Monteggia fracture-dislocations consist of a fracture of the ulnar shaft with concomitant dislocation of the radial head. The ulnar fracture is usually obvious. Monteggia appreciated that the ulna fracture was linked to the radial head the term Monteggia fracture-dislocation in in his publication Thesis de Paris. Monteggia described a fracture of the proximal third of the ulna with . Reynders P, De Groote W, Rondia J, Govaerts K, Stoffelen D, Broos PL.

Fracture of the proximal or middle third of the ulna with anterior dislocation of the radial head most common in children and young adults.
Fracture of the ulnar metaphysis distal to coronoid process with lateral dislocation of the radial head. Fracture of the proximal or middle third of the ulna and radius with dislocation of the radial head in any direction.
Fracture extending to distal half of ulna. Radiographs recommended view AP and Lateral of elbow, wrist, and forearm CT scan helpful fd fractures involving coronoid, olecranon, and radial head.
