MRI shows subtle edema involving the dorsal aspect of the lunate. Moreover, there is slight posterior displacement of the capitate compared to the distal radius, the luno-capitate angle is > 30°. The lunate is displaced dorsally (the anterior apex of the lunate points more dorsally). Harder to measure on MRI, the scapholunate is also greater than 60°.
Moreover, there is a slight increase in the scapholunate distance dorsally, near the lunate contusion, compatible with scapholunate ligament tear.
This patient also has a flexor carpi radialis tenosynovitis.
