Fracture of the proximal ulna with dislocation of radial head. Remember "M" - (m)ontegia and (m)edial side (ulna fracture) to differentiate from galeazzi which is distal radial fracture - lateral fracture. 




"Monteggia" fracture -the injury is subdivided  into 4 categories.
  • Type I Bado: Fracture of the proximal third of the ulna with anterior dislocation of the radial head.
  • Type II Bado: Fracture of the proximal third of the ulna with posterior dislocation of the radial head.
  • Type III Bado: Fracture of the ulnar metaphysis with lateral dislocation of the radial head.
