摘要
有限元分析方法是一种将复杂的大问题分解为多个小问题来解决的方法,借此它可以用多个小元素去模拟真实的物理系统,极大地推动了生物力学的发展。生物力学一直以来都是脊柱外科的热门研究方向,而有限元分析方法在脊柱生物力学中的应用也颇为广泛:可以在计算机上模拟健康的脊柱,研究正常脊柱在各种状态下的应力,为脊柱的基本应力研究提供帮助;可以模拟病变和退行性变时的脊柱,研究其在各种场景下的应力,为疾病的治疗提供方向;可以模拟不同的手术方式,研究不同的手术方式后脊柱以及内固定的应力情况,以此选出对患者来说最佳的手术方式;同时也可以模拟不同的内置物,研究不同内置物在体内和体外的应力,为术中内置物的选择以及内置物的升级优化提供指导。本文主要阐述有限元分析方法在脊柱外科中的应用及进展,为今后的脊柱生物力学研究和脊柱外科的临床治疗提供更多的参考。
Finite element method(FEM)is a method to decompose a large complex problem into several small problems to solve it.With this method,multiple small elements can be used to simulate the real physical system,which greatly promotes the development of biomechanics.Biomechanics has always been a hot research direction in spine surgery,and the finite element method is also widely used in spine biomechanics.It can simulate the healthy spine on the computer and study the stress of normal spine in various states,so as to provide help for the study of basic stress of spine.It can simulate the spinal column of pathological changes and degenerative changes,and study its stress in various scenarios,so as to provide direction for the treatment of diseases.Different surgical methods can be simulated to study the stress of the spine and internal fixation after different surgical methods,so as to select the best surgical method for patients;At the same time,it can also simulate different implants and study the stress of different implants in vivo and in vitro,so as to provide guidance for the selection of intraoperative implants and the upgrading and optimization of implants.This paper mainly discusses the application and progress of finite element method in spine surgery,and provides more references for the future study of spine biomechanics and clinical treatment of spine surgery.
