本文用注射和透明法,观察了166例不同年龄(6(1/2)月胎儿～89岁)新鲜尸体手舟骨的动脉供应。手舟骨主要接受桡动脉及其掌浅支的血液供应。滋养动脉可分为背侧组和掌侧组。背侧组是舟骨的主要营养动脉,它供应该骨的近侧(70～80%),掌侧组仅供应该骨远侧(20～30%)。根据舟骨的血液供应特点,本文还对舟骨骨折后的缺血性坏死作了解释。
In this study, the arterial supply of fresh cadaveric hand bones from 166 different age (6 (1/2) months fetuses ~ 89 years old) was observed by injection and transparent method. Scaphoid mainly accept the radial artery and its superficial blood supply. Nourish the artery can be divided into dorsal and palmar groups. The dorsal group is the main nutrient artery of the scaphoid, which supplies the proximal (70-80%) of the bone and the palmar group supplies only the distal (20-30%) of the bone. According to the characteristics of the blood supply to the scaphoid, this article also explained the ischemic necrosis after scaphoid fractures.
