Abstract

There are variable types in wrist joint injury. Most common case is simple distal radius fracture. And ulnar head dislocation associated with disruption of distal radioulnar ligament is unusual. Among thease injury types. volar dislocation of ulnar head in the distal radioulnar joint is not common and it is misdiagnosis frequently. So it needs to surgical operation frequently. The author reviews this injury with the relevant literature.
