Monteggia equivalent fracture associated with Salter I fracture of the radial head.

Monteggia fracture is an infrequent lesion, which associates ulna fracture and radial head dislocation. Equivalent Monteggia can occur by associated lesions such as olecranon fracture or radial neck or head fracture. We report an unusual case of Monteggia equivalent lesion associating a fracture of the proximal third of the ulnar shaft and a growth plate fracture Salter I of proximal-radial physis and divergent displacement due to a bottle-opener effect of the radial head over the capitellum during trauma. Surgical care consisted of intramedullary pinning of the radial head and fixation by a plate for ulna with a very good outcome.
