Abstract

3 Chernivtsi regional clinical hospital, Ukraine Abstract. There was concerned suggested methodology of optimal choice variant positioning of fixing and blocking screws on plate body for fixing bone fragments in cases of transverse diaphyseal fractures to prevent rotational forces. It was described the possibility to determine optimal positioning of fixing and blocking elements in cases of using 3, 4, 5 screw fixings on each plate side. The finite elements method allows appreciating parameters of stress-stain state fixing device material for various sets of allocation fixing and blocking screws on plate body. Enumeration of possibilities combinations of blocking and fixing screws positions were reviewed by mean of combinatory apparatus. The comparable analysis of derived calculation results was performed in similar study for plate osteosynthesis of identical fracture with strain-compression deformities. Results of performed research allow elaborating practical recommendations for orthopaedic doctors and improving quality of treatment patients.
