What is a Doheny fracture characterized by?

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

Answer: (B)

A Doheny fracture is characterized by multiple fractures of the fingers, specifically involving the phalangeal bones. This type of fracture typically results from high-impact trauma, often seen in sports-related injuries or accidents where the fingers are subjected to extreme forces.

The other options represent different types of fractures:

• The fracture of the navicular bone in the wrist (option A) pertains to a carpal fracture common in sports where wrist injuries occur, like in falls on an outstretched hand.

• The fracture of the radius with outward displacement (option C) may refer to a specific kind of distal radius fracture, common in falls but distinct from the multi-finger involvement of a Doheny fracture.

• The hairline fracture of the os calcis (option D) describes an injury to the heel bone, often resulting from repetitive stress or landing from a jump.

Each of these choices highlights a specific type of injury, emphasizing the unique nature of a Doheny fracture as involving multiple finger fractures.
