摘　　要：目的 :为三角纤维软骨修复提供新的手术方法。方法 :在 40侧经动脉灌注红色乳胶的成人尸体标本上 ,解剖观测尺动脉腕背支的走行、分支及分布。结果 :尺动脉腕背支在豌豆骨近侧 3 .9cm处起于尺动脉 ,分为升支和降支。其中降支为腕背支的延续 ,大多数 ( 70 % )沿第 5掌骨尺侧缘径直下行达第 5掌骨头、体交界处与小指动脉尺侧支相吻合 ;少数 ( 3 0 % )降支至豌豆骨附近变为纤细 ,由小指动脉尺侧支上行与之吻合。降支或小指动脉尺侧支循第 5掌骨头尺侧走行时发 1～ 3支、外径 0 .3～ 0 .7mm骨膜支 ,分布于第 5掌骨背内面骨膜。结论 :可以尺动脉腕背支—降支为蒂设计第 5掌骨骨膜瓣转位修复三角纤维软骨的新术式。Objective: To provide a new therapeutic method for the transposition of triangular fibrocartilage complex( TFCC). Methods: Observing the course, branches and distribution of the dorsal carpal branch of ulnar artery by anatomising the adult cadaver specimens perfused with red latex at 40 sides artery. Results: Arising from the ulnar artery in the pisiform bone proximate 13.9 cm , the dorsal carpal branch of ulnar artery was divided into the ascending branch and the descending branch. Among them,The descending branch was the continue of the dorsal carpal branch of ulnar artery. Most of it (70%) went straightly down to reach the fifth metacarpal bone head along the fifth metacarpal bone path and anastomosed with the ulnaris branch of little finger artery on the boundary. The minority (30%) went down to near the pisiform bone and changed into slender, anastomosed with the ulnaris branch of little finger artery. When Going along with the fifth metacarpal bone head, the descending branch or little finger artery ulnaris sent off the 1～3 pieces periosteum branch with diameter 1.7±0.4 mm,which distributed in the periosteal on the back of fifth metacarpal bone.Conclusion: It is an easy practical method for repairing TFCC to achieve the transposition of fifth metacarpal bone periosteal flap pedicled with dorsal carpal branch of descending branch of ulnar artery.
