X-ray

Asymmetric widening of the right scapholunate interval, right 3 mm, left 1 mm. 

A needle was inserted into the right radioscaphoid joint. Iodinated contrast mixed with gadolinium was injected into the right radioscaphoid joint. The contrast extended into the mid carpal joints suggesting a disruption of the scapholunate ligament. The patient was then sent to MRI.
