Reconstruction of a Chronic Monteggia Fracture With Associated Radioulnar Synostosis

Patients with multiple traumatic injuries can be difficult to treat, especially when a head injury is involved. In these cases, orthopedic injuries can be missed or ignored. In patients who recover, the orthopedic injuries can be more difficult to manage at a later date. We report the case of a patient whose Monteggia fracture was unmanaged while his head injury was addressed, resulting in a malunited ulna, chronically dislocated radial head, and radioulnar synostosis.
