The bone can be protected against excessive stress if the plate is properly adapted to the surface of the contact area between plate and bone, thus ensuring good and longlasting repositioning of the fracture. The article describes an in-vitro method for the quantitative evaluation of the contact area between plate and bone in osteosynthesis. With four different bones and the requisite plates, six expert surgeons were able to obtain an area of contact between plate and bone which varied between 13 and 60%, the average being 32%. The available data allow us to conclude that the peak loads of pressure occurring with small contact areas may be so great that they exceed the maximum compressive strength of the bone.
如果接骨板与骨之间的接触区域表面适配得当，骨就能免受过度应力，从而确保骨折得到良好且持久的复位。本文描述了一种体外方法，用于定量评估骨接合术中接骨板与骨之间的接触面积。使用四块不同的骨头和所需的接骨板，六位专业外科医生得到的接骨板与骨之间的接触面积在13%至60%之间变化，平均为32%。现有数据使我们能够得出结论，小接触面积时出现的压力峰值负荷可能非常大，以至于超过了骨的最大抗压强度。
