BACKGROUND: Rheumatoid arthritis is a multi-systemic disease which affects all synovial joints. Compromised bone quality may have a negative impact on prosthesis incorporation after total hip replacement, resulting in an increased risk of aseptic loosening and early implant failure. MATERIALS AND METHODS: Between 2002 and 2007, 49 patients (age 29-80 years) underwent total hip replacement. Radiographs were evaluated for signs of loosening or failure. RESULT: Of the 49 hips, there was one case of stem subsidence, and one case of aseptic loosening. There were no revisions in the current series. Complications included eight (16.3%) intra-operative calcar fractures, which healed uneventfully. CONCLUSION: We report satisfactory radiological results, and revision rate in a group of rheumatoid patients at mid-term review following total hip replacement with uncemented femoral stems.
