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.
研究了应用AO小型接骨板进行加压接骨术时，预弯和预应力对前臂骨骼的影响。通过实验研究了所需的预应力、预弯角度以及骨折部位由此产生的压缩中心。这些实验在新鲜尸体的尺骨和桡骨上进行。此外，在垂直骨干截骨处应用具有不同预弯角度和不同预应力的小型接骨板后，进行了稳定性测试。使用有限元方法对所进行的实验进行了理论分析。
