足舟骨血供及其临床意义

Blood supply of the tarsal navicular bone and its clinical relevance

通过动脉灌注,对60侧不同年龄(新生儿至67岁)尸体足舟骨的血液供应进行了研究.舟骨的动脉分散发自足背动脉和足底内侧动脉的分支.舟骨辐射状动脉可分背侧和跖侧两组,背侧组供应舟骨背周区.跖侧组供应舟骨中央和跖侧区.对舟骨血管分布的临床意义进行了讨论.

The arterial supply of human tarsal navicular bone in 60 foot spe- cimens, ranging in age from the ne- wborn to 67 years old, was studied by means of arterial perfusion. The arteries of the navicular bone arise diffusely from the branches of the dorsalis pedis artery and the medial plantar artery. There are generally two groups of radiate arteries, the dorsal and the plantar. The former supplies the dorso-peripheral region of the bone, while the latter is dist- ributed to the central and plantar portion of the bone. This arterial distribution is discussed in terms of its clinical relevance.
