distal radioulnar articulation

(redirected from Distal radio-ulnar joint)

dis·tal ra·di·o·ul·nar joint

the pivot synovial joint between the head of the ulna and the ulnar notch on the radius; an articular disc passes across the distal part of the joint.

distal radioulnar articulation

the pivotlike articulation of the head of the ulna and the ulnar notch on the lower end of the radius, involving two ligaments. The joint allows rotation of the distal end of the radius around an axis that passes through the center of the head of the ulna. Also called inferior radioulnar joint. Compare proximal radioulnar articulation.
