摘要：

Multi-directional mechanical properties of human cancellous bone tissue were never measured using a compressive test with microscopic cubic specimens. In this study, a small scale compressive testing machine with nano meter resolution and a measurement system for Poisson's ratio with sub-nano meter resolution were developed to measure accurate microscopic mechanical properties of human CBT. The measured mean longitudinal (E-1), postero-anterior (E-2) and lateromedial (E-3) elastic moduli were 3.47 GPa (S.D. +/- 0.41), 2.57 GPa (S.D. +/- 0.28), and 2.54 GPa (S.D. +/- 0.22), respectively. ANOVA showed that the longitudinal elastic modulus (E-1) was significantly (p < 0.01) greater than the postero-anterior (E-2) and latero-medial (E-3) elastic moduli. For Poisson's ratios, v(12) was significantly (p < 0.01) higher than V-23 and V-31.
