Safety and Efficacy of the SL PLUS and the SL PLUS MIA Hip Stem

This study is a monocentric study, randomized and controlled including two types of hip stems: SL PLUS MIA (control group) and SL PLUS (study group). Each group will include 45 patients where a number of 5 patients for each group calculated extra in case of loss. Patients will be followed after * 6 weeks * 6 months * 12 months * 24 months. Radiographs are taken in a-p and lateral view using a standard protocol. Primary and secondary stability of both hip stems will be analyzed using the EBRA software (Ein-Bild-Roentgen-Analyse, University of Innsbruck, Austria) after the completion of the two year follow-up. Further, we compare all differences in clinical outcome using Harris Hip Score, Oxford hip score and radiographic findings such as radiolucent lines.
