A Doheny fracture is a fracture of which bone with outward displacement?

• A. Fracture of the radius with outward displacement.
• B. Fracture of the navicular bone in the wrist.
• C. Multiple finger fracture.
• D. Hairline fracture of the os calcis.

Answer: (A)

A Doheny fracture refers to a fracture of the radius with outward displacement of the distal fragment. This term identifies both the bone involved (the radius) and the direction the broken piece moves—outward from the ulna and toward the outer side of the wrist. In wrist/forearm injuries, the pattern of displacement helps distinguish fracture types, with this one specifically describing the radius when the distal fragment shifts outward. The other options involve different bones or parts of the body (navicular/scaphoid in the wrist, fingers, or the calcaneus in the foot) and do not match this eponym.
