What is the most likely finding? The Bado classification of Monteggia fracture types is based on the recognition that the direction in which the apex of the ulnar fracture points is the same direction as the radial head dislocation 4). In addition, there are substantial differences between Monteggia injuries in children and adults. Monteggia, Galeazzi, and Essex-Lopresti injuries are the most common types of fracture–dislocation of the forearm. The radial head may be palpable in the dislocated position and the angulation of the ulna shaft may be visualized or palpable.

Earlier studies have reported on the results of treating Monteggia fractures in children and adults even though this type of fracture is different in these two patient populations.
