Monteggia vs Galeazzi


  • A Monteggia fracture is a fracture of the proximal ulna with dislocation of the radial head.
  • There are four types, based on the direction that the radial head is displaced (Bado classification).
  • A Galeazzi fracture is a fracture of the distal radius with dislocation of the distal radioulnar joint (DRUJ).

Fracture-dislocation Mnemonic

  • MUGR (pronounced “MUGGER”): identifies the fractured bone.
  • MU: Monteggia Ulna
  • GR: Galeazzi Radius
  • Use “A to Z” to remember the location of the fracture-dislocation.
  • ‘A’ is proximal (MonteggiA)
  • Radial head dislocation and proximal ulna fracture
  • ‘Z’ is distal (GaleazZi)
  • Distal radioulnar joint dislocation and distal radius fracture
