Abstract
A non-linear sliding contact three-dimensional finite element model of a lumbar motion segment with disc implanted was developed to study the changes in load sharing and other biomechanical parameters. The load-displacement data from model predictions approximated one standard deviation of the experimental data. However, the model showed that the prosthesis altered biomechanics of the motion segment via both the rigid ball and cup design as well as the necessary dissection of the spinal elements for implantation. The incompressible design prevented loads from shifting to the facets in compression. The removal of the anterior annular restraint was responsible for an increase in motion as well as an increase in motion as well as an increase in the load transmitted across the facets in extension.
