Fracture of the distal
Radius Bone . For more detailed discussion see
Distal Radius Fracture .
It is named after
Abraham Colles (1773-1843), an
Irish Surgeon who first described this in 1814.
The fracture is most commonly caused by people falling forward onto a hard surface and breaking their fall with extended, outstretched hands - falling with
Wrist s flexed would lead to a
Smith's Fracture . It usually occurs about an inch or two proximal to the
Radio-carpal Joint with posterior and lateral displacement of the distal fragment resulting in the characteristic
Dinner Fork like deformity.
Treatment of depends on the severity of the fracture. An undisplaced fracture may be treated with a cast alone. A fracture with mild angulation and displacement may require closed
Reduction . Significant angulation and deformity may require an open reduction and
Internal Fixation or external fixation.
