Irreducible distal radioulnar joint occurring in a Galeazzi fracture - case report.

This is a report of an irreducible distal radioulnar joint associated with a Galeazzi fracture. The irreducible dislocation of the radioulnar joint was not appreciated until 2 weeks following compression plating of the radius fracture. The extensor carpi ulnaris was found to be wrapped anteriorly about the ulnar border of the distal ulna and was trapped in this position by the displaced ulnar styloid. The patient was successfully treated with open reduction of the styloid fracture and temporary wire fixation.
