| Abstract: | Objective To establish a 3-dimensional finite element model of cervical spine. Methods The co-ordinate data of the vertebras were obtained from CT scan images of a healthy male adult volunteer＇ s cervical spine and converted into point cloud data by Mimics software. Geomagic studio was used to establish the geometry model of the C2 - C7 cervical spine. The geometry model was meshed and the finite element model was established by ANSYS software. The model was validated by comparing the intersegmental ranges of motion with document. Results A finite element model of cervical spine with intimate anatomy was established and validated. Conclusion The model has good biofidelity and can be used to study the post- laminectomy change of intersegmental ranges of motion. |
