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. CT Findings in Distal Radioulnar Dislocation. Kihara H, Short WH, Werner FW, et al. The distal radioulnar joint formed from the articulation between the distal head of ulna (crescent and convex shaped) and the ulnar notch of radius (concave shaped), (the ulnar head sits within the sigmoid notch of the radius . The radioulnar articulation is formed by the lower end of ulna (seat) and the sigmoid notch (medial articular facet) of the distal radius [Figure 1].The sigmoid notch of the radius is concave with a radius of curvature of approximately 15 mm 4. Most important, the DRUJ acts in concert with the proximal radioulnar joint to allow the wrist and hand to rotate from pronation to supination and back again. studied 120 fetal and infant wrists and found perforations in 27 (23%). are 43.5). or chronic)? Palmer and Werner found that The distal radioulnar joint is a synovial joint between the distal ends of the radius and ulna. suggests treatment strategies for specific conditions. Transverse section across distal ends of radius and ulna. Dislocation of the distal radioulnar joint (DRUJ) is an extremely rare injury, particularly when it occurs without associated fractures of the distal radius and ulna. It is the palmar radioulnar Register now Kim Bengochea, Regis University, Denver. An End Result Study of Twenty-four Cases.

I prefer that patients keep their wrists in neutral for this important to do this while holding the forearm in neutral rotation. Ulnar head deformation, high Larsen grades, and large dorsal protrusion are potential risk factors for extensor digitorum communis rupture. Impingement Lesions Treatment Algorithm, Table 43.5. In simple words, these are the rotatory movements by which the forearm and hand rotate around the long axis of the forearm. The articular surfaces are connected together by the following ligaments: If more than 50% of the articular surfaces do not articulate, then the term DRUJ subluxation is used 3. Palmer AK, Werner FW.

They're customizable and designed to help you study and learn more effectively. DRUJ Pathology General Treatment Algorithm, Table 43.4. Edinburgh: Elsevier Churchill Livingstone. 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. The posterior interosseous and ulnar arteries contribute to the joint vascularization to a smaller extent. [2] The articular disc acts to firmly bind the distal extremities of the two bones together. Isolated Traumatic Dislocation of the Distal End of the Ulna or Distal Radioulnar Joint.
