title: Outcome of custom-made IMP femoral components of total hip arthroplasty: a follow-up of 15 to 22 years.
abstract: A total of 1659 primary THAs using a cemented custom-made intra-operative manufactured prosthesis (IMP)-stem were studied. The end point for survival was defined as revision of the stem for any reason. Revision arthroplasty was performed in 49 cases. The IMP-stems had a revision free 20-year survival rate of 95.5%. Revisions were performed mainly because of aseptic loosening. There were no drawbacks like increased infection risk due to the prolonged surgical time needed for the intra-operative production of the stem. These data provide evidence that the cemented IMP-stem is able to provide good long-term results.
