The effect of dorsally angulated distal radius fractures on distal radioulnar joint congruency and forearm rotation.
Peripheral tear of the triangular fibrocartilage: Depiction with MR arthrography of the distal radioulnar joint.
The long axis (transverse diameter) and the short axis (anteroposterior diameter) of the median nerve, were evaluated on axial (transverse) plan evaluated on milimetric measurement of proximal (distal radioulnar joint level, RU), medium (pisiform bone level, P) and distal (level of the hamate hook, H) parts of the carpal tunnel and the flattening ratio was established for each plane (by dividing long axis with short axis).
There is fluid surrounding the radial head just distal to the proximal radioulnar joint.
Osteoarthritis in the distal radioulnar joint of the wrist
Cadaveric sections have shown that there is a 50% reduction in the proximal radioulnar joint space when moving from full supination to full pronation.
The predominant radiologic findings include triangularization of the distal radial epiphysis with shortening of the ulnar segment, dorsal dislocation of the distal ulna that cannot be easily reduced, pyramidalization of the distal carpal row, shortening and bowing of the distal radius, and widening of the distal radioulnar joint.
46) A shortened radius increases the strain on the TFCC, which may result in distal radioulnar joint (DRUJ) instability.
