What is the name of the fracture involving the distal radius with volar displacement, commonly occurring from a fall on the back of the hand?

The fracture that involves the distal radius with volar displacement and commonly occurs from a fall on the back of the hand is known as a Smith fracture. This type of fracture is characterized by when the wrist is flexed and weight is applied, which shifts the distal fragment of the radius ventrally (downward).

Smith fractures typically result from a direct impact or a fall on an outstretched hand (FOOSH injury), particularly when the wrist is in a flexed position. This makes them less common than other types of wrist fractures, such as Colles fractures, which have dorsal (posterior) displacement. Understanding how these fractures occur helps differentiate them based on the mechanism of injury and the position of the wrist at the time of impact.

Recognizing the specific characteristics of a Smith fracture is crucial for proper diagnosis and treatment, ensuring that appropriate management strategies are employed to facilitate optimal recovery and function post-injury.
