Macroescale Fracturation of Osseous Models

Abstract

Fracturing of osseous models is a field that allows to obtain advances in computer assisted medical simulations, as well as to prototype fragile objects as is the case with bones. This field of study includes the use of physical features of bones. Not all fracturing methods are valid with osseous models, due to the importance of considering the hierarchical structure of the bones. In this work, we focus on the study of bone fractures at the macroscale level and on obtaining fractures with a realistic appearance. Therefore, we have developed a tool that allows the fracture of osseous models, obtained through a 3D segmentation or scanning process, by using patterns represented with a 2D image. The different approaches for the fracturing of osseous models are also showed, and discussed the need to obtain more information about the fracturing process.
