What is the most common fracture-dislocation of the wrist joint?

• A. Colles Fracture
• B. Scaphoid Fracture
• C. Smith Fracture
• D. Barton's Fracture

Answer: (D)

Wrist fracture‑dislocations occur when a force not only breaks a bone but also disrupts the joint surface. The Barton pattern is the classic example: an intra‑articular fracture of the distal radius with dislocation (or subluxation) of the radiocarpal joint. That combination of a fracture extending into the joint and an accompanying joint dislocation is what defines a fracture‑dislocation, and it is the pattern most typically described as the wrist’s fracture‑dislocation injury. Other wrist injuries like Colles and Smith are fractures of the distal radius without radiocarpal dislocation (Colles is a dorsal angulation; Smith is a reverse pattern with palmar angulation). A scaphoid fracture is a carpal bone fracture without radiocarpal dislocation. Thus, Barton’s fracture best fits the description of a fracture‑dislocation of the wrist joint, making it the most common pattern in that specific category.
