal phalanx with the arterial palmar circuit. The constant presence of this vascular axis and its connection with the palmar circuit permits the mobilisation of a dorsal metacarpal skin flap, with a distal pedicle and a reversed flow, that can be used for covering dorsal and palmar losses of substance in the thumb.
通过对25个新鲜尸体拇指的解剖,研究了拇指背侧动脉供应模式。发现了一条恒定的血管轴,起自桡动脉,在近节指骨中三分之一水平与掌侧动脉环相通。该血管轴的恒定存在及其与掌侧动脉环的连接,使得可以切取带远端蒂、血流逆向的手背皮瓣,用于覆盖拇指背侧和掌侧的组织缺损。
