Colles fracture involves which bone?

Explanation:
Colles fracture involves the distal radius. It typically happens when you fall on an outstretched hand, causing the distal radius to fracture with the fragment displaced dorsally (toward the back of the hand). This produces the classic dinner-fork deformity on X-ray. The ulna isn’t the primary bone fractured in this pattern, and the tibia or fibula are leg bones, not involved in this wrist injury. So the radius is the bone involved.
