研究了椎骨和胫骨松质骨的抗压强度、断裂压缩、比例极限、比例极限压缩和弹性模量。标本取自年龄在14-89岁的男女尸体解剖受试者。随着年龄的增长，性别之间以及椎骨和胫骨之间的差异，大多数强度参数都出现了质的恶化。海绵状骨具有不寻常的机械性能，即使断裂，其抗压强度通常也会稳步增加;年轻男性的椎骨尤其如此。
A study was made of the compressive strength, compression at rupture, limit of proportionality, compression at the limit of proportionality and the modulus of elasticity of spongy bone from vertebrae and tibias. The specimens were obtained from autopsy subjects of both sexes aged 14-89 yr. There was a qualitative deterioration of most of the strength parameters with age and differences between the sexes and between vertebrae and tibia. Spongy bone had the unusual mechanical property that, despite rupture, its compressive strength often steadily increased; this was especially the case for vertebrae from young males.
