Abstract

Abstract:

BACKGROUND: Establishment of high-quality finite element model is an important basis of biomechanical analysis. The reports on three-dimensional finite element model of complete adolescent idiopathic scoliosis are less.
OBJECTIVE: To set up three-dimensional finite element model of PUMCIId1 adolescent idiopathic scoliosis for building ideal digitization platform for further biomechanical study.
METHODS: A 14-year-old female patient with PUMCIId1 adolescent idiopathic scoliosis was included as volunteer for the current study. CT images obtained from CT transverse scanning from T1 to sacrococcyx were imported into Mimics 16.0 software to form qualified three-dimensional geometric model, including thoracic cage, which was further delivered to Geomagic Studio 11.0 software to build three-dimensional finite element model by a series of modules and optimization of cleaning. The geometric model was imported to ANSYS 14.0 software to build complete three-dimensional finite element adolescent idiopathic scoliosis model by adding ligaments, setting unit type, and defining material properties.
RESULTS AND CONCLUSION: A complete three-dimensional finite element model of PUMCIId1 adolescent idiopathic scoliosis was built successfully, consisting of 522 887 tetrahedron elements and 730 rod elements, a total of 523 617 units and 159 008 nodes. Three-dimensional finite element model of PUMCIId1 adolescent idiopathic scoliosis was lifelike, and can be used as the reliable digital model for further biomechanical analysis.
