Abstract

Adolescent idiopathic scoliosis (AIS) is a musculoskeletal disorder characterized as three-dimensional (3D) deformity, and bracing is a common conservative treatment for AIS. Finite element analysis (FEA) is a technique for numerically solving the differential equations arising in engineering and mathematical modeling and has been widely used in biomechanical studies. Recently, FEA has been under intensive focus to improve the clinical outcomes of brace treatment. This review focuses on using FEA to assist brace treatment for AIS and technique choices that may be encountered during the construction of the finite element model (FEM). The construction of geometric models, the mechanical property, element type, the boundary condition, and the observation items of FEA have been summarized while establishing FEM. In each technical aspect, different fields and limitations of FEA are discussed. The observation items based on FEA are collected in addition to the biomechanical value in clinical research. We also summarized the technical aspects of brace treatment by FEA and observation items and provided guidance and directions to improve the brace treatment.

支架治疗青少年特发性脊柱侧凸的有限元分析。

青少年特发性脊柱侧凸(AIS)是一种以三维(3D)畸形为特征的肌肉骨骼疾病，支具是AIS常见的保守治疗方法。有限元分析(FEA)是一种数值求解工程和数学建模中出现的微分方程的技术，已广泛应用于生物力学研究。近年来，有限元分析已成为提高支具治疗临床效果的热点。本文综述了有限元分析在辅助AIS支架治疗中的应用，以及在有限元模型构建过程中可能遇到的技术选择。在建立有限元法时，总结了几何模型的建立、力学性能、单元类型、边界条件和有限元分析的观测项目。在每个技术方面，讨论了有限元分析的不同领域和局限性。除了临床研究中的生物力学价值外，还收集了基于有限元分析的观察项目。并通过有限元分析和观察项目总结了支具处理的技术方面，为改进支具处理提供了指导和方向。
