Is the nucleus pulposus a solid or a fluid? Mechanical behaviors of the nucleus pulposus of the human intervertebral disc.
TL;DR: Whether the nucleus pulposus behaves more as a fluid or a solid in vivo depends on the rate of loading, and the authors' proposed stress‐strain law exhibited excellent agreement with the viscoelastic data.

Degeneration affects the anisotropic and nonlinear behaviors of human anulus fibrosus in compression

TL;DR: The results suggest that the highly organized and layered network of the anulus fibrosus, which gives rise to significant anisotropic effects in tension, does not play a major role in contributing to the magnitude of compressive stiffness or the mechanisms of fluid flow of theAnulus in the confined compression configuration.

Degeneration and Aging Affect the Tensile Behavior of Human Lumbar Anulus Fibrosus
TL;DR: Findings from the present study suggest that altered material properties of the anulus fibrosus affect the mechanics of the entire intervertebral disc.

Tensile properties of nondegenerate human lumbar anulus fibrosus
TL;DR: The results of the present study suggest that factors other than age, such as compositional and structural variations in the disc, are the most important determinants of tensile behavior of the anulus fibrosus.

Alterations in the mechanical behavior of the human lumbar nucleus pulposus with degeneration and aging
TL;DR: It was generally concluded that the nucleus pulposus undergoes a transition from “fluid‐like” behavior to more “solid‐like" behavior with aging and degeneration.
