Painless Synovitis in Patients With Longstanding Rheumatoid Arthritis

There is a group of patients with rheumatoid arthritis (RA) that suffer from chronically painless synovitis in the hands. The objective of this study is to compare painless synovitis with painful synovitis according to the sonographic (Gray-scale and power Doppler) findings. A sonographic examination (Gray-scale and power Doppler) will be done to evaluate metacarpophalangeal joints of patients without local painful and will be a comparison with patients with local painful.
