Abstract

Based on the data of atlantoaxial joint (AAJ) by contrast-enhanced CT scan, finite element modeling (FEM) of AAJ with vertebral artery (VA) was constituted and its feasibility and possible application were evaluated. CT data of AAJ with VA was selected from PACS in our hospital. The occipital, vertebral body and VA were distinguished and saved them as the STL format, the geometric and finite element model of AAJ with VA were established with adjusting the relevant parameters. Comparison was made between the model and 3D-image, and AAJ functions were simulated. FEM cannot clearly only show or measure the morphology of AAJ and VA, but observe the AAJ rotary motion and have a force analysis. In conclusion, FEM of AAJ with VA is a practical method on the CT data, and it has a high reliability, and can be used for studying the anatomy and biomechanics of AAJ.
