超声技术已被用于测量骨的弹性特性。8条人胫骨被用来确定和绘制皮质骨和松质骨的弹性特性。目前的研究表明，皮质骨至少在材料对称上是正交异性的。皮质骨的力学特性沿长度方向比沿圆周方向更均匀。皮质骨周围四象限的性质差异较小，小于10%，而松质骨周围的性质差异更为明显，约为皮质骨的5倍。松质骨的弹性特性沿长度和周长均表现出不均匀性和一定的一致性。
Ultrasonic techniques have been used to measure the elastic properties of bone. Eight human tibiae were used to determine and map the elastic properties of cortical and cancellous bone. The present study shows cortical bone to be at least orthotropic in its material symmetry. The mechanical properties of cortical bone are more homogeneous along the length than around the circumference. The variations in the properties around the quadrant of cortical bone are small, less than 10%, while differences in the properties around the circumference of cancellous bone are more apparent, approximately 5 times those of cortical bone. The elastic properties of cancellous bone exhibited inhomogeneity and some consistency pattern along both the length and the circumference.
