Development of the personalized finite element model of the adolescent idiopathic scoliosis and its significance / 生物医学工程学杂志

ABSTRACT

This study was aimed to develop the personalized finite element model (FEM) of spine of a scoliotic adolescent. We derived the data of spine of a scoliotic adolescent using spiral computed tomography. Then by using a series of computer aided design (CAD) software, the patient-specific 3D finite element model of spine of a scoliotic adolescent was developed. Results show the 3-D FEM of spine of AIS adolescent was established according to patient-specific geometric parameters. The model had an appearance similar an reality. We concluded that the way in this study is an exact and effective one to develop the FEM of spine of scoliotic adolescent. It is possible to analyze and research the biomechanical behavior of the scoliotic spine using the personalized FEM.
