Traumatic volar dislocation of the distal radioulnar joint.
Isolated volar dislocation of the distal radioulnar joint may result from a variety of injuries. This injury is incorrectly diagnosed in approximately 50% of presented cases. A case of volar dislocation of the distal radioulnar joint by traumatic hypersupination is presented. The clinical diagnosis may be hindered by marked swelling, pain, and limitation of motion of the wrist. Dislocation can be diagnosed by accurately obtained anteroposterior and lateral roentgenograms. Closed reduction with direct pressure over the ulnar head from a volar to dorsal direction and simultaneous distraction of the wrist is the preferred method of treatment.
