The Terry Thomas sign refers to an increase in the scapholunate space on an AP radiograph of the wrist .  The increased distance indicates scapholunate dissociation (rotary subluxation of the scaphoid) due to ligamentous injury.  The sign is named after Terry Thomas who had large gap between his two front teeth, also called as David Letterman sign.
