摘要
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。
The arterial supply of the human scaphoid was studied in 166 specimens of
hands from fresh cadavers of different ages ranging from 6(1/2)months of gestation
to 89 years old by injection and clearing techniques.The scaphoid receives its blood
supply mainly from the radial artery and its superficial palmar branch.There are
two groups of nutrient arteries,the dorsal and the volar nutrient arteries,entering
the scaphoid.The dorsal group of arteries which supplies the proximal 70% to 80%
of the scaphoid is the main contributor to the intraosseous blood supply.The volar
group of arteries only supplies the distal 20% to 30% of the bone.An explanation
for the cause of scaphoid necrosis following fracture on the basis of the vascularity
was proposed.
