1) Fractures of the distal radius and ulna:

  • These fractures account for 75% of all radius and ulna shaft fractures:

2) Fractures of the middle third:

  • These fractures account for 18% of both bone fractures:

3) Monteggia and Galeazzi fracture dislocations:

  • The MONTEGGIA FRACTURE is a combination of an ulnar fracture and a radial head dislocation
    • in Figure 5 there is a mid- shaft ulnar fracture
    • In a normal forearm, the radial head should point at the capitellum in all views and a line drawn down the long axis of the radius should intersect the capitellum
    • in both views, Figure 5 and Figure 6, the line drawn down the long axis of the radius does not intersect which indicates that the radial head is dislocated
  • The GALEAZZI FRACTURE is a radial shaft fracture, generally at the junction of the middle and distal thirds, which is accompanied by disruption of the distal radioulnar joint
    • In Figure 7 and 8 there is a fracture of the radius associated with a dislocation of the distal ulna
