Eighty percent of axial load is supported by the distal radius and twenty percent by the ulna. Distal radioulnar joint (DRUJ) arthritis is an inflammatory condition characterized by gradual wearing away of the cartilaginous surface of the radioulnar joint resulting in significant pain, swelling, stiffness, and interference in the functioning of the wrist and/or arm. Uniform results and consistent pain relief do not follow. Distal radioulnar joint: is a joint in the upper limb, especially in the forearm proximal to the wrist joint lying between the distal heads of radius and ulna bones. The articular surfaces are connected together by the following ligaments: The distal radioulnar joint is the articulation between the crescent-shaped convex distal head of ulna and the concave ulnar notch of radius. If more than 50% of the articular surfaces do not articulate, then the term DRUJ subluxation is used 3. For the movements against resistance and/or when the forearm is flexed, the biceps brachii muscle acts as an accessory supinator.

Grounded on academic literature and research, validated by experts, and trusted by more than 2 million users. In simple words, these are the rotatory movements by which the forearm and hand rotate around the long axis of the forearm. The intrinsic stabilizers are the joint capsule, triangular fibrocartilage complex (TFCC) and distal radioulnar ligaments. Muscles that contribute to function are all supinator (biceps brachii, brachioradialis, and supinator) and pronator muscles (brachioradialis, pronator quadratus, and pronator peres). Postoperatively, immobilize the [4] Supination (palms facing up) vs. pronation (palms facing down). If more than 50% of the articular surfaces do not articulate, then the term DRUJ subluxation is used 3. Mikic ZDJ. followed by rehabilitation to gradually restore forearm rotation. The distal radioulnar articulation (inferior radioulnar joint) is a synovial pivot-type joint between the two bones in the forearm, the radius and ulna. interosseous membrane is disrupted and the palmar radioulnar ligament Weiler PJ, Bogoch ER. The function of the radioulnar joint is to lift and maneuver weight load from the distal radioulnar joint to be distributed across the forearms radius and ulna as a load-bearing joint. This is best accomplished with the patients elbow resting on the The clinical examination must identify all damaged structures in order to define a customized reconstruction strategy.

This is a uniaxial pivot joint that allows the movements in one degree of freedom; pronation-supination. Mikkelsen SS, Lindblad BE, Sommer J. Sauv-Kapandji Operation for Disorders of the Distal Radioulnar Joint. The former two cross the joint and hold it tight, while the latter holds the facing surfaces of the shafts of the radius and ulna firmly connected. Left unchecked, this dynamic tensioning ultimately would lead to The distal radioulnar joint is a uniaxial joint that has one degree of freedom; During these movements, the distal end of radius rotates around the head of ulna. The dorsal and palmar parts of the TFCC are thickened and known as the dorsal and palmar radioulnar ligaments, respectively. Three critical questions should be addressed and answered before any supination. Bieber EJ, Linscheid RL, Dobyns JH, Beckenbaugh RD. The articular surfaces are connected together by the following ligaments: Articular disc Excision of the Distal End of the Ulna in Rheumatoid Arthritis. The posterior interosseous and ulnar arteries contribute to the joint vascularization to a smaller extent. relative lengths of the ulna and radius, and most patients are more Close the soft tissues in routine fashion.
