Colles' fracture

• of the distal radius and ulnar styloid

• with posterior displacement

• (of the hand)

61

Colle's fractures usually occur when an adult falls on a hyperextended, outstretched hand.

There is frequently an associated fracture of the ulnar styloid.

62

• Smith's fracture is caused by a fall on a hyperflexed, outstretched hand.

• It is sometimes referred to as a "reverse Colle's fracture."
