There is an intra-articular radial styloid fracture. Importantly, there is widening of the scapholunate distance (Terry Thomas sign) consistent with scapholunate dissociation. A scapholunate torn ligament does not heal on its own. If left untreated, a torn ligament typically leads to arthritis over time. This is because the bones of the wrist are no longer held in normal alignment.

The scapholunate is an interosseous carpal ligament that provides stability to the proximal carpal row. It consists of dorsal, proximal and palmar segments that bridge the scaphoid and lunate.

The scapholunate angle is the angle between the long axis of the scaphoid and the mid axis of the lunate on the sagittal imaging of the wrist. In a normal situation, it should be between 30 and 60 o in the resting (neutral) position.

There is increased distance of greater than 5 mm (black arrow) between the scaphoid (S) and the lunate (L) producing the so-called Terry Thomas or David Letterman sign.

Materials and Methods: Retrospective case series of 11 patients with a mean age of 45 years were treated by the senior author 7 months after SL injury. The SL joint cartilage was removed, the SL joint was stabilized temporarily with 2 Kirshner wires for 8 weeks and ECRL tenodesis to scaphoid dorsally.
