Abstract:
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.
