The architecture of vascular canals in cortical bovine bone was studied by a corrosion casting method. Prior to perfusion of the casting polymer, both cellular and nonmineralized components were removed to ensure proper impregnation into vascular canals--haversian and Volkmann's canals within secondary osteons and the vascular canals of periosteal circumferential lamellae. The resulting castings revealed an anastomotic system of canals within and between these two regions of cortical bone. The nature of these arborizations, their varying degrees of interconnectiveness, and their spatial, three-dimensional ordering are clearly demonstrated in this study.
采用腐蚀铸型法研究了牛皮质骨中血管管道的结构。在灌注铸型聚合物之前，去除细胞和非矿化成分，以确保聚合物能充分渗入血管管道——次级骨单位内的哈弗斯管和福尔克曼管以及骨膜环行板层的血管管道。所得铸型显示了皮质骨这两个区域内和之间的管道吻合系统。本研究清楚地展示了这些分支的性质、它们不同程度的相互连接性以及它们的空间三维排列。
