Abstract:
Objective: To construct a human cervical spine with bilateral vertebral artery fluid-solid coupling model .Methods: Helical CT images under the principle of reverse engineering and meshed in finite element model ( FEM ) related software were used to establish a human cervical spine with bilateral vertebral artery fluid-solid coupling model . In the process of modeling of vertebral body , vertebral artery , ligament , intervertebral disc , cartilage and endplate large anatomic data and cadaver experiments results were referenced .From the morphology and function the simulation of model with real physiological status was tested .Results: The study showed that the stress concentration on the surface of vertebral body and the blood wall of the bilateral vertebral artery , and the result of the volume flow rate-time curve of bilateral vertebral artery of the model were consistent with the published literatures .This model was well consistent with the clinical phenomenon .Conclusion: The three-dimensional FEM of the human cervical spine established by the introduced method has been effectively verified.The modeling method would provide a new tool for research on the cervical spine biomechanics .
