Abstract:
[Objective]To establish 3D finite element model of adolescent idiopathic scoliosis.Stress analysis on established 3D finite element model was done to compare the specific quantity of stress among every vertebra.[Method]Under the help of related softwares,3D finite element model was established from CT scan of a adolescent idiopathic scoliosi.A number of points were chosen on the model.Stress analysis was done in normal loading.[Result]Vertebral wedging and stress distribution showed significant regularity.The result was the largest in the apical region,and showed a gradual decrease to the end vertebral.[Conclusion]Relative biomechanical and clinical analysis can be easily conducted on 3D finite element model of scoliosis.It is possible to analyze diversity of stress on different conditions.
