We have analysed the development of the cartilage canals in the tarsal navicular in 26 human foetuses and infants, aged between 12 weeks after gestation and 10 months, using a technique of transparentation and serial histological sections of the bone. The formation of cartilage canals starts in the first 12 to 13 weeks of gestation and can be seen by transparentation at 17 weeks after gestation. They increase in number with the age of the foetus or infant and develop a branching pattern almost to the centre of the tarsal navicular. They begin and are more numerous on the dorsal surface of the cartilage structure.
我们使用骨骼透明化和连续组织切片技术,分析了26例妊娠12周后至10个月大的人类胎儿和婴儿跗舟骨中软骨管的发育情况。软骨管的形成始于妊娠的前12至13周,在妊娠17周时可通过透明化观察到。它们的数量随着胎儿或婴儿的年龄增加,并发展出一种几乎延伸至跗舟骨中心的分支模式。它们起始于软骨结构的背侧表面,且数量较多。
