Purpose:
To date there is a lack of long-term results of anatomic hip stems in the literature. In this context we present our 10-year results with the hip stem "Euroform".
Methods:
In a retrospective cohort study 90% of the 51 stems implanted in our institute in the years 1993/94 51 stems were reexamined. Of them 39 were implanted cement-free while 11 were cemented.
Results:
After 10 to 12 years no revision surgery of the cement-free stems was necessary or performed because of stem problems, in one case of a cemented stem revision was done because of cup problems. The survival rate for the complete prostheses was 97.5% after 10 years and 92% after 12 years. The revision surgery was done for cup problems. The satisfaction rate was "1.9" (according to the German school ranking system), the Merle d'Aubigné score was "good" (>10 points). However, one problem was the high rate of PE deterioration which depended on the inclination.
Conclusion:
Both the cemented and the cement-free forms of the "Euroform" stem gives good long-term results. The longevity of the prostheses is limited by polyethylene wear.
