摘要：

目的 通过微CT (micro CT)扫描重建获得手舟骨内血管高精度模型，为临床提供解剖学参考。  方法 选取3个新鲜上肢，从肱动脉插管并灌注铅丹造影剂，灌注结束24 h后解剖手舟骨。用micro CT扫描，构建手舟骨血管三维模型以观察手舟骨的骨内及骨外血管分布。  结果 手舟骨表面存在一个连续的“Ⅴ”型血管区，自掌侧桡腕关节远端的韧带附着区到达手舟骨腰部桡侧，进一步折返沿背侧嵴向近端尺侧延伸。手舟骨桡侧腰部的“Ⅴ”型折返点和背侧血管较为密集。手舟骨桡侧远端结节内的骨内血管较为丰富，有3～5支骨内主干血管，来自于桡侧腰部和结节周围的骨外血管。而手舟骨近端尺侧的骨内血管只有1～2支主干血管，且行程较长。舟月骨间韧带内的血管没有发出骨内分支。  结论 手舟骨表面存在一个连续的“Ⅴ”型的血管区。手舟骨桡侧腰部的“Ⅴ”型折返点和背侧血管较为密集，其骨内分支是手舟骨的主要供血来源。

Abstract:

 Objective The purpose of this study is to construct a high-resolution model focusing on the vascular pattern of the scaphoid by using micro CT and to provide anatomical reference for the daily clinical use.   Methods The lead-based contrast was perfused from the brachial artery and then the scaphoid bone was harvested. 3D models of the scaphoid bones were constructed by using micro CT to show how arteries distributed in and on the bones.   Results The arteries on the surface stretched from the distal radius covered with scaphoid fossa to the radial side of the waist and then head back to the distal ulna along the dorsoradial ridge, formed like a letter “Ⅴ”. The arteries gathered at the inflection point of the letter “Ⅴ” and the dorsal region. The tubercle region was anastomosed extensively with 3 to 5 major intraosseous vessels originated from the extraosseous vessels covering the waist and the tubercle. There are only 1 to 2 major intraosseous vessels entering the bone via a long route from the ulnar side. The vessels running in the scapholunate ligament didn’t spilt into any intraosseous branches.   Conclusion The superficial vascularity formes a “Ⅴ”-like pattern. The inflection point of the letter “Ⅴ” and the dorsal region display a dense vascularization and these vessels contributed a lot to the intraosseous vascularity.
