通过动脉灌注研究了90侧不同年龄(婴儿至87岁)尸体跖骨的血液供应。分布于跖骨的动脉来自滋养动脉、骨膜动脉、骺-干骺动脉和假骺动脉。滋养动脉的近、远侧支供应皮质的内2/3～3/4;骨膜动脉发出少量小支进入骨皮质,供应皮质的外1/3～1/4;骺-干骺动脉呈轮辐状发自续于跖骨干的骨膜动脉浅丛,供应第1跖骨底和第2～5跖骨头;假骺动脉从骺-干骺动脉发出后,穿过非关节面区,供应第2～5跖骨底和第1跖骨头。跖骨滋养动脉的来源随跖骨而异。第1跖骨的滋养动脉通常来自足底深支和第1跖足底动脉,其他跖骨的滋养动脉主要来自跖足底动脉、足底弓及其穿支。本文对跖骨动脉分布的临床意义进行了讨论。
The blood supply to the metatarsal of 90 different age groups (infants up to age 87) was studied by arterial perfusion. Artery distributed in the metatarsal from the nourishing artery, periosteal artery, epiphyseal - epiphyseal artery and epiphyseal artery. Nourish the proximal and distal branches of the artery supply cortical 2/3 ~ 3/4; periosteal artery issued a small amount of small branches into the cortex, the supply of cortical 1/3 ~ 1/4; epiphyseal - epiphyseal artery spoke spoke The first metatarsal base and the 2nd to 5th metatarsal heads were obtained from the superficial periosteal artery following the metatarsal shaft. After the epiphyseal artery was sent out from the epiphysis-epiphyseal artery, Bottom and first metatarsal head. Metatarsal nourish the origin of the artery varies with metatarsal. The first metatarsal nodal artery usually comes from the plantar deep branch and the first plantar plantar artery, the other metatarsal nourish the artery mainly from the plantar plantar artery, plantar arch and its perforation. This article discusses the clinical significance of metatarsal artery distribution.
