摘要
目的:通过标本解剖观测,为腕背支骨膜瓣的临床应用提供依据。方法:50侧成尸上肢标本,解剖观测骨间前动脉腕背支的走行、分支、分布及吻合情况。设计腕背支及其分支为蒂骨膜瓣移位术。结果:①骨间前动脉的腕背支距桡骨茎突上方6.0±1.0cm处,贴骨间膜背份下行分为内、外侧终支,分别与尺桡动脉腕背支相吻合。腕背支近端两侧分出尺、桡侧骨皮支,二者降支循尺、桡骨背份走行,并分出骨膜支分布;②临床应用15例,术后3～5个月骨折愈合,腕关节功能恢复。结论:以骨间前动脉腕背支为蒂的骨膜瓣可用于舟、月骨损伤修复。
Objective: To provid anatomical basis for clinical applications of the dorsal carpal branch of anterior interosseous artery. Methods: 50 sides of cadaveric upper extremities were deserved. The origin, course, branche distributions and anastomosis of the dorsal carpal branch of anterior interosseous artery were dissected. The operation method was designed for transposition of periosteal flap with dorsal carpal of anterior interosseous artery. Results: ①The dorsal carpal branch at the styloid process upper 6.0 ± 1. 0cm attaching dorsal of interosseous membrane of forearm sent off lateral and medial branch ends and anastomosed with dorsal carpal branch of ulner and radial artery. The perigee of dorsal carpal branch sent off bone skin branch at two sides. Both branches of descent went by dorsal of ulna and radius, sent off branch of periosteal distributions. ②15 cases were healed and the excellent function of the radiocarpal joints was restored in 3 - 5 months postoperatively.Conclusions: The periosteal flap with dorsal carpal branch of anterior interosseous artery can be used in repairing scaphiod and lunate bone.
