Hygroviscoelasticity of the Human Intervertebral Disc.

Abstract

In an effort to develop non-invasive diagnostic tools such as x-ray tomography the mechanical properties of human disc material were studied. Special attention was given to the anisotropic layer structure of the disc annulus in studying lamella behavior as well as multi-layer averaging relaxation properties. Viscoelastic response is significantly affected be water concentration in the material, a fact that is of utmost importance for control in laboratory testing. (Author)
