研究发现，致密骨的硬度与其孔隙率、补体、骨体积分数和表观密度高度非线性相关。弹性模数随孔隙率的增加而降低(0.55)，随骨组织体积的增加(10.92)和表观密度的增加(7.4)而增加。这些数据表明，致密骨组织的数量或密度的微小变化对其硬度的影响比松质骨中类似的变化更明显。
Stiffness of compact bone is found to be highly and nonlinearly dependent on its porosity, its complement, bone volume fraction and apparent density. Elastic modulus decreases as a power (0.55) of increasing porosity and increases both as a power of increasing bone tissue volume (10.92) and increasing apparent density (7.4). These data indicate that small changes in the amount or density of compact bone tissue exert a more pronounced influence on its stiffness than would similar changes in trabecular bone.
