Modeling and Numerical Analysis of a Cervical Spine Unit

Chapter
Part of the Springer Series in Biomaterials Science and Engineering book series (SSBSE, volume 1)

Abstract

The main objective of this study was to obtain a sufficiently accurate model of a functional unit of human cervical spine, both implanted and non-implanted, and to analyze the biomechanical behavior of the implanted model, using Finite Element Method (FEM). Based on CT scans and 3D reconstruction techniques a multi-solid model that accurately reproduces the geometry of a cervical vertebra was developed. Using CAD techniques, a second model of functional unit of human cervical spine, both implanted and non-implanted, was developed. The developed model guarantees that the functional unit geometry can be imported and easily handled with ANSYS software, without compromising the functionality that this geometry accomplishes. The FEM was used to determine the stresses and strains acting at the bone–screws interfaces, during a flexion movement of the head.
