Anatomical terminology

The distal radioulnar articulation (inferior radioulnar joint) is a joint between the two bones in the forearm; the radius and ulna. It is one of two joints between the radius and ulna, the other being the proximal radioulnar articulation. The distal radioulnar articulation is the one of the two closest to the wrist and hand.

The distal radioulnar articulation pivot-joint formed between the head of ulna and the ulnar notch on the lower extremity of radius.

Ligaments

The articular surfaces are connected together by the following ligaments:

• Palmar radioulnar ligament
• Dorsal radioulnar ligament
• Articular disk (triangular fibrocartilage)

Function

The function of the radioulnar joint is to lift and maneuver weight load from the distal radioulnar joint to be distributed across the forearm’s radius and ulna as a load-bearing joint. Supination of the radioulnar joint can move from 0 degrees neutral to approximately 80-90 degrees where Pronation of the Radioulnar Joint can move from 0 degrees neutral to approximately 70-90 degrees. Supination (palms facing up) vs. pronation (palms facing down). Muscles that contribute to function are all supinator (Biceps Brachii, Brachioradialis, and Supinator) and pronator muscles (Brachioradialis, Pronator Quadratus, and Pronator Teres).

Injuries

Injuries to the distal radioulnar articulation often result from falls onto an outstretched hand. Injury can occur with concurrent fracture of the distal radius, the ulna, or can be isolated. A classification system has been proposed by Estaminet and colleagues.

Estaminet Classification

Estaminet classified injuries of the distal radioulnar articulation into four categories with two sublcasses: purely ligamentous (subclass A) and those with associated boney injury (subclass B).

• Estaminet I - Attenuation on MRI only
• Estaminet II - Volar distal radioulnar ligament is involved. Unstable in supination. Fixation should be in pronation.
• Estaminet III - Dorsal distal radioulnar ligament is involved. Unstable in pronation. Fixation should be in supination.
• Estaminet IV - Both ligaments are involved. Unstable in both supination and pronation. Fixation is in neutral.
