In a normal situation, it should be between 30 and 60 o in the resting (neutral) position. The scapholunate angle is abnormal in carpal instability: increased in scapholunate dissociation. 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. Widening of the scapholunate joint space >3mm Known as Terry-Thomas sign (or David Letterman sign) Rotary subluxation of the scaphoid Lateral view: Scapholunate angle >60 degrees; PA view: Cortical ring sign (circular cortex of the bone is more prominent) Dorsal intercalated segment instability Scaphoid Cortical Ring Sign. When there is rotation of the scaphoid as can occur with scapholunate dissociation (widening of distance between scaphoid and lunate to greater than 3 mm), (yellow arrow), a ring-shaped density can appear as a sign of foreshortening (white arrow).

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. 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. The scapholunate angle is abnormal in carpal instability: increased in scapholunate dissociation Widening of the scapholunate joint space >3mm Known as Terry-Thomas sign (or David Letterman sign) Rotary subluxation of the scaphoid Lateral view: Scapholunate angle >60 degrees; PA view: Cortical ring sign (circular cortex of the bone is more prominent) Dorsal intercalated segment instability A needle was inserted into the right radioscaphoid joint.
