What type of fracture occurs at the wrist due to falling on an outstretched hand?

A Colles' fracture is characterized by a specific pattern that occurs at the distal radius, typically as a result of falling on an outstretched hand. When someone falls and extends their arm to break the fall, the force transmitted through the wrist can cause the distal radius to break. This type of fracture commonly results in dorsal angulation and often occurs in the elderly due to weakened bone density.

Colles' fractures are particularly significant because of their commonality and the potential complications that can arise, such as impaired wrist function, chronic pain, and the possibility of affecting the patient's ability to perform daily activities.

While radial and ulnar fractures may also occur in similar circumstances, a Colles' fracture specifically refers to the break in the radius with the characteristic dorsal displacement. Furthermore, a Smith's fracture, which is another wrist fracture, occurs with a similar mechanism but typically involves palmar angulation instead of dorsal angulation. Understanding these distinctions is crucial for accurate diagnosis and treatment of wrist injuries following falls.
