Monteggia Fracture

General Considerations

  • Relatively uncommon fracture of the ulna with dislocation of the radial head
    • Galeazzi fractures are three times more common
  • Radial head dislocation may be subtle
  • Most are as Monteggia first described them (1814) which are fractures of proximal third of ulna with anterior dislocation of radial head
  • Bado type 1 is most common: Fracture of the proximal or middle third of the ulna with anterior dislocation of the radial head
