EFFECT OF MECHANICAL LOADING ON ELECTRICAL CONDUCTIVITY IN HUMAN INTERVERTEBRAL DISC Alicia R. Jackson, MS, Francesco Travascio, PhD, and Wei Yong Gu, PhD* Tissue Biomechanics Laboratory, Dept. of Biomedical Engineering University of Miami, Coral Gables, FL 33146
Abstract
NIH-PA Author Manuscript
Background—The intervertebral disc (IVD), characterized as a charged, hydrated soft tissue, is the largest avascular structure in the body. Mechanical loading to the disc results in electromechanical transduction phenomenon as well as altered transport properties. Electrical conductivity is a material property of tissue depending on ion concentrations and diffusivities, which are in turn functions of tissue composition and structure. The aim of this study was to investigate the effect of mechanical loading on electrical behavior in human IVD tissues. We hypothesized that electrical conductivity in human IVD is strain-dependent, due to change in tissue composition caused by compression, and inhomogeneous, due to tissue structure and composition. We also hypothesized that conductivity in human annulus fibrosus (AF) is anisotropic, due to the layered structure of the tissue. Method of Approach—Three lumbar IVDs were harvested from three human spines. From each disc, four AF specimens were prepared in each of three principal directions (axial, circumferential, and radial), and four axial nucleus pulposus (NP) specimens were prepared. Conductivity was determined using a four-wire sense-current method and custom-designed apparatus by measuring the resistance across the sample. Resistance measurements were taken at three levels of compression (0%, 10%, and 20%). Scanning electron microscopy (SEM) images of human AF tissue were obtained in order to correlate tissue structure with conductivity results.
