In ulnar deviation, the scaphoid can be assessed for fractures. The cost for the early MRI approach appears to be equivocal, but there have been no controlled studies concerning outcomes.12 Because nondisplaced fractures heal well, a study would be needed to confirm if early MRI adds anything to the treatment of nondisplaced fractures.
