title: The uncemented primary Bicontact stem in revision total hip arthroplasty in young patients.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the uncemented primary Bicontact stem (B.Braun-Aesculap, Tuttlingen, Germany) as a possible adequate alternative to other revision systems in revision total hip arthroplasty.
  
  
  METHODS
  Twenty patients aged up to 58 years (34-58 years, mean age 5.7 +/- 5.8 years) with minor bone defects underwent a revision total hip arthroplasty with the uncemented primary Bicontact stem. The patients were assessed clinically and radiologically at follow-up (follow-up: 8.0 +/- 3. years).
  
  
  RESULTS
  The postoperative Harris Hip Score, Motion and Pain Score improved significantly. There was only one further revision in these patients because of infection and only one case with mild stress shielding.
  
  
  CONCLUSIONS
  The uncemented primary Bicontact stem seems to be a good alternative to other revision systems in total hip revision arthroplasty in young patients.
