Medial Radial Head Dislocation Associated with a Proximal Olecranon Fracture: A Bado Type V?

Table 1

Bado [1] classification of the Monteggia lesion with the proposed type V category.

Bado Type	Description
Type I (60%)	Anterior dislocation of the radial head. Fracture of the ulna with anterior angulation.
Type II (15%)	Posterior or postero-lateral dislocation of the radial head. Fracture of the ulna with posterior angulation.
Type III (20%)	Lateral or antero-lateral dislocation of the radial head. Fracture of ulna metaphysis.
Type IV (<5%)	Anterior dislocation of the radial head with fracture of the proximal third of the radius and fracture of ulna at same level.
Type V (proposed)	Medial or antero-medial dislocation of the radial head with fracture of the proximal ulna.
