Apport des critères doigts — orteils dans le diagnostic précoce du rhumatisme psoriasique

Abstract

Purpose To assess the value of Fournie's radiological criteria “fingers and toes” in the early diagnosis of psoriatic arthritis. Materials and methods 47 patients with psoriatic arthritis were studied retrospectively. Clinical and radiological features at the hands and fingers were assessed. Radiographic analysis was performed using Fournie's criteria. Results Of 47 patients studied, 25 patients developed hand and finger involvement. Asymmetrical joint distribution was observed in 76% of cases. Distal interphalangeal arthritis was noted in 60% of cases. Nail lesions were present in 11 cases and dactylitis in 3 cases. Eight patients had erosions of the distal interphalangeal joints. Osteolysis with pencil-in-cup deformity wasa noted in 3 cases. Ankylosis of interphalangeal joints was found in 7 cases and acro-osteolysis in 3 cases. Conclusion Psoriatic arthritis frequently affects the small joints of the hands and fingers. Asymmetrical and distal interphalangeal joint involvement are a characteristic feature of this arthropathy. Some radiological lesions are suggestive and contribute to the early diagnosis of psoriatic arthritis.
