Virtual and Experimental Studies about Human Walking - Virtual Lower Leg Environment - Innovative Design of Tibia Nail

Abstract:

To re-create a 3D parametrical environment it was used a CAD software which permits to define complex models. First, there were defined the main bone components as femur, tibia and pelvis by using the CT images. The contours of the CT images were transferred to CAD environment where, step by step, and section by section, the virtual bones were defined. The model of the pelvis and of the lower limbs during a virtual walking was recomposed by using kinematic parameters determined by filming the human subject. In this case the entire behavior of each bone component was determined, including that of the tibia. The variations of force and torque which auctioned over the tibia were determined and applied to the fractured tibia with the new models of nails.
