Which wrist fracture is most commonly associated with a fall on an outstretched hand (FOOSH)?

The Colles fracture is the most commonly associated wrist fracture resulting from a fall on an outstretched hand (FOOSH). This type of fracture typically occurs in the distal radius and is characterized by the dorsal angulation and often dorsal displacement of the fracture fragment. It commonly happens when a person attempts to break a fall by extending their wrist, which places significant stress on the distal radius.

This mechanism of injury is prevalent among various populations, particularly the elderly, who may have weaker bones and are more prone to falls. The characteristic presentation and the common occurrence in typical fall scenarios make the Colles fracture a classic teaching point in orthopedic education.

Other types of fractures, although they may occur in similar circumstances, do not have the same prevalence related to FOOSH injuries. Smith's fractures, for instance, occur due to a fall on a flexed wrist and involve a different mechanism. Bennett's fractures involve the base of the first metacarpal and are more associated with specific injuries to the thumb rather than generalized falls. Scaphoid fractures, while they can occur from a FOOSH injury, are less common compared to the incidence of Colles fractures and typically present a different clinical picture.
