Answer B. Distal radius fracture (Extra Articular)
- A dinner fork deformity, also known as a bayonet deformity, occurs as the result of a malunited distal radial fracture, usually a Colles fracture.
- The distal fragment is dorsally angulated, displaced, and often also impacted.
- The term is descriptive, as the lateral view of the wrist is similar to the shape of a fork, seen from the side, tines down.
Colles fractures
- Colles fractures are very common extra-articular fractures of the distal radius that occur as the result of a fall onto an outstretched hand.
- They consist of a fracture of the distal radial metaphyseal region with dorsal angulation and impaction, but without the involvement of the articular surface.
