MODELING OF THE HUMAN CERVICAL SPINE USING FINITE ELEMENT TECHNIQUES

Efforts using finite element techniques to model the human cervical spine have illustrated viable techniques and approaches for simulating the three-dimensional (3D) motion of the human cervical spine. However, these studies also revealed difficulties because of insufficient geometric description for such a complex structure and the lack of experimental data for characterizing the mechanical behavior of the biological issues in this anatomical region. Recent advancement of computer technology has resulted in a large quantity of digital images of the human anatomical structure with high precision. In addition, new experimental techniques have also produced new test data on human biological tissue properties. This study developed a finite element representation of the human cervical spine using detailed 3D anatomical data. The model contains the important structural components of the cervical spine including the vertebrae, the disks, the ligaments, and the facets. Analytical/numerical schemes were developed to identify the viscoelastic material parameters from the quasistatic and dynamic test data of the soft tissues. Material models in the Dyna3D code were enhanced to simulate the mechanical behavior of these soft tissues. The motion segment models were then validated against the 3D global responses observed from the experiments.
