Sažetak
The recent trend in traumatology and orthopaedic surgery has been the development of techniques in minimally invasive surgery and the optimal maintenimi of blood supply to the bone fragments during osteosynthesis. The new plates are made of medical steel and constructed in the same way as the DCP plates but with different groove patterns (reticular, longitudinal, oblique and transversal) on the contact surface with the bone. In this research we first anaham the mechanical properties (bending and torsion) of the new plates as compaired to the classical DCP plates secondly, as compaired to the different groove parza having different contact surface procentage. Depending on the groove pattern the contact surface procentai of the plates varies from 5% for the reticular pattern 19% for the longitudinal, 35% for the oblique, to 58 for the transversal pattern. After getting the data for intact bones, these mechanical properties of the ne plates were compaired to the measurementes for de intact bones. In the next part of the research the me plates were fixed to the fractured bones and tested for its mechanical properties. The experiments showie that all four types of the new plates are more liable bending and torque then the classical smooth plates (beeing thiner due to the grooved surface), but are considerably stronger then the intact bones, allowing conditions for a stabile osteosynthesis. Testing the new plates fixed to fractured bones, the experiment showed that bending allways occurs in the position the screw fixing the plates to the bone, the fixed never broke while the intact bones broke subjected forces of much lesser intensity.
