Capitolunate angle

Last revised by Joshua Yap on 27 Nov 2024

The capitolunate angle is the angle between the long axis of the capitate and the mid axis of the lunate on the sagittal imaging of the wrist. In a normal situation it should be <30° in the resting (neutral) position.

The angle is increased in carpal instability such as with a dorsal intercalated segment instability (DISI) and volar intercalated segment instability (VISI). The scapholunate angle is used to differentiate between the two.
