Question: 1 / 400

Which term is used for a fracture in which the distal radius and ulna are displaced in a volar direction?

Thomas

Smith

The term used for a fracture in which the distal radius and ulna are displaced in a volar direction is known as a Smith fracture. This type of fracture specifically occurs when the distal fragment of the radius is displaced anteriorly or volarly, which is characteristic of the injury.

It is essential to differentiate this from other types of fractures. For example, a Colles fracture, which is often confused with a Smith fracture, involves dorsal (posterior) angulation and is the result of a fall on an outstretched hand. In contrast, a Smith fracture typically occurs from a fall onto a flexed wrist or from direct trauma that causes the wrist to bend forward.

Understanding this distinction helps in diagnosing the injury accurately and determining the appropriate treatment. The term Smith fracture honors the surgeon who first described it, further solidifying its recognition in the medical field.
