| 摘 要： | 目的 构建轻度青少年特发性脊柱侧凸患者的有限元模型，验证该模型的有效性，并进行有限元分析。 方法 建立1例轻度青少年特发性脊柱侧凸患者第6颈椎至第5腰椎的有限元模型，从几何形态及力学两方面对该模型进行有效性验证。分析该有限元模型在模拟前屈、后伸、左侧屈、右侧屈、左旋转、右旋转6种运动状态下，各椎体的应力变化。 结果 成功构建了轻度青少年特发性脊柱侧凸患者的有限元模型，模型总节点数为2561811个，总单元数为1547806个，并验证了该模型有效。模拟后伸、旋转活动时，畸形最明显处的椎体应力变化趋势与静态时相反。 结论 本实验所构建的轻度青少年特发性脊柱侧凸有限元模型有效，可进一步用于该疾病的相关研究。

| Abstract: | Objective To establish a finite element model of mild adolescent idiopathic scoliosis(AIS) patients, to verify the model, and to perform finite element analysis. Methods A finite element model of the mild AIS patient from the sixth cervical vertebrae to the fifth lumbar vertebrae was constructed. The model from two aspects of geometry and mechanics was verified. The stress changes of each vertebral body were simulated under movements of forward flexion, backward extension, left flexion, right flexion, left rotation and right rotation. Results A finite element model of the mild AIS patient has been established. The total number of nodes and total elements were 2561811 and 1547806, respectively. The validity of the model has been verified. The stress changes of the vertebral body in the most obvious deformity was opposite to that in the static state when simulating backward extension and rotation. Conclusions The finite element model of mild AIS is effective and can be further used for the research on the disease. |
