Few reports describe the distribution of cutaneous perforators from the radial and ulnar arteries in the forearm. This study aimed to map the location of the cutaneous perforators that arise directly from the radial and ulnar arteries in cadavers.
Twenty-nine human cadaveric forearms were dissected. All radial and ulnar arteries cutaneous perforators were analyzed for total number and distribution. To define the distribution of each cutaneous perforator, the forearm was divided into 10 sections, with the sections labeled as 10%, 20%, 30%, and so on, beginning at the wrist.
From the radial artery, there were a total of 262 skin perforators with an average of 9.03 ± 2.28 (mean ± SD) per limb, whereas the total was 159 from the ulnar artery, with an average of 5.48 ± 1.49 per limb. Additionally, 128 (49%) radial artery cutaneous perforators and 75 (47%) from the ulnar artery were concentrated in the 0-30% section of the forearm. Both the radial and ulnar arteries had many cutaneous perforators in the forearm section labeled 70%, with 32 of 262 (12%) cutaneous perforators of the radial artery and 27 of 159 (17%) cutaneous perforators of the ulnar artery located here.
There were more cutaneous perforators from the radial artery than from the ulnar artery, and both were concentrated in the distal one-third of the forearm and in the forearm section labeled 70%. This information could be helpful when harvesting forearm flaps.
很少有报告描述前臂桡动脉和尺动脉皮穿支的分布情况。本研究旨在绘制尸体上直接发自桡动脉和尺动脉的皮穿支的位置。
解剖了29例人体尸体前臂。分析所有桡动脉和尺动脉皮穿支的总数及分布情况。为确定每个皮穿支的分布，将前臂分为10个部分，从腕部开始依次标记为10%、20%、30%等。
桡动脉共有262个皮穿支，每侧肢体平均为9.03±2.28个（均值±标准差），而尺动脉共有159个，每侧肢体平均为5.48±1.49个。此外，128个（49%）桡动脉皮穿支和75个（47%）尺动脉皮穿支集中在前臂的0 - 30%部分。桡动脉和尺动脉在前臂标记为70% 的部分都有许多皮穿支，桡动脉的262个皮穿支中有32个（12%）、尺动脉的159个皮穿支中有27个（17%）位于此处。
桡动脉的皮穿支比尺动脉多，且两者都集中在前臂远端三分之一以及标记为70% 的前臂部分。这些信息在切取前臂皮瓣时可能会有帮助。
