Abstract:

BACKGROUND: With the development of computer simulation technology, the researches on three-dimensional finite element of cervical traction combined with imaging technique become a focus, since it enables external experiments. 
OBJECTIVE: To summarize the literatures of cervical traction by the finite element analysis method.
METHODS: A computer-based online search of CNKI and PubMed databases was performed for articles related to the applications of finite element method in spinal mechanics and treatment of cervical spondylosis by traction.
RESULTS AND CONCLUSION: The finite element analysis method can probably replace the biological mechanical experiments to some degree, and the experimental conditions are controllable and the mechanics condition in vivo can be simulated without harm to the patients. Although the finite element analysis method is suitable to any complex construction theoretically, there remain difficulties and limitations in the spinal biology researches. Especially it exhibits some limitations in cervical vertebra due to small and complex structures. Therefore, related mechanical experiments and researches are required.
