What is a characteristic feature of a Colles fracture?

A characteristic feature of a Colles fracture is that it typically presents as a dorsally displaced fracture. This type of fracture occurs at the distal radius, usually resulting from a fall onto an outstretched hand, which causes the distal fragment of the radius to be displaced posteriorly. The hallmark of a Colles fracture is the "dinner fork" deformity, where the wrist appears bent upwards.

This dorsally displaced aspect is crucial in understanding the mechanism of injury and the resultant deformity associated with Colles fractures. Recognizing this pattern can assist in diagnosis and management, including appropriate immobilization and planning for potential surgical intervention if needed.

Additionally, while it is important to understand that Colles fractures may have intra-articular or extra-articular components, the defining feature remains the dorsal angulation and displacement of the fracture fragment. The other options involve types of displacement or fracture characteristics that do not accurately represent the defining features of a Colles fracture.
