The normal vascular anatomy of the articular disc of 48 antebrachiocarpal joints was studied in 24 dogs (12 puppies and 12 adult animals) using an India ink vascular injection technique. It was found that the articular disc receives its blood supply mainly from the palmar and dorsal branches of the palmar interosseous artery. Branches of these 2 arteries arborise and give direct peridiscal vessels to the dorsal, proximal and palmar sides of the articular disc. The peridiscal vessels ramify and anastomose with one another to form a cup-shaped terminal peridiscal capillary plexus around the disc which ends at the peripheral parts of the disc in a series of terminal capillary loops. This leaves the major central segment of the disc without blood vessels. The proportion of vascularised to nonvascularised areas of the disc depends upon the age of the animals. In young puppies, the degree of vascular penetration into the disc is quite extensive, while in adult animals it ranges from 15 to 25% of the discal width; the considerably larger central area of the articular disc is thus avascular.
采用印度墨水血管注射技术，对24只犬（12只幼犬和12只成年动物）的48个前臂腕关节关节盘的正常血管解剖结构进行了研究。结果发现，关节盘的血液供应主要来自掌骨间动脉的掌侧和背侧分支。这两条动脉的分支相互分支，并向关节盘的背侧、近端和掌侧发出直接的盘周血管。盘周血管相互分支并吻合，在关节盘周围形成杯状的终末盘周毛细血管丛，该丛在关节盘的周边部分以一系列终末毛细血管环结束。这使得关节盘的主要中央部分没有血管。关节盘血管化区域与非血管化区域的比例取决于动物的年龄。在幼犬中，血管穿透关节盘的程度相当广泛，而在成年动物中，血管化区域占关节盘宽度的15%至25%；因此，关节盘相当大的中央区域是无血管的。
