2) Caused by receiving a blow when protecting onself, dislocation of radial head and fracture of the ulna.
3) Caused by falling on outstretched hand and dislocating the distal radio-ulnar joint and fracturing the distal radius.
1) Radial Head fracture
2) Monteggia Fracture-dislocation (night-stick)
3) Galeazzi Fracture-dislocationElbow
Mnemnonic:
Policeman Radii Galeazzi tried to hit thief Ulna Monteggia for stealing his bike. Ulna Monteggia blocked the blow to his forarm and tripped Policeman Radii Galezzi who fell on his outstretched hand.
