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 T 1 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 ANDCONCLUSION:
A complete three-dimensional finite element model of PUMCIId1 adolescent idiopathic scoliosis was built successful y, 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.
