[Biochemical and mathematical studies of the pre-bending and pre-stressing of the small fragment DC plate].
The effects of prebending and prestressing in compressional osteo-synthesis with application of the AO small-fragment DC plate on the bones of the forearm were examined. The necessary prestress force, the angle of prebending and the resulting center of compression in the fracture site were experimentally examined. These experiments were performed on fresh cadaver bones using the ulna and the radius. Additionally, after applying small-fragment DC plates with varying angles of prebending and varying forces of prestressing on perpendicular shaft osteotomies, stability tests were carried out. A theoretical analysis of the experiments performed was computed using the finite element method.
