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.
