Vnitřní fixátory pro léčbu pacientů v traumatologii a ortopedii

Abstract

The dissertation thesis deals with the design and optimization of internal fixators using numerical calculations and experiments. In numerical calculations, implants are solved in direct interaction with bone tissue that is obtained from CT images. The material properties of bone tissue are described by non-homogeneous, in parts isotropic material, namely by assigning the modulus of elasticity to the individual elements. This results in a more precise distribution of the force acting on the individual parts of the implants. Bone tissue models are created according to the acquired CT images in software Materialise Mimics. Static and fatigue experiments investigate critical locations of fixators with respect to static and fatigue measurements. These results also serve to optimize implants. This improves their reliability and strength, contributing to faster and easier patient care.
