Study on creating human tibia geometrical models

In order to create valid CAD (computer-aided design) model for planning orthopedic operations, rapid prototyping, designing of implants, etc., the accurate definition of geometry and topology of all regions of human tibia is essential. Therefore it is logical to base process of geometrical modeling of human tibia on its anatomical and morphological properties. This paper presents and compares the application of two modeling techniques for creating geometrical model of the human tibia. The techniques applied are developed considering the natural features of the human tibia bone, and not only standard CAD techniques for geometrical modeling which are common in standard engineering. The application of these methods can be extended to other bones in human body.
