Abstract

Values for the compressive breaking load of lumbar vertebrae at physiological strain rates show enormous scatter across the population, ranging from 0.8 kN to nearly 16 kN. Increase in strength was found at faster strain rates, but differences in compressive strength between upper and lower lumbar vertebrae were not significant. Hydraulic strengthening does not appear to contribute to the compressive strength at the strain rates studied.

摘要

腰椎在生理应变率下的压缩破坏载荷值在人群中呈现出极大的离散性,范围从0.8千牛到近16千牛。在更快的应变率下发现强度有所增加,但上腰椎和下腰椎之间的抗压强度差异并不显著。在所研究的应变率下,液压强化似乎并未对抗压强度产生影响。
