Abstract
The distal radioulnar joint has a unique architecture that simultaneously allows a wide arc of forearm rotation but requires the coordination of a primary ulnoradial ligament and secondary supporting structures to maintain stability Clinically, the majority of dislocations involving the DRUJ are dorsal, where the distal ulna is dorsal to the distal radius. It has been felt that the combination of forearm pronation and wrist hyperextension predisposes to this injury pattern. Conversely, palmar dislocations, in which the distal ulna is anterior to the distal radius, are thought to occur in a supinated forearm. The potential importance of dynamic stabilization of the DRUJ by the extensor carpi ulnaris and the pronator quadratus, especially the deep head, have been advanced and even recognized in some innovative surgical reconstruction procedures.
