Radiologic changes in temporomandibular, hand, and foot joints of patients with rheumatoid arthritis.
Radiologic changes in the temporomandibular joint (TMJ) and in the joints of the hand and foot were recorded for 90 adult patients with rheumatoid arthritis. The severity of the changes was graded according to the Larsen classification of six grades (O to V), and mainly erosive changes were recorded. The assessment of the radiographs was performed with the aid of reference films. The radiologic changes in the TMJs corresponded to grade II (definite early abnormality) and paralleled those of most of the metacarpophalangeal and metatarsophalangeal joints. The most severe changes were localized to the wrists, with a median grade of III (moderate destructive abnormality). The severity of the changes was similar on the right and left sides of the TMJ. We conclude that TMJ involvement in patients with rheumatoid arthritis is severe and warrants a thorough initial clinical examination. Such a strategy will facilitate the diagnosis and treatment of TMJ changes in the early stages of the disease.
