The aim of implantation of cementless hip prostheses is vital ingrowth of bone into the structured metal surface of the implant. Since the 1960s several implants with surfaces made of cobalt-based alloys have been produced for this purpose. In the 1980s a novel hip endoprosthesis with a spongiosa-metal surface was introduced. The three-dimensional ingrowth of bone tissue into the structured surface of the implant could be demonstrated both histologically and using scanning electron microscopy (SEM). These implants made of cobalt-based alloys can also be used in endo-exo prostheses. Titanium implants with a microstructured surface have also been used and very good osseintegration of the surface was also demonstrated by histomorphology. The optimization of the surface and design of the prostheses plays an increasingly more important role in the field of revision endoprostheses.
非骨水泥型髋关节假体植入的目的是使骨组织紧密长入植入物的结构化金属表面。自20世纪60年代以来,已经生产了几种用于此目的的表面由钴基合金制成的植入物。20世纪80年代,一种具有松质骨-金属表面的新型髋关节假体被引入。骨组织向植入物结构化表面的三维长入在组织学和扫描电子显微镜(SEM)下均得到证实。这些由钴基合金制成的植入物也可用于内外联合假体。具有微结构化表面的钛植入物也已被使用,并且组织形态学也证实了其表面具有非常好的骨整合。假体表面和设计的优化在翻修假体领域中发挥着越来越重要的作用。
