title: Failure of the Christiansen hip. Survival analysis of 265 cases.
abstract: Totally, 265 primary Christiansen total hip arthroplasties were followed clinically and radiographically for a median of 6 years. The operations were performed for arthrosis in 220 cases, failed fracture in 23, and rheumatoid arthritis in 13. The influence of 11 presumed determinants on the radiographic outcome was studied. In all, 96 hips were exchanged because of aseptic loosening, 35 stems were loose, and 210 sockets were definitely or probably loose at the last radiographic examination. The survivorship analyses revealed the probability of having a radiographically intact stem after 10 years as 67 percent and for the socket 0 percent. None of the 11 determinants influenced the radiographic outcome.
