本文介绍了一个统计分析的汇总数据，从以前的一些实验有关的杨氏模量和松质骨组织的强度依赖于表观密度。结果表明，杨氏模量和强度都与组织表观密度的平方成正比，因此彼此成正比。结果表明，人体和牛组织的比例系数是不同的。可以得出结论，Wolff（Das Gesetz der Transformation der Knochen，Hirschwald，柏林，1892）的建议，即密质骨组织仅仅是更致密的松质骨组织，当仅考虑这两种组织的力学性能时，这不是一个准确的陈述。值得注意的是，人类松质骨的单个小梁的弹性模量的估计值从1到20 GPa变化，并建议这个问题需要进一步研究。
This paper presents a statistical analysis of the pooled data from a number of previous experiments concerning the dependence of the Young''s moduli and strength of cancellous bone tissue upon apparent density. The results show that both the Young''s moduli and the strength are proportional to the square of apparent density of the tissue and are therefore proportional to one another. It is shown that the coefficient of proportionality is different for human and bovine tissue. It is concluded that the suggestion of Wolff (Das Gesetz der Transformation der Knochen, Hirschwald, Berlin, 1892) that compact bone tissue is simply more dense cancellous bone tissue is not an accurate statement when only the mechanical properties of these two tissues are considered. It is noted that estimates for the elastic modulus of the individual trabecula of human cancellous bone vary from 1 to 20 GPa and it is suggested that this question needs further study.
