What type of fracture is characterized by dorsal displacement of the distal fragment?

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

Answer: (B)

A Colles fracture is characterized by dorsal displacement of the distal fragment. This type of fracture is commonly located in the distal radius, typically occurring when an individual falls onto an outstretched hand with the wrist in extension. The mechanism of injury leads to the distal fragment being displaced in a dorsal direction, resulting in a classic "dinner fork" appearance when viewed radiologically.

Understanding the nature of this fracture is crucial in clinical practice, as it often requires specific management and can have different implications for recovery than other types of wrist fractures. Recognizing the characteristic dorsal angulation of the distal fragment helps healthcare professionals in diagnosing and implementing the appropriate treatment strategies to ensure optimal recovery for the patient.
