Biomechanical Analysis of Odontoid Fracture with Different Loads by Finite Element Method

Abstract

In this paper, a three-dimensional (3D) FE model of the healthy human axis was built considered cortical and cancellous bone. The model was validated using numerical results obtained by other authors. The stress distribution and potential fracture patterns of the anterior odontoid were analyzed under different loading direction within coronal plane and sagittal plane. The direction of loading is the main factor resulting in odontoid fracture. The results of FE analysis would be referenced by surgeon.
