A comparative scanning and transmission electron microscopy study was carried out on human compact lamellar bone. The results obtained fully confirm our previous findings which show that bony lamellae are not made up of parallel-arranged collagen fibers, as classically maintained. They are instead made up of highly interlaced fibers, and the lamellation appears to be due to the alternation of collagen-rich and collagen-poor layers, namely of dense and loose lamellae. In the light of these findings, lamellar bone must be considered a variety of woven- instead of parallel-fibered bone, as given in almost all the textbook of histology as an established datum. Such collagen organization of lamellar bone is briefly discussed in terms of bone biomechanics and osteogenesis.
对人类致密板层骨进行了比较扫描电子显微镜和透射电子显微镜研究。所获得的结果充分证实了我们先前的发现，即骨板并非如传统观点所认为的那样由平行排列的胶原纤维组成。相反，它们由高度交织的纤维组成，并且板层状结构似乎是由于富含胶原和缺乏胶原的层交替出现，即致密层和疏松层交替出现所致。鉴于这些发现，板层骨必须被视为一种编织骨而非平行纤维骨，而几乎所有组织学教科书都将平行纤维骨作为既定事实。本文从骨生物力学和骨生成的角度简要讨论了板层骨的这种胶原组织形式。
