This paper presents a systematic study in reviewing the application of finite element method for the analysis of correction mechanism of spine deformity due to scoliosis. The study is aimed at systematically (1) reviewing the use of finite element analysis in spine deformity case, (2) reviewing the modelling of pedicle screw and rod system in scoliosis surgery, and (3) analysing and discussing gap between the studies. Using the restricted key phrases, the review gathered studies from 2001 to 2021 from various electronic databases (Scopus, ScienceDirect, PubMed, Medline, and WorldCAT). Studies were included if they reported a finite element study on spine deformity. Studies that did not fully disclose their methodology and results had significant discrepancies, not published in English or not yet published were all disqualified. Regardless of inconsistencies in the methodological design of the studies, the quality of all papers was above the acceptable level. A total of fifteen manuscripts were considered for inclusion and were given a comprehensive review. This study indicates that analysing the forces acting on the spine, as well as the interrelationship between the force, stress, and degree of correction (which measured as the Cobb angle), could help to improve the corrective mechanism procedure of spine deformity. Pedicle screws and its placement strategies are also important as it influence the corrective forces for scoliosis treatment. Hence, the findings of this study could potentially be used as a guidance to develop a reliable finite element analysis that can predict the biomechanics responses during the corrective spine deformity treatment.
本文系统地研究了有限元法在脊柱畸形矫正机制分析中的应用。本研究旨在系统地（1）回顾有限元分析在脊柱畸形病例中的应用，（2）回顾脊柱侧凸手术中椎弓根螺钉和棒系统的建模，以及（3）分析和讨论研究之间的差距。本研究通过使用受限关键词，从 2001 年至 2021 年从各种电子数据库（Scopus、ScienceDirect、PubMed、Medline 和 WorldCAT）中收集了研究。如果研究报告了一项关于脊柱畸形的有限元研究，则将其纳入研究。如果研究没有充分披露其方法和结果，并且存在显著差异、未以英文发表或尚未发表，则将其排除在外。尽管研究的方法设计存在不一致，但所有论文的质量都高于可接受水平。共有十五篇论文被认为可以纳入，并进行了全面审查。本研究表明，分析作用在脊柱上的力，以及力、应力和矫正程度（以 Cobb 角测量）之间的相互关系，可以帮助改善脊柱畸形的矫正机制。椎弓根螺钉及其放置策略也很重要，因为它会影响脊柱侧凸治疗的矫正力。因此，本研究的结果可能被用作指导，以开发一种可靠的有限元分析，预测矫正脊柱畸形治疗过程中的生物力学反应。
