Abstract

Cementless anchoring of orthopedic implants requires specific physical characteristics of the implant surface. While the primary implant stability is defined by the surface friction, the definite implant stability depends on the biological integration, which is correlated to the porosity of the implant. Different coating materials and techniques have been developed to improve both parameters, friction and porosity, e.g. sintered balls, fibre metals, plasma spray coatings and titanium blasting. Nevertheless, the achievable porosity and thickness of coatings have shown to underlie fundamental limitations.
