Colles’ FractureExtension-Compression Fracture of Distal Radius

FX WITH

POSTERIOR

DISPLACEMENT

Colles' fracture• of the distal radius

and ulnar styloid• with posterior

displacement

• (of the hand)

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

• There is frequently an associated fracture of the ulnar styloid.

• Although Colle's fractures are not intra-articular fractures, secondary degenerative arthritis may develop at the wrist joint.

Smith's fracture• of the distal radius

and ulnar styloid• with anterior

displacement.

SMITH’S FXFlexion-Compression

FX WITH

ANTERIOR

DISPLACEMENT

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

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