Five patients with rheumatoid arthritis and no previous hip joint disease developed an acute disabling arthritis in one hip joint. Roentgenograms were negative and synovial fluid from the hip joint was inflammatory, but no crystals were seen and cultures were negative. Four of the five patients responded rapidly to intra-articular corticosteroids, and none of the five has had further hip joint symptoms during a mean follow up period of two years.
