[Biomechanical investigations about the transfer of axial load in different forms of plate-osteosynthesis (author's transl)].

The anchorage of various internal fixation plates on bones was tested. The results showed significant differences depending on the type of plates and the number of screws. Normal round hole plates slipped at higher forces more often than dynamic-compression plates (DCP). DC-plates with a rough surface revealed a higher strength than the same plates with a smooth surface. The anchorage strength of the plate-bone connection does not increase proportionally to the number of screws.
