Nineteen fresh, intact lumbar intervertebral joints (two vertebrae and the intervening joint) from twelve spines were loaded in a materials testing machine to determine their mechanical behavior. The loads applied were pure axial compression and complex loading conditions simulating physiological states. The measurements made included vertical load deflection, disc bulge, and strains in both the anterior and the lateral aspects of the vertebral body and in one lamina. The results showed that the posterior elements transmit considerable force during quasistatic complex loading, particularly in extension and frontal shear. When a healthy specimen is subjected to complex loading, "yielding or failure" occurs in the vertebral body and not in the annulus fibrosus of the disc.
从12个脊柱中获取了19个新鲜、完整的腰椎椎间关节（两个椎体及其间的关节），在材料试验机上加载以确定其力学行为。施加的载荷包括纯轴向压缩以及模拟生理状态的复合加载条件。测量内容包括垂直载荷挠度、椎间盘膨出以及椎体前侧和外侧以及一个椎板的应变。结果表明，在准静态复合加载过程中，后部结构传递相当大的力，尤其是在伸展和额状面剪切时。当健康标本承受复合加载时，“屈服或失效”发生在椎体而非椎间盘的纤维环。
