Capitolunate angle

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 less than 30o in the resting (neutral) position.

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