The fracture shown in the photograph above represents Monteggia fracture.
Monteggia fracture-dislocations are classified by the Bado system
- Bado type I injuries are characterized by a proximal ulnar fracture with anterior dislocation of the radial head. This is due to a forceful pronation injury of the forearm and is the most common type.
- Bado type II injuries are “reversed” Monteggia fracture-dislocation injuries.
- Here, there is posterior angulation of the ulnar fracture site and posterior dislocation of the radial head. Bado type III and IV are rare injuries.
