The proximal row of carpal bones, including Os scaphoideum, Os lunatum and Os triquetrum, should be considered as a functional unit. The arterial supply stems from branches of the rete carpi dorsale et palmare, which pass through the Ligamentum radiocarpeum dorsale et palmare, respectively. In two-thirds of all cases, the scaphoid bone, the most frequently fractured of the wrist bones, is uniformly vascularized, so that by fracture both fragments retain their blood supply. In the remaining third of all cases, only one end of the scaphoid is supplied arterially. Thus the poorly vascularized fragment frequently becomes necrotic.
近排腕骨，包括舟骨、月骨和三角骨，应被视为一个功能单位。其血液供应源于腕背侧和掌侧网的分支，这些分支分别穿过腕背侧和掌侧桡腕韧带。在所有病例中，三分之二的情况下，腕骨中最常发生骨折的舟骨具有均匀的血管分布，因此骨折时两块碎片都能保留其血液供应。在其余三分之一的病例中，舟骨只有一端有动脉供血。因此，血管供应较差的碎片经常会发生坏死。
