The distal radioulnar joint is formed by the articular circumference of the radius and the radial notch of the ulna. It is considered as a proximal continuation of the antebrachiocarpal joint in carnivores and pigs. It is not present in ungulates.

The distal radioulnar joint is composed by an articular capsule that is continuous with the interosseous membrane of forearm, and the radioulnar ligament that extends between the radial trochlea and the styloid process of ulna.

It is a distinct ligament in dogs, whereas in cats it consists of fibres embedded in the joint capsule.
