Smith fracture

Smith Fracture

A Smith fracture (pronounced: /smɪθ ˈfræk.tʃər/), also known as a reverse Colles' fracture, is a specific type of fracture of the distal radius.

Etymology

The term "Smith fracture" is named after the Irish surgeon, Dr. Robert William Smith, who first described this type of fracture in 1847.

Definition

A Smith fracture is characterized by a transverse fracture of the distal radius with volar (or anterior) displacement and angulation of the distal fracture fragment. This is in contrast to a Colles' fracture, which involves dorsal (or posterior) displacement of the distal fracture fragment.

Causes

Smith fractures are typically caused by a direct blow to the dorsal surface (back) of the wrist, such as a fall onto an outstretched hand with the wrist flexed, or a direct blow from an object.

Symptoms

Common symptoms of a Smith fracture include pain, swelling, and deformity at the wrist, particularly on the volar (palm) side. There may also be difficulty moving the wrist and hand.

Diagnosis

Diagnosis of a Smith fracture is typically made through physical examination and confirmed with X-ray imaging.

Treatment

Treatment of a Smith fracture may involve immobilization with a cast or splint, or surgical intervention, depending on the severity and exact nature of the fracture.
