摘要
背景:随着计算机技术的进步,有限元分析法在脊柱侧凸生物力学研究中的应用逐渐增多。目的:回顾三维有限元分析法在脊柱侧凸生物力学研究中的应用与进展,总结其发展历程与特点,展望其发展前景与方向,以期为脊柱侧凸生物力学研究发挥指导作用。方法:由第一作者应用计算机检索PubMed数据库、Web of science数据库、万方数据库中1998至2019年出版的文献,英文检索词为"FEA,finite element analysis,3D FEA,scoliosis,adolescent idiopathic scoliosis,AIS";中文检索词为"有限元分析,三维有限元分析,脊柱侧凸,特发性脊柱侧凸,青少年特发性脊柱侧凸"。排除研究质量较差的文献及重复性研究,最终纳入48篇文献进行综述。结果与结论:(1)文献复习发现三维有限元分析在脊柱侧凸生物力学的研究中已有大量实践,取得了重要的进展;(2)在模拟外固定设备、优化手术方案、预估预后效果等方面应用较多,在病因学方面的研究较少;(3)三维有限元分析法的发展方向在于进一步提高模型的精细结构模拟,优化对非线性元件的生物力学特性的模拟,完善脊柱生长和代偿影响的模拟,以建立更能反映真实情况的三维有限元模型,提高有限元分析的可靠性。
BACKGROUND:Finite element analysis has been used commonly in the biomechanics research of scoliosis due to the process of computing technology.OBJECTIVE:To review the application and progress of three-dimensional finite element analysis applied in the study of biomechanics of scoliosis,and to summarize its development process and characteristics,and look forward to its development prospects and directions in order to play a guiding role in the biomechanical study of scoliosis.METHODS:The first author retrieved the PubMed,Web of Science,and Wanfang Database with the computer for studies published from 1998 to 2019.The key words were FEA,finite element analysis,3D FEA,scoliosis,adolescent idiopathic scoliosis,AIS.Studies with poor quality and repetitive studies were excluded,and 48 articles were finally included for review.RESULTS AND CONCLUSION:(1)Literature review found that three-dimensional finite element analysis has a lot of practice in the study of scoliosis biomechanics,and important progress has been made.(2)It has been widely used in simulating external fixator,optimizing surgical procedure and predicting prognosis,but less in etiology.(3)The development direction of three-dimensional finite element analysis is to further improve the fine structure simulation of the model,optimize the simulation of the biomechanical characteristics of non-linear elements,improve the simulation of spinal growth and compensatory effects,so as to establish a more realistic three-dimensional finite element model and improve the reliability of finite element analysis.
