Colles fracture is commonly associated with injury to which bone region?

Explanation:
Colles fracture is defined by a fracture of the distal radius near the wrist with dorsal (posterior) displacement after a fall on an outstretched hand. The force travels to the end of the radius at the wrist, so the injury occurs in the distal radius, not the proximal radius or ulna, and not the distal ulna. The classic dinner fork appearance comes from that dorsal tilt of the distal fragment. While an ulnar styloid fracture can accompany it, the primary location of the fracture is the distal radius.
