PROGRESSION OF HIP DISEASE IN RHEUMATOID ARTHRITIS*

Department of Rheumatology and Oxford Rehabilitation Research Unit, Nuffield Orthopaedic Centre Headington, Oxford
Examination of the serial hip radiographs of patients with osteoarthrosis and rheumatoid arthritis undergoing total joint replacement has allowed the estimation of rates of progression using two measurements. One of these measurements, an index of acetabular thickness, correlates with the use of systemic corticosteroid therapy and demonstrates a more rapid deterioration. No correlation with the severity of inflammatory joint disease and the rate of progression could be found. A high incidence of avascular necrosis is seen using standardized criteria. A difference in the rate of deterioration between osteoarthrosis and rheumatoid arthritis is shown. The formation of protrusio acetabuli and the effects of indomethacin are discussed.
