What refers to the distal fragment positioning in a Colles fracture?

In a Colles fracture, the distal fragment of the radius is typically displaced dorsally. This type of fracture most commonly occurs as a result of a fall onto an outstretched hand, leading to a fracture just above the wrist. When the fracture occurs, the distal fragment tilts posteriorly relative to the proximal portion of the radius. This dorsally displaced positioning is a key characteristic of a Colles fracture and is crucial for accurately diagnosing and managing the injury. Understanding this displacement pattern can assist healthcare professionals in providing appropriate treatment and anticipating potential complications associated with the fracture.
