- Scapho-lunate angle
The scapholunate angle is the angle between the long axis of the scaphoid and the mid axis of the lunate on sagittal imaging of the wrist. In a normal situation, it should be between 30 and 60o in the resting (neutral) position.
The scapholunate angle is abnormal in carpal instability:
- increased in scapholunate dissociation
- increased in dorsal intercalated segmental instability with increased capitolunate angle
- decreased in volar intercalated segmental instability with increased capitolunate angle
