What is the mechanism of this fracture and who is typically affected?
Most Colles fractures are secondary to a fall on an outstretched hand (FOOSH) with a pronated forearm in dorsiflexion. Although Colles fractures are seen in all age groups and demographics, they particularly common in osteoporotic individuals and as such are most frequently seen in elderly women.
Transverse fracture through the distal radius is demonstrated associated with approximately 20 degrees of dorsal angulation. No articular involvement. No ulnar styloid fracture.
