[In vitro studies on various PMMA bone cements: a first comparison of new materials for arthroplasty].

Aim: Two clinically established PMMA bone cements (Refobacin Palacos R and Palacos R + G) and two newer cements not yet in widespread clinical use (Refobacin Bone Cement R and SmartSet GHV) were tested in vitro for practically relevant differences.

Methods: The tests included chemical analyses, handling properties and testing according to the ISO standard for PMMA bone cements.

Results: The results obtained indicate clearly that the copolymers used in Refobacin Bone Cement R and SmartSet GHV differ from those used in the Palacos cements.
