[Monteggia-fractures and Monteggia-like Lesions]

Monteggia lesions and Monteggia-like lesions involve ulna and radius injuries, which can not be successfully treated using the surgical principles of isolated fractures. Proximal ulnar fracture, radio-humeral dislocation, and additional dislocation in the proximal radioulnar joint result in the disintegration of the functional unit, and there is a complex injury across the elbow to the forearm, resulting in poor clinical outcomes. Thus, addressing all osteo-ligamentous injuries is essential for the long-term course.
