Der zementfreie CLS-Titangeradschaft - Langzeitergebnisse, Indikationen und Limitationen

. Abstract The uncemented CLS stem has been in clinical use since 1985. With over 350000 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 co-rundum 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 de-formities.
