A fracture of the distal radius characterized by anterior displacement of fragments is termed what?

• A. Colles fracture
• B. Smith fracture
• C. Boxer fracture
• D. Greenstick fracture

Answer: (B)

The fracture of the distal radius characterized by anterior displacement of fragments is known as a Smith fracture. This type of fracture typically occurs when there is a fall onto a flexed wrist or as a result of trauma that causes the wrist to bend forwards, leading to the anterior displacement of the broken bone fragments.

In contrast to other types of fractures listed, the Smith fracture specifically involves the distal radius with the dorsal (posterior) side of the wrist being affected. The Colles fracture, for example, is known for its posterior displacement of the distal radius fragments, which is the opposite of what occurs in a Smith fracture. Boxer fractures generally refer to fractures of the fifth metacarpal, usually due to punching an object, while greenstick fractures are incomplete fractures often seen in children, characterized by bending or splintering rather than an anterior or posterior displacement. Understanding the precise patterns of bone displacement is crucial for accurate diagnosis and treatment in radiography and orthopedics.
