Which statement about Colles fracture is true?

• A. It involves the radius
• B. It involves the ulna
• C. It involves the tibia
• D. It involves the fibula

Answer: (A)

Colles fracture centers on the distal radius near the wrist. It’s a fracture of the radius, usually from a fall on an outstretched hand, leading to dorsal (posterior) displacement of the distal fragment and the characteristic dinner-fork deformity. The leg bones (tibia and fibula) aren’t involved in this wrist injury, and while the ulna is the other forearm bone, the defining feature of a Colles fracture is the distal radius fracture. So the statement that it involves the radius is true.
