Original abstract

This article is focused on computational modeling of an interaction of malleable lumbar spine fixation device with ambient bone tissue focusing on solving problems of clinical practise. It describes creation of computational model including model of geometry, materials, loads and constraints. There is a comparative stress strain analysis of spinal segment after fixation device application with its physiological state. Computations are performed with use of FEM method. To simulate natural way of loading we used the compression of motional spinal segment. Results show the difference between the system including intervertebral disc in between vertebras and the system with applied lumbar spinal fixation device.

Czech abstract

Tento článek je zaměřen na výpočetnové modelování interakce bederní páteře s poddajným fixátorem.Práce je zaměřena na řešení problémů klinické praxe. V práci je popsána tvorba výpočtového modelu, včetně modelu geometrie, materiálů, zatížení a vazeb. Provedena je srovnávací deformační a napěťová analýza páteře segmentu po aplikaci fixátoru s fyziologickým stavem. Řešení je provedeno pomocí metody konečných prvků. Simulovano je kompresní zatížení páteře. Výsledky ukazují podstatné rozdíly mezi fyziologickým stavem a stavem po fixaci.
