Examination of stability of osteo-syntetic matherial by software bone stimulator
Abstract
Introduction. Softwaresimulator model (SSM) is a computer program written in one of the many programming languages. Based on the given input data on mathematical biomechanical model of bones and on various osteosynthesis material models, it calculates and provides the required output results of dilatation (mm) at the site of the fracture inrelation to the applied axial and a lateral force(N). Aim of the study. To examine the budget voltage and deformation of the compressive forces and bending simulator software model in dynamic compression plate (DCP), dynamic locked extension compression plate (LCP), locked intramedullary nail (LIN) and Mitković internal fixator (MIF). Material and methods. CATIA software was used to create a 3D model of the DCP, the LCP, MIF, LIN and for the calculation of stress and strain for the pressure and bending, ANSYS (SCA) software was used. The tested material was loaded by compression forces up to 500 Nand bending forces up to 250N. Results. Results of biomechanical tests on SCA showed that, according to biomechanical stability, LIN was in the first rank, with coefficient ranking KLIN=0.1950. Subsequently, there was TDCP with KDCP=0.1970, MIF with KMIF=0.2238 and LCP with KLCP=0.2394. Discussion. Based on the input data, mathematical model is formed and it uses the entered data, calculates and edits the required results. There is a tendency in today’s world to make the standardization of software testing, so that tested results could be easily applied and interpreted in scientific research purposes. Conclusion. First in rank by biomechanical stability was LIN with coefficient ranking KLIN=0.1950. Subsequently, there was DCP with KDCP=0.1970, MIF with KMIF=0.2238 and LCP with KLCP=0.2394.
