当将已发表的与运动节段轴向压缩相关的桡侧椎间盘膨出数据与一个简单的力学模型进行比较时，可以得出椎体终板在压缩过程中应发生轴向向内膨出。在压缩状态下，圆盘中心的高度应保持恒定。用体视X线摄影测量方法测量了人腰椎标本的轴向终板膨出。轴向终板隆起的幅度显然与运动节段的线性压缩相当。因此，轴向终板膨出和下方骨小梁的变形是人体脊柱压缩特性的重要决定因素。
When the published data on the radial disc bulge in relation to the axial compression of the motion segment are compared to a simple mechanical model, it follows that an axial inward bulge of the vertebral endplates should occur during compression. The disc height at its center should remain practically constant under compression. The axial endplate bulge was measured in specimens of the human lumbar spine by stereoroentgen-photogrammetric methods. The axial end-plate bulge apparently is comparable in magnitude to the linear compression of the motion segment. Axial endplate bulge and deformation of the underlying trabecular bone are thus important determinants for the compression characteristics of the human spine.
