Remember to evaluate for any rotational deformity when evaluating patients with a phalanx fracture.
The easiest way to do this is to have the patient flex all their fingers. They should all point to the scaphoid. If a finger deviates or overlaps another finger there is a rotational deformity. One should also make sure that all the nailbeds align.

Even if the finger is reduced otherwise, persistent rotational deformities should be referred to a hand surgeon for consideration of corrective surgery.
