Location/Articulation. The ulna is one of the two bones of the forearm, parallel with the radius. It articulates with the: 1  humerus, at the elbow, as a hinge joint to allow flexion and extension. 2  radius, near the elbow as a pivot joint, to allow pronation and suppination. 3  distal radius, where it fits into the ulna notch.4  radius along its length via the interosseous membrane that forms a syndesmoses joint.t articulates with the: 1  humerus, at the elbow, as a hinge joint to allow flexion and extension. 2  radius, near the elbow as a pivot joint, to allow pronation and suppination. 3  distal radius, where it fits into the ulna notch. 4  radius along its length via the interosseous membrane that forms a syndesmoses joint.
