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. It is one of two joints between the radius and ulna, the other being the proximal radioulnar articulation.
To cover the ulna head by extending the articular surface of the distal radius. Load transmission across the ulnocarpal joint and partially load absorbing; Allows forearm rotation by giving a strong but flexible connection between the distal radius and ulna. It also supports the ulnar portion of the carpus.
The major exception is when the joint between these bones, the distal radioulnar joint (or DRUJ), is unstable. When the DRUJ is unstable, the ulnar styloid may require independent treatment. An excessively long styloid process of the ulna can cause painful contact with the triquetral bone in the wrist, known as ulnar styloid impaction syndrome. [1]
The ulna is approached from the subcutaneous border. A plate is attached to the distal end of the ulna, to plan the osteotomy. An oblique segment is removed from the ulna, after which the distal radial-ulnar joint is freed, making sure structures stay attached to the styloid process. After this, the freed distal end is reattached to the ...
The distal radioulnar joint (DRUJ) is a pivot joint located between the distal ends of the radius and ulna, which make up the forearm. Formed by the head of the ulna and the ulnar notch of the radius, the DRUJ is separated from the radiocarpal (wrist) joint by an articular disk lying between the radius and the styloid process of the ulna.
The articular surface for the ulna is called the ulnar notch (sigmoid cavity) of the radius; it is in the distal radius, and is narrow, concave, smooth, and articulates with the head of the ulna forming the distal radioulnar joint.
The Galeazzi fracture is a fracture of the distal third of the radius with dislocation of the distal radioulnar joint.It classically involves an isolated fracture of the junction of the distal third and middle third of the radius with associated subluxation or dislocation of the distal radio-ulnar joint; the injury disrupts the forearm axis joint.
The joints in the hand are joints found at the distal end of the upper limb.. The joints are: In the wrist there is the radiocarpal joint between the radius and carpus.Between the carpal bones are the intercarpal articulations and the midcarpal joint.
