title: The acromioclavicular joint in rheumatoid arthritis.
abstract: The acromioclavicular (AC) joint was clinically and roentgenographically examined in 49 rheumatic patients with painful shoulders. Clinically, the AC joint was tender and painful in about one-third of the shoulders. Roentgenographically, AC changes were encountered in 85% of the shoulders. The AC joint destruction was frequently associated with the glenohumeral joint disease. There was a time-dependent progression of subchondral bone erosion, tapering, and osteolysis of the acromial end of the clavicle corresponding to the duration and/or severity of the rheumatoid disease.
