Zusammenfassung

Hintergrund

Bei Zementaugmentation und Knochenersatz finden Materialien mit unterschiedlichen Eigenschaften Anwendung.

Fragestellung

Zementaugmentation und Knochenersatzmaterialien sind Gegenstand aktueller Forschung. Die Bewertung neuer Erkenntnisse erlaubt ihren spezifischen Einsatz.

Material und Methoden

Selektive Literaturrecherche und Zusammenstellung experimenteller Ergebnisse zu Zementaugmentation und Knochenersatz.

Ergebnisse

Augmentation und Knochenersatz sind feste Bestandteile der aktuellen Unfallchirurgie. Trotz intensiver Erforschung weisen alle Materialien spezifische Nachteile auf. Die Zementaugmentation von Implantaten verstärkt nicht nur deren Verankerung, sondern verändert auch den Versagensmodus.

Schlussfolgerung

Besonders im osteoporotischen Knochen hat die Zementaugmentation großes Potenzial. Im lasttragenden Bereich bleiben weiterhin Acrylzemente der Standard. Keramikzemente sind in nichtlasttragenden Bereichen zu bevorzugen. Ihre Kombination mit resorbierbaren Metallen bietet ein noch weitgehend unerforschtes Potenzial. Die virtuelle Biomechanik kann die zielgerichtete Anwendung von Zementaugmentationen verbessern.
