Romulus Fabian Tatu, Virgil Ivaschescu, Florina bojin, Mihai Hurmuz, Carmen Tatu A Mechanical Vibration Method Used to Investigate the Evolution of Fractures Fixed with Biocompatible Materials


Abstract:
Difficulty to objectively determine the moment of bone fracture consolidation by classical imaging methods makes necessary the development of a method that will allow establishing, by objective criteria, the moment in which biomechanical loading of the injured bone segment may be permitted. We propose a method based on the approximation between bone diaphysis and a beam, analysing its behaviour under frequency excitation at one end and measuring the vibrations at the other end. Variation of parameters measured in the structurally sound structures compared to the fractured ones, as well as the possibility to analyse their evolution in the presence of osteosynthesis materials used for the surgical treatment of fractures is ascertained. The existence of composite plastic materials of which the used anatomical bone mould for this experiment is made simulates the real pathological situation, which allows extending the determinations to clinical cases. Key words: bone, fracture, mould, polyurethane, osteosynthesis material, composite material
