Colles' fracture
Pronunciation: CALL-eez
Common wrist fracture involving the distal radius with characteristic dorsal angulation and displacement.
Full Definition
Colles' fracture is a specific type of distal radius fracture first described by Abraham Colles in 1814. The fracture typically occurs within 2-3 cm of the radiocarpal joint and is characterized by dorsal angulation, radial shortening, and often dorsal displacement of the distal fragment. This injury commonly results from a fall on an outstretched hand (FOOSH injury) and is particularly prevalent in elderly patients with osteoporosis. The classic "dinner fork" deformity is visible on clinical examination due to the dorsal displacement of the hand relative to the forearm.
Usage
Usage note: Always include apostrophe in Colles'; avoid using 'Colles fracture' without the possessive.
