A distal radius fracture with ventral angulation is known as Smith's fracture.

• A. Colles
• B. Smiths
• C. Monteggia
• D. Galeazzi

Answer: (B)

A distal radius fracture with ventral (palmar) angulation is Smith's fracture. The key detail is the direction of the distal fragment’s bend: it tilts toward the palm, which is the opposite of the dorsal tilt seen in a Colles fracture. This ventral angulation often results from a fall on a flexed wrist or a blow to the back of the hand. Other injuries listed involve different patterns: a Colles fracture shows dorsal displacement of the distal radius, while Monteggia and Galeazzi injuries involve the ulna or the distal radioulnar joint, not just ventral angulation of the distal radius. Thus the described mechanism and displacement point to Smith's fracture.
