有限元方法在上颈椎生物力学研究中的应用进展

生物力学因素在上颈椎疾患的发病机制中具有十分重要的意义。传统的生物力学实验方法,如动物实验、物理实验、体外(尸体)实验存在不足。有限元方法作为一种新的生物力学研究方法,可在持续性研究中重复及改变任何质量与定量变化,同时可提供局部以及内部的机制反应,有效地弥补现行方法的不足。本文就其在上颈椎生物力学研究中的应用进行综述,包括各种上颈椎有限元模型的建模方法,及其对上颈椎病理生理机制和内固定器械的生物力学分析。

Biomechanical application of finite element method in upper cervical spine

Biomechanics plays an important role in the pathogenesis of upper cervical spine disease. Traditional biomechanical test,such as animal experiment,physical experiment and vitro experiment exists many problems. Finite element method,a new biomechanical method,can repeat in sustainability study,change quality and quantity,provide the manifestation of local and internal region and make up the deficiency of current methods. The paper summaries the biomechanical application of finite element method in upper cervical spine,including the finite element modeling,pathophysiological mechanism of upper cervical spine and biomechanical analysis of internal fixation devices.
