Abstract (EN): The main goal of the presented study is to understand the mechanical behaviour of a lumbar functional spine unit (FSU) L4-L5 with spondylolisthesis pathology. For the study of the healthy FSU the process includes the 3D reconstruction of the lumbar spine geometry from computer tomography (CT) images, finite element (FE) mesh definition and simulation of the spine mechanics under different load cases. The pathological model was built applying a posterior displacement of 6.81mm. The study of the two FE models, one healthy and the other with pathology, allowed identifying significant differences on the mechanical behaviour.
