Monteggia Fracture - Symptoms and Treatment
A Monteggia fracture is a variant of an ulna fracture of the forearm. In addition to the fracture of the ulna, these patients also have a dislocation of the radial head within the elbow joint.
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.
