Fracture of distal end of the radius with outward displacement?

• A. Colles Fracture
• B. Bennett Fracture
• C. Smith Fracture
• D. Chauffeur's Fracture

Answer: (A)

Fracture of the distal radius with outward displacement refers to Colles fracture, where the distal fragment is displaced dorsally (toward the back of the hand) after a fall on an outstretched hand with the wrist extended. This tilt of the distal fragment, often with some radial deviation, gives the classic dinner-fork appearance on X-ray. It’s typically an extra-articular fracture of the distal radius and is distinguished from Smith fracture, which has palmar (volar) displacement of the distal fragment due to a fall on a flexed wrist. Bennett fracture involves the base of the first metacarpal at the thumb, and Chauffeur’s fracture is a fracture of the radial styloid.
