Trigger Wrist Phenomenon in Rheumatoid ArthritisOxford
Flexor tendon synovitis in patients with rheumatoid arthritis commonly presents with a carpal tunnel syndrome and a concomitant trigger finger. Triggering at the wrist joint is in this disease an uncommon additional feature. In the two cases reported, histological examination of the tissue has indicated that, as well as chronic synovitis, there was a true rheumatoid nodule present at the wrist joint, either pedunculated or fusiform. The passage of the nodule, with a Click from the proximal side of the transverse carpal ligament to the distal aspect, when the fingers are flexed, creates the sensation, signs and symptoms of a trigger wrist.
