the influence of the fixation plates on the ostheosynthesis process of the 41-c1 tibia fracture is analysed in this research, by studying the fracture fragments displacements when a compressive load is applied. a cadaveric tibia and a synthetic tibia were experimentally and numerically compared. then, two different fem of fractured tibia were developed: with and without fixation plates, and compression loads were applied to both. kinematical restrictions were employed to simulate fixation plates. the model with fixation plates behaved like a rigid deformable body, while the model without plates collapses.
