摘要/Abstract

摘要： 青少年特发性脊柱侧凸严重影响青少年的身心健康。过去，治疗性矫形器的研究忽略了肌肉因素的影响。针对这一问题，基于逆向工程原理，通过对脊柱CT数据模型进行三维重建，将脊柱周围的肌肉力导入脊柱肌肉力模型，并利用AnyBody软件进行仿真。从几何相似性和生物力学有效性两方面验证了所建立模型的有效性。为了获得所施加的矫形力与Cobb角和椎体位移之间的关系，建立了符合脊柱解剖结构的有限元模型，并对该有限元模型进行了脊柱侧凸的生物力学分析。合理控制椎旁肌对矫形治疗有积极作用，拟合方程可为医生施加矫形力提供参考。

Abstract: Adolescent idiopathic scoliosis seriously affects the physical and mental health of adolescents. In thepast, the research on therapeutic orthosis ignored the influence of muscle factors. Aimed at this problem, basedon the principle of reverse engineering, through the spine computed tomography data model of three-dimensionalreconstruction, muscle forces around the spine are imported into the spinal muscle force model and AnyBodysoftware is used for simulation. The geometric similarity and biomechanical effectiveness of the established modelare verified. In order to obtain the relationship among the applied orthopedic force, Cobb angle and vertebraldisplacement, a finite element model conforming to spinal anatomy is established, and then the biomechanicalanalysis of the finite element model of the scoliosis is carried out. Reasonable control of paravertebral muscles canplay a positive role in orthopedic treatment, and the fitting equation can provide a reference for doctors to applythe orthopedic force on patient.

Key words: adolescent idiopathic scoliosis, muscle force, computed tomography image, biomechanics
