A Monteggia fracture is a fracture of the proximal ulna with radial head dislocation. The Bado classification is frequently used, though it does not cover all patterns. Type 1 is the most common, while Types 3 and 4 are rare. A rare complication is radial nerve palsy, particularly posterior interosseous nerve palsy, which usually manifests as neuropraxia and resolves spontaneously.
