Randomized controlled trial using two types of hip stems, SL PLUS MIA (control group) and SL
PLUS (study group).
We compare primary and secondary stability of both hip stems for radiographic outcome using
EBRA (Ein-Bild-Roentgen-Analyse) after a two year follow-up period.
Further, we compare all differences in clinical outcome using Harris Hip Score, Oxford hip
score and radiographic findings.
