摘　　要：目的研究指背腱膜的血供特点和配布规律，为临床应用提供依据。方法用乳胶灌注３０只成人陈旧尸手，在４倍放大镜下观察１～５指指背腱膜的外在动脉；另取２只新鲜成人尸手，经甲醛碳素墨汁灌注后将标本制成厚、薄两种切片，在光镜及Ｌｕｚｅｘ－Ｆ型显微图像分析仪下测定其内在动脉的分支、数量和密度。结果共观察到外在动脉１１０６支，拇指２９７支，近端外径２．６４±０．２１ｍｍ（ｘ±ｓｘ，下同）；２～５指指背腱膜中均存在优势动脉。内在动脉走行于腱束结缔组织内，逐级分支并相互吻合，腱束内无血管。拇、示指指背腱膜内毛细血管数量和密度优于其它３指。结论指背腱膜损伤修复时，定要将腱旁组织与腱膜一起缝合有利于腱组织的愈合。Objective To study the blood supply and microvascular anatomy of extensor apparatus and provide evidence to clinical application. Methods Red latex was perfused into 30 adult cadaveric hands to observe under microscope the extrinsic arterial distribution in extensor apparatus. Carbonmethannal ink was injected into 2 fresh adult hands to study under microscope and with Luzex F micro image analyzer the branch,number and density of intrinsic arteries. Results 1 Conclusions In repair of extensor apparatus, the peritendinous tissue and extensor apparatus should be sutured together to assure healing of the tendon.
