41-year-old patient:
Pain to the anatomical snuffbox after a rollerblade accident (hyperextension wrist trauma).

Distal pole fracture

Scaphoid fracture

Linear hypodensity

Non-displaced fracture of the distal third (distal pole) of the scaphoid bone.

Waist fracture

Scaphoid fracture

A scaphoid waist fracture would be here.

Proximal pole fracture

Scaphoid fracture

A proximal pole fracture would be here.

Scaphoid

Here are the contours of the scaphoid bone.

Lunate

Here are the contours of the lunate bone.

Scapholunate angle

The integrity of the scapholunate and the lunotriquetral ligaments is assessed by measuring the scapholunate angle. This angle is normal here. If the scapholunate ligament is incompetent or if the scaphoid is fractured at its attachment, the scaphoid will rotate dorsally and the scapholunate angle will be greater than 70° (deformity known as a DISI for "dorsal intercalated segmental instability"). If the lunotriquetral ligament is incompetent, the scaphoid and the lunate bones will rotate into a volar position, reducing the scaphonulate angle to less than 30° (deformity known as a VISI for "volar intercalated segmental instability").

Scapholunate distance

If the scapholunate ligament is incompetent, the distance between the scaphoid and the lunate bones will increase (the normal is less than 2 mm).
