Abstract

THE OBJECTIVE OF THIS STUDY IS TO MODEL COLLAGEN FIBERS REMODELING IN SOFT TISSUE OF THE HUMAN DISC, DUE TO MECHANICAL STIMULI. A 3-D NONLINEAR FINITE ELEMENT MODEL OF THE INTERVERTEBRAL DISC WAS CONSTRUCTED, INCLUDING ANNULUS, NUCLEUS AND SOME OF THE SPINAL STRUCTURES. THE ANNULUS CONSISTED OF COLLAGEN FIBERS, REPRESENTED BY CABLE ELEMENTS, EMBEDDED IN A FLEXIBLE GROUND SUBSTANCE. THE STRAIN ENERGY DENSITY CRITERION WAS EMPLOYED TO PREDICT REMODELING PROCESS IN THE COLLAGEN FIBERS. AFTER APPLYING PHYSIOLOGICAL LOADING CONDITIONS, DISTRIBUTION OF THE STRAIN ENERGY DENSITY WITHIN THE MODEL FIBERS WAS COMPUTED AND COMPARED WITH THE DISTRIBUTION OF COLLAGEN CONTENT IN THE NATURAL DISC STRUCTURE. THE RESULTS INDICATE THAT, LESS STIMULATED PARTS IN THE FE MODEL, HAVE LOW COLLAGEN CONTENT IN THE NATURAL DISC.
