Mar 30, 2025 · The radioulnar joints are two locations in which the radius and ulna articulate in the forearm: Proximal radioulnar joint – located near the elbow. It is articulation between the head of the radius and the radial notch of the ulna. Distal radioulnar joint – located near the wrist.

Nov 3, 2023 · The proximal radioulnar joint is a synovial joint that connects the proximal ends of the radius and ulna. In this joint, the circumferent head of radius is placed within the ring formed by the radial notch of ulna and the annular ligament.

The distal radioulnar articulation [1] (also known as the distal radioulnar joint, [2] or inferior radioulnar joint [1] [3]) is a synovial pivot joint between the two bones in the forearm; the radius and ulna.

Oct 30, 2023 · The radius and ulna are long bones that make up the forearm, extending from the elbow to the wrist. In the anatomical position, the radius is found in the lateral forearm, while the ulna is found in the medial forearm.

Aug 25, 2018 · Ulna (plural: ulnae; pronunciation: úl-nu) is one of the two primary bones forming the forearms in humans, the other one being the radius. There is one ulna bone in each arm. It is a long bone [1] and is vital in forming both the wrist and elbow joints [2].

Feb 3, 2025 · The proximal radioulnar articulation, sometimes referred to as the proximal radioulnar joint (PRUJ), is a synovial pivot joint that occurs between the ring created by the annular ligament and the radial notch of the ulna and the circumference of the radius head.

Nov 18, 2022 · The distal radioulnar joint (DRUJ) is the distal articulation between the radius and ulna, acting as a major weight-bearing joint at the wrist and distributing forces across the forearm bones.

Nov 3, 2023 · The distal radioulnar joint is the articulation between the crescent-shaped convex distal head of ulna and the concave ulnar notch of radius. Both surfaces are lined by the hyaline cartilage. The joint contains a triangular fibrocartilaginous articular disc.

The radioulnar joints are two joints between the two bones of the forearm: the ulna, on the medial side, and the radius, on the lateral side. There’s one superior, or proximal radioulnar joint, and one inferior, or distal radioulnar joint, and together they allow …

Aug 8, 2018 · Radio-Ulnar Joint is a pivot type of synovial joint. The articulating surfaces are: (a) circumference of radial head and (b) fibro-osseous ring made by radial notch of ulna and annular ligament. Capsular ligament (joint capsule): The fibrous capsule surrounds the radio-ulnar joint.
