Biomechanika – Osteosyntetické implantáty v traumatologii a ortopedii

Abstract

Dissertation thesis is dealing with osteosynthetic implants in traumatology and orthopaedics. The mechanical properties of materials used to manufacture implants are investigated. An analysis of the axial compression forces generating during the tightening of the headless Herbert screw in the 5th metatarsal is performed and a CAD model of the 5th metatarsal bone is created with the assignment of Young's modulus of elasticity to individual elements based on CT images in the Mimics software. Furthermore, a 3-point bending test of the new universal humeral nail is performed and the results are verified by a numerical simulation using the FEM method. Finally, a stress-strain analysis of the universal humeral nail under tensile loading is performed. Experimental, analytical, numerical and stochastic approaches in biomechanics are presented in the thesis.
