We investigated the intraosseous arteries of six normal cadaveric scaphoids using red lead injection and three-dimensional reconstruction with micro-computed tomography. The arterial entrances were generally located around the dorsal ridge, the insertion of the scaphocapitate ligament and the radial part of the radioscaphocapitate ligament. Two to three trunk arteries entered the scaphoid on dorsal ridge at the level of the waist. The distal part of the scaphoid was mainly supplied by arteries from the waist. The blood supply of about 40% of proximal part of the scaphoid was poor. The blood supply from the scaphoid dorsal ridge plays an important role, not only for the proximal part of the scaphoid, but also for the waist and even the distal pole. The intrascaphoid arterial pattern may be contributory to nonunion, especially in proximal pole fractures.
我们使用红色铅注入法和显微计算机断层扫描三维重建技术，对六具正常尸体舟骨的骨内动脉进行了研究。动脉入口通常位于背侧嵴、舟头韧带附着处以及桡舟头韧带的桡侧部分周围。两到三条主干动脉在腰部水平经背侧嵴进入舟骨。舟骨远端主要由来自腰部的动脉供血。舟骨近端约40%的血供较差。舟骨背侧嵴的血供不仅对舟骨近端，而且对腰部甚至远端都起着重要作用。舟骨内动脉模式可能与骨不连有关，尤其是在近端骨折时。
