TI  - Expectations and outcome of a scientifically developed hip prosthesis in 170 hips 
      with a follow-up of 5-12 years.

AB  - Roentgen stereophotogrammetric analysis (RSA) is commonly used to assess 
      prosthetic stability as a predictor of the long-term clinical outcome of new 
      total hip systems. Although the RSA technique is very accurate, it may not be 
      trivial to interpret migration rates into clinical outcome, as critical migration 
      rates depend heavily on the design of the prosthesis. In the present study we 
      describe the clinical results of the Scientific Hip Prosthesis (SHP), which had 
      unexpectedly high migration values in a clinical RSA study. We evaluated the 
      clinical results of a single surgeon study consisting of 170 hips with a 
      follow-up of 5-12 years (mean: 83 years). The survival rate was 98.8% at ten 
      years for aseptic loosening of the stem. This study therefore indicates that a 
      prosthetic design may function clinically rather well although relatively high 
      migration rates have been reported. The prediction of clinical survival of new 
      prosthetic components remains a challenging task and the interpretation of 
      migration rates with new designs should be considered with much caution.
