David Letterman Sign

A finding on a plain film of the wrist characterised by a marked widening (a gap of 3 mm or more) of the joint space between the scaphoid and lunate, which is seen in patients with rotatory subluxation of the scaphoid (scapholunate dislocation). Untreated, the subluxation is associated with chronic wrist pain and disability. The widened space has been fancifully likened to the dental diastema (gap teeth) of American talk show host David Letterman, as well as American model Lauren Hutton and British comedian Terry Thomas, for whom it was originally named
