Abstract

Abstract:

BACKGROUND: The original data of the medical biomechanics finite element analysis often come from body CT images. Wide range CT scanning can cause damage to human.
OBJECTIVE: To establish a three-dimensional finite element model of rabbit tibial fracture.
METHODS: A 1-year-old male New Zealand white rabbit was selected, sawing the middle of the left tibia by surgery. Reading the 135-layer of 0.625 mm thick consecutive CT DICOM3.0 format images of rabbit left tibial with the MIMICS10.01 software directly. The surface mesh model was established by images positioning, images organizing, interpolated processing and surface smoothing processing, then the meshmodel was introduced into ANSYS10.0 software directly to mesh body, and then transferred the body mesh to MIMICS10.01 for assignment on the basis of CT values.
RESULTS AND CONCLUSION: A realistic appearance and calculation accuracy three-dimensional finite element model of rabbit tibial fracture was established. The model was real and effective by applying load and analyzing. The result showed the three-dimensional finite element model of rabbit tibial fracture could be made faster and more accurate by applying MIMICS10.01 software and ANSYS10.0 software. The establishment of the model lays a foundation for rabbit further biomechanical analysis of fracture healing.
