Abstract
Specimens of femoral cortical bone from normal subjects and from patients with osteoporosis were mechanically tested in tension to destruction. The osteoporotic bone showed less strength and less stiffness than the normal bone; these reductions are related to the increased cavity area in osteoporosis. Further, the osteoporotic bone is not able to absorb as much energy before fracture as the normal bone; but this difference is not related to changes in cavity area.
摘要
对正常受试者和骨质疏松症患者的股骨干皮质骨标本进行拉伸力学测试直至破坏。骨质疏松症患者的骨骼比正常骨骼表现出更低的强度和刚度；这些降低与骨质疏松症中骨腔面积增加有关。此外，骨质疏松症患者的骨骼在骨折前无法像正常骨骼那样吸收那么多能量；但这种差异与骨腔面积的变化无关。
