Answer A) Dinner fork deformity
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 are very common extra-articular fractures of the distal radius that occur as the result of a fall onto an outstretched hand.
