Application of Finite Element Analysis in Cervical Vertebrae Biomechanical Study

Finite element analysis is a matrix method for structure analysis,with the development of finite element technology and further understanding of mechanical characteristics of spine,it has become one of the important research methods used in spine biomechanics.Here is to introduce the concept and principle of finite element,the history in cervical vertebrae,and make a review on the biomechanical properties of cervical vertebra under pathologic,physiologic conditions,and injuries,the long term impact of different surgeries,and design and improvement assessment of internal fixation devices.With development of computer and finite element software,its application in cervical vertebrae will become increased and widespread.
