Which projection is specifically designed to evaluate the scaphoid bone, often performed with ulnar deviation?

Explanation:
The key idea is visualization of the scaphoid in its true profile. A dedicated scaphoid projection does just that by positioning the wrist in ulnar deviation (often with slight flexion) so the scaphoid sits between the radius and other carpal bones without overlapping. This alignment reduces foreshortening and bone overlap, making fractures—especially those at the waist or proximal pole—easier to detect, even if initial standard views look normal. The regular AP, lateral, and oblique wrist views don’t optimize the scaphoid’s silhouette and can miss occult fractures due to overlapping structures. That’s why this special scaphoid view, performed with ulnar deviation, is specifically designed for evaluating the scaphoid.
