Terry Thomas Sign

Terry-Thomas sign is refered to an increase in the scapho-lunate space on an anterio-posterior (AP) radiography or coronal CT of the wrist. The increased distance indicates scapho-lunate dislocations or dissociation (rotary sub-luxation of the scaphoid) due to ligamentous injury. This gap between the scaphoid and lunate bones is more than 3 mm on AP view radiography or coronal wrist CT.

This sign is named after well-known British comic Terry-Thomas (1911 - 1990), who had a large gap between his two front teeth.
