What type of fracture is identified by a "fork appearance" of the distal radius?

A "fork appearance" of the distal radius is characteristic of a Colles fracture. This type of fracture occurs due to a fall onto an outstretched hand, resulting in a distal radius fracture where the distal fragment is displaced posteriorly. The "fork" appearance refers to the way the distal end of the radius angles upward, resembling a fork or dinner fork, which is a distinctive feature in imaging.

Colles fractures are particularly common in older adults, often related to osteoporosis, and understanding their presentation is crucial for proper diagnosis and management. Recognizing the specific angulation of the fracture helps clinicians in determining the appropriate treatment strategy, which may range from immobilization to surgical intervention depending on the severity of the fracture and any associated complications. The other types of fractures mentioned have different characteristics and mechanisms of injury that do not present with this specific "fork" appearance.
