An ultrasonic technique was used to measure both the elastic modulus (Young's modulus) of trabecular bone material and the elastic modulus of the cancellous structure. The average trabecular modulus, measured on specimens obtained from three human and one bovine distal femora, was 13.0 GPa (S.D. 1.47) and 10.9 GPa (S.D. 1.57), respectively. On human specimens the structural elastic modulus was found to be related to the structural (apparent) density raised to the 1.88 power. The elastic modulus from the bovine specimens showed a more linear relationship with the density of the cancellous structure (density raised to the 1.57 power).
一种超声技术被用于测量松质骨材料的弹性模量（杨氏模量）以及松质结构的弹性模量。在从三个人类和一个牛的股骨远端获取的标本上测得的平均小梁模量分别为13.0吉帕斯卡（标准差1.47）和10.9吉帕斯卡（标准差1.57）。在人类标本上，发现结构弹性模量与结构（表观）密度的1.88次方相关。来自牛标本的弹性模量与松质结构的密度呈现出更线性的关系（密度的1.57次方）。
