Abstract

Die Erfindung betrifft einen sogenannten Knochenzement, z.B. auf der Basis von Polymethylmethacrylat, Polystyrol bzw. Copolymeren, mit einer globularen, vorzugsweise kugeligen Formgestalt der die pulverförmige Komponente bildenden Partikel z.B. aus Polymerisat, Additiven und/oder Röntgenkontrastmittel, sowie ein vorteilhaftes Röntgenkontrastmittel selbst, wobei diese Partikel im wesentlichen relativ grosse, einheitliche Abmessungen aufweisen und in Mischung mit dem Monomer vorzugsweise eine hexagonal dichteste Kugelpackung bilden. Die Erfindung betrifft ferner einen Knochenzement mit einem physiologisch besser akzeptablen Beschleuniger und mit einem speziell auf die Partikel aufgebrachten Katalysator. Die entsprechenden Knochenzementmischungen sind problemlos und ohne die Gefahr von Lufteinschlüssen anmischbar, die erforderliche Menge an Monomer ist reduziert, die Wärmeabgabe und der Volumensschwund während der Polymerisation sind niedriger, die Biegezugfestigkeit des ausgehärteten Produkts mindestens gleich oder besser, und die abrasive Wirkung vermindert. Daneben wird ein erniedrigter Restmonomergehalt erwartet.
