In a Colles fracture, what type of angulation is typically seen?

A Colles fracture is a specific type of distal radius fracture that usually occurs from a fall onto an outstretched hand. The hallmark feature of a Colles fracture is the dorsal angulation of the distal fragment. This angulation means that the fractured end of the radius tilts or points towards the dorsal side (the back of the hand), resulting in a characteristic "dinner fork" or "bayonet" appearance of the wrist.

Understanding that the fracture typically occurs when a person falls and extends their arm forward, the natural response is to brace oneself with the palm down, which results in this specific angulation pattern if a fracture occurs. Dorsal angulation is one of the primary diagnostic findings in these cases, and recognizing this feature is essential for proper diagnosis and treatment of the fracture.
