Unusual combination of Monteggia, Colles', and navicular fractures

A rare combination of an ulnar fracture with posterior dislocation of the head of the radius and intraarticular fracture of the distal radius concomitant with an ipsilateral navicular fracture is presented. To the best of our knowledge, no such case has been reported. The mechanism of this fracture combination is discussed with respect to its role in producing the Monteggia type II fracture. Treatment consisted of a combination of closed and open reduction with external fixation.
