Four cases of trigger wrist induced by finger motion are reported. The cause of trigger wrist induced by finger motion was a rheumatoid nodule in one case, giant cell tumor of the flexor tendon sheath in one case, partial laceration of the flexor digitorium superficialis tendon in one case, and lipofibroma in one case. Triggering or snapping at the wrist is also induced by motion of the wrist and forearm. Reported cases were also analyzed and the clinical entity of the true trigger wrist and differential diagnosis were discussed.
