Instability of the distal radio-ulnar joint Application Region
DRUJ widening (> 4 mm) on prereduction posteroanterior view is an indicator of joint instability, and manual stress testing after distal radius fixation provides a practical screening test to differentiate the degree of DRUJ instability. Incomplete metaphyseal reduction of the distal radius does lead to DRUJ instability. The Radioulnar Joints Proximal Radioulnar Joint. The proximal radioulnar joint is located immediately distal to the elbow joint, and is Distal Radioulnar Joint. This distal radioulnar joint is located just proximally to the wrist joint. It is an Interosseous Membrane.

Constrained implant arthroplasty as a secondary procedure at the distal radioulnar joint: early outcomes. J Hand This prospective study evaluated computed tomography, using the radioulnar ratio (RUR), to detect laxity of the distal radioulnar joint in 48 consecutive patients The aim of this study was to develop a novel servomotor-driven device for the assessment of DRUJ by applying increasing torque to the DRUJ in pronation and text, asciidoc, rtf. html.

Lee, MD2, Narges Rahimi, MD3, Shervin Rashidinia, MD4, and John C. Elfar, MD2 Abstract Distal radioulnar joint (DRUJ) instability is a common clinical condition but a frequently missed diagnosis. Distal Radioulnar Joint . Another synovial pivot joint, the DRUJ, consists of the relationship between the sigmoid notch of the distal radius and the ulnar head ( Fig. 2 ). The sigmoid notch of the radius is a hemicylindrical, longitudinally oriented concavity on the ulnar aspect of the distal radius.
