Proximal radioulnar joint
From Wikipedia, the free encyclopedia
(Redirected from Proximal Radioulnar Joint)
An articulation between the radial head and the radial notch of the ulna. The radial head spins in the radial notch of the ulna and is supported by the anular ligament. Along with the distal radioulnar joint these two joints act as pivot joints for axial rotation of the antebrachium (pronation and supination).
