[Research on biomechanics properties of occipito-atlantoaxial complex by finite element method].

Based on the research history of the biomechanics of occipito-atlantoaxial complex, we have systematically summarized the use of finite element method for studying biomechanics of occipito-atlantoaxial complex. Then, combined with four basic principles of establishing an effective finite element model for mechanics, our comments are focused on the establishment of geometrical model, finite element model, finite element mechanics model, and on the method and implementation for validating the model. In addition, the developing trends, existing problems and future researching directions in this area are discussed.
