背景：脊柱侧凸是一种包括椎体水平面旋转的复杂病理特点的三维脊柱畸形。有限元分析法可取代传统的生物力学实验法进行重复实验分析以及数字化仿真模拟，在脊柱侧凸的生物力学研究中的运用日益深入。 　　目的：旨在强调运用有限元分析法对脊柱侧凸的支具和手术治疗方面进行简要的阐述。 　　方法：以“脊柱侧凸；有限元”为检索词，检索PubMed数据库以及万方数据库1986年1月至2013年5月文献。选择文章主要内容与脊柱侧凸治疗的有限元分析直接相关的、代表性好、相关领域权威杂志的文章共38篇进行讨论。 　　结果与结论：如何设计出更加符合脊柱侧凸生物力学特征的个体化支具已成为研究热点。利用多重影像学技术将肋骨、胸骨以及骨盆等引入有限元模型中，分析研究脊柱侧凸施加三维矫形力的最佳方式。研究发现施加载荷最佳的方式是在脊柱侧凸的凸侧区域。有限元分析法可预测和评估患者的矫形过程及效果，进而制定出合理的矫形治疗方案。有限元分析法模拟分析内固定器械与脊柱之间的应力分布情况，更有效的预防治疗后并发症的发生。

BACKGROUND:Scoliosis is a complex spinal pathology characterized as a three-dimensional spine deformity combined with vertebral rotation. The finite element analysis can replace traditional biomechanical experiment for repeated experimental analysis and for processing digital simulation. It has been widely used in the study of scoliotic biomechanics. OBJECTIVE:To emphasize the application of finite element analysis on the brace and surgical treatment of scoliosis. METHODS:An online search of PubMed and Wanfang database was performed by using key words of“scoliosis, finite element”in Chinese for articles published between January 1986 and May 2013. A total of 38 papers related to finite element of scoliotic treatment, published in authorized journal and considered to be a representative, were selected. RESULTS AND CONCLUSION: How to design an individualized brace in accordance with biomechanical characteristics of scoliosis is the hot topic. By using multi-imaging technology, the rib, chest bone and pelvis are introduced into the finite element models, in a broader attempt to analyze the optimal three-dimensional orthopedic force pattern for scoliosis. The results of relative research showed that, the ideal loading pattern is given at the protruding area of scoliosis. Finite element analysis can predict and evaluate the orthopedic procedure and effect of patients, thus assisting the design of reasonable orthopedic treatment scheme. Through finite element analysis, we can simulate and analyze the stress distribution of internal fixator in spine, which contributes to prevent the complications.
