ABSTRACT
This paper describes a study aimed at determining the load distribution produced by a healthy specimen upon weight bearing and comparing it to specimens with damage of different intervertebral disk quadrants. This allows establishing the degree at which the intervertebral disk contributes to load transmission and distribution. The study was conducted on a numerical-experimental basis in order to validate the results that stem from it. The experimental portion was performed with a reflective photo elasticity technique, while the numerical portion was performed with the ANSYS finite element package, Version 7.0.
