The Girdlestone pseudarthrosis in the treatment of infected hip replacements.

The results of 78 resections of the head and neck of the femur (Girdlestone pseudarthrosis) in patients with infected hip replacements were studied. The mean follow-up was 5 years. At the time of the resection, gram-positive organisms were found in 53% of the cases, gram-negative in 33%, and in 12% there were mixed flora. The Girdlestone pseudarthrosis controlled the infection in 86% and achieved satisfactory relief of pain in 83%. The mean shortening of the limb was 4.1 cm and every patient needed some type of external walking aid. We found no correlation between the type of organisms and the persistence of infection, nor between shortening and the functional results. The Girdlestone pseudarthrosis is an acceptable method of controlling infection and relieving pain after infection of a total hip replacement.
