c/o severe pain in the right wrist. Frontal view of the wrist showed increase in scapholunate distance (arrow). It measures 3.5mm. Other intercarpal joints measures about 1.5mm only. This is consistent with Terry-Thomas sign and indicates scapholunate dissociation. The rest of the bone and… A grip compression view or wrist in ulnar deviation may be necessary in addition to PA/lateral views.

The scaphoid usually rotates into flexion, and the lunate rotates into extension. This is apparent on plain static radiographs. Scapholunate dissociation is when the small bones in the wrist (the scaphoid and the lunate) move excessively in relation to one another. Physiotherapy is an important part of scapholunate dissociation rehabilitation.

Scapholunate dissociation is a spectrum of rotational abnormalities that is dependent on the severity of the injury and the resulting involvement of ligamentous abnormalities, and is one of the most common forms of carpal instability. Scapholunate (SL) dissociation is part of a spectrum of traumatic carpal bone instabilities and is defined as disruption of the ligamentous complex holding the scaphoid and lunate together.

Importantly, there is widening of the scapholunate distance (Terry Thomas sign) consistent with scapholunate dissociation. Scapholunate dissociation (SLD) is disruption of the ligamentous connection between the scaphoid and lunate (Figures 3). 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. When the ligament complex tears, the scaphoid tends to flex while the lunate extends, creating translational and rotational instability between the two. Scapho-lunate ligament is an important ligament that holds the scaphoid and lunate bones together.
