We explored the cutaneous vascularity of the dorsal wrist area to examine the possibility of using reverse island flaps from this area for reconstruction of the hands and fingers. Four dominant arterial branches including the dorsal branches of the ulnar and radial arteries and terminal branches of the anterior and posterior interosseous arteries, which supplied the dorsal skin over the extensor retinaculum, were explored. The location, number, and diameter of skin perforators from these arteries were examined. The dorsal branches of the radial and ulnar arteries that passed along the dorsal cutaneous nerves gave off 2-4 skin perforators (diameter 0.1-0.2 mm) at the level of the carpal bone and always connected distally to perforating arteries from the palmar arterial system at the metacarpal head. Skin perforators from the anterior and posterior interosseous arteries were found passing through the extensor retinaculum in the second and third and fifth and sixth intercompartmental areas. The terminal branches of the anterior and posterior interosseous arteries always continued to the dorsal carpal arch, and lay over the distal carpal row. It may be anatomically possible to raise two different island flaps from the dorsum of the wrist.
我们研究了腕背区的皮肤血管分布，以探讨利用该区域的逆行岛状皮瓣修复手部和手指的可能性。我们探查了四条主要动脉分支，包括尺动脉和桡动脉的背支以及骨间前动脉和骨间后动脉的终末支，这些动脉为伸肌支持带上方的背部皮肤供血。我们检查了这些动脉发出的皮穿支的位置、数量和直径。沿背侧皮神经走行的桡动脉和尺动脉背支在腕骨水平发出2 - 4支皮穿支（直径0.1 - 0.2毫米），并在掌骨头处始终与来自掌侧动脉系统的穿动脉远端相连。发现骨间前动脉和骨间后动脉的皮穿支分别在第二和第三以及第五和第六骨间区穿过伸肌支持带。骨间前动脉和骨间后动脉的终末支总是延续至腕背侧动脉弓，并位于远侧腕骨列上方。从腕背部掀起两种不同的岛状皮瓣在解剖学上是可行的。
