Abstract

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.

摘要

对各种内固定板在骨上的锚固情况进行了测试。结果表明,根据板的类型和螺钉数量的不同,存在显著差异。普通圆孔板比动力加压板(DCP)在更高的力作用下更常发生滑动。表面粗糙的动力加压板比表面光滑的同类型板显示出更高的强度。板与骨连接的锚固强度并不与螺钉数量成比例增加。
