The extraosseous and intraosseous vascularity of the carpal scaphoid was studied in 15 fresh cadaver specimens by injection and clearing techniques. The major blood supply to the scaphoid is via the radial artery. Seventy to eight percent of the intraosseous vascularity and the entire proximal pole is from branches of the radial artery entering through the dorsal ridge. Twenty to thirty percent of the bone, in the region of the distal tuberosity, receives its blood supply from volar radial artery branches. There is an excellent collateral circulation to the scaphoid by way of the dorsal and volar branches of the anterior interosseous artery. An explanation for the cause of scaphoid necrosis on the basis of the vascular anatomy is proposed. The volar operative approach would be least traumatic to the proximal pole's blood supply.
通过注射和清除技术，在15个新鲜尸体标本上研究了腕舟骨的骨外和骨内血管。舟骨的主要血液供应来自桡动脉。骨内血管的70%至80%以及整个近端极来自通过背侧嵴进入的桡动脉分支。远端结节区域20%至30%的骨接受来自桡动脉掌侧分支的血液供应。通过骨间前动脉的背侧和掌侧分支，舟骨有良好的侧支循环。基于血管解剖学对舟骨坏死的原因提出了解释。掌侧手术入路对近端极血液供应的创伤最小。
