Carpal alterations in adult-onset Still disease, juvenile chronic arthritis, and adult-onset rheumatoid arthritis: comparative study.
A specific pattern of pericapitate involvement of the wrist has been described in the rheumatologic literature as characteristic of adult-onset Still disease (AOSD), a relatively rare disorder that is often diagnosed by exclusion after extensive and frequently invasive tests. To evaluate the potential diagnostic value of carpal radiography in suspected cases of AOSD, a retrospective blinded analysis of 48 patients (16 each with AOSD, juvenile chronic arthritis, and adult-onset rheumatoid arthritis) was performed. Pericapitate articular alterations without radiocarpal involvement were found to be distinctly unusual among patients with rheumatoid arthritis but frequent in the setting of AOSD. In juvenile chronic arthritis severe pericapitate involvement also occurs frequently but is more likely to be associated with interosseous fusion and severe pancompartmental disease.
