Der zementfreie CLS-Titangeradschaft - Langzeitergebnisse, Indikationen und Limitationen

Zusammenfassung

Seit 1985 wird der zementfreie CLS-Geradschaft implantiert und ist mittlerweile mit über 350 000 Implantationen einer der am häufigsten implantierten zementfreien Schäfte in Europa. Selbst bei schwierigen anatomischen Verhältnissen und in den Händen von verschiedenen Operateuren mit unterschiedlichem Ausbildungsstand hat sich die femorale Versorgung mit diesem System bewährt. In diesem Beitrag sollen die Langzeitergebnisse, Indikationen und Limitationen mit diesem zementfreien, korundgestrahlten Titangeradschaft nach bis zu 20 Jahren dargestellt werden. Die Implantation des zementfreien Geradschaftes ist aus der Sicht der Autoren deutlich einfacher und weniger anfällig für technische Fehler als ein gut zementierter Prothesenschaft und bietet damit verlässlichere und konsistentere Langzeitergebnisse selbst bei schwierigen Deformitäten.

Abstract

The uncemented CLS stem has been in clinical use since 1985. With over 350 000 implantations it has become one of the most frequently implanted uncemented femoral hip stems in Europe. Even in femoral deformities and in the hands of surgeons with differing levels of surgical training the long term results have been demonstrated to be outstanding. In this article the long term results, indications and limitations of a straight corundum blasted titanium femoral component with a follow-up up to 20 years are discussed. The insertion of an uncemented straight femoral component is a lot simpler and susceptible to less sources of error than a well cemented hip stem. It can provide more consistent and durable results even in femoral deformities.
