Introduction: Artificial models can be useful at approximate and qualitative research, which should give
the preliminary results. Artificial models are usually made of photo-elastic plastic e.g.. juvidur, araldite
in the three-dimensional contour shape of the bone. Anatomical preparations consist of the same heterogeneous, structural materials with extremely anisotropic and unequal highly elastic characteristics,
which are embedded in a complex organic structure. The aim of the study: Examine the budget voltage
and deformation of: dynamic compression plate (DCP), locking compression plate (LCP), Mitkovic internal
fixator (MIF), Locked intramedullary nailing (LIN) on the compressive and bending forces on juvidur and
veal bone models and compared the results of these two methods (juvidur, veal bone). Material and
Methods: For the experimental study were used geometrically identical, anatomically shaped models
of Juvidur and veal bones diameter of 30 mm and a length of 100 mm. Static tests were performed with
SHIMADZU AGS-X testing machine, where the force of pressure (compression) increased from 0 N to
500 N, and then conducted relief. Bending forces grew from 0 N to 250 N, after which came into sharp
relief. Results: On models of juvidur and veal bones studies have confirmed that uniform stability at the
site of the fracture MIF with a coefficient ranking KMIF=0,1971, KLIN=0,2704, KDCP=0,2727 i KLCP=0,5821.
Conclusion: On models of juvidur and veal bones working with Shimadzu AGS-X testing machine is best
demonstrated MIF with a coefficient of 0.1971
