In order to design a neurovascular flap from the dorso-ulnar aspect of the midhand for pedicled transfer to adjacent or distant locations, the surgical anatomy of the dorsal carpal branch of the ulnar artery (DCBUA) was studied in 12 cadavers. The DCBUA was identified in all specimens. It originates from the ulnar artery 1.6 to 4.4 centimeters proximal to the ulnar styloid, passing deep to the flexor carpi ulnaris tendon, and spirals superficially to the extensor retinaculum around the ulnar border of the wrist. Its terminal branches supply an undetermined area of skin overlying the ulnar metacarpals and the ulnar hypothenar region, either by direct cutaneous supply (3/12 specimens) or by septo-cutaneous perforators (8/12 specimens). The DCBUA is closely related to the dorsal sensory branch of the ulnar nerve, with which it supplies a common neurovascular territory.
为了设计一种从中手部背尺侧取材的带蒂神经血管皮瓣，以便转移至邻近或远处部位，我们在12具尸体上研究了尺动脉腕背支（DCBUA）的手术解剖结构。在所有标本中均识别出了DCBUA。它起源于尺动脉，位于尺骨茎突近端1.6至4.4厘米处，在尺侧腕屈肌腱深面穿行，并围绕腕部尺侧缘在伸肌支持带浅面呈螺旋状走行。其终末支通过直接皮支供血（3/12标本）或通过肌间隔皮穿支供血（8/12标本），为覆盖尺侧掌骨和尺侧小鱼际区域的未明确皮肤区域供血。DCBUA与尺神经背侧感觉支密切相关，二者共同供应一个神经血管区域。
