What type of fracture involves anterior displacement of the distal radius?

• A. Boxer's
• B. Smith's
• C. Colles
• D. Torus

Answer: (B)

The fracture that involves anterior displacement of the distal radius is known as a Smith's fracture. This type of fracture typically occurs when a fall on the wrist causes the distal radius to break and displace towards the palmar side or anteriorly. This contrasts with other types of wrist fractures, such as a Colles fracture, which involves dorsal angulation or posterior displacement of the distal radius.

The mechanism of injury for a Smith's fracture is usually a fall onto a flexed wrist or direct trauma when the palm is facing upwards. Understanding the nature of this fracture is crucial for implementing the correct treatment and rehabilitation plan, as the management may differ significantly from other types of wrist fractures.
