[Fundamental biomechanic problems on osteosynthesis (author's transl)]

By means of compression plate osteosynthesis, of the lateral tension band and of the treatment with external chucks the main demand for stability of osteosynthesises is derivated: by adjustified, in the resultant axial tension of the metal implantats is to produce only pressure in the entire fracture zone without detrimental osteosynthesis induced excentric powers. The joint biomechanic aspects of the three methods are worked out.
