Objective: To establish 3D finite element model of the cervical vertebra. Methods:Volunteers’ cervical vertebras were observed by thin layer CT. Medical image processing software (Mimics 10.01), reverse engineering software (Geomagic Studio 10) and finite element software (MSC. Patran 2004) were applied to establish the finite element model. Results: 3D finite element model of the cervical vertebra was established, it comprised with 7 vertebral bones and 5 cervical intervertebral discs and related ligaments, including 44, 526 nodes and 248, 348 elements. Conclusion: 3D finite element model of the cervical vertebra was precise; it could be used to simulate biomechanical experiment.
