Colles fracture
Pronunciation: COL-eez
Distal radius fracture with dorsal angulation and displacement, typically from a fall on outstretched hand.
Full Definition
A Colles fracture is a specific type of distal radius fracture characterized by dorsal (backward) angulation and displacement of the distal fragment. Named after Abraham Colles, this injury typically occurs from a fall on an outstretched hand with the wrist in extension. The classic deformity creates a 'dinner fork' appearance on lateral radiographs. This fracture is common in elderly patients with osteoporosis and may be associated with ulnar styloid fractures. Treatment ranges from closed reduction and casting to surgical fixation depending on displacement and stability.
Usage
Usage note: Distinguish from Smith fracture which has volar (forward) angulation.
