摘　　要：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.
