Monteggia's fracture is a fracture of the forearm. It is caused by a fall on the forearm under bending of the ellbow. In Monteggia's fracture, the proximal ulna is broken in particular. At the same time, the head of the radius is luxated ventrally and laterally, this is, in direction of the body.
Normally, the ulnar fracture is operatively stabilized with metal plates; the radial ligaments possibly must be sutured. Immubilization by plaster follows after surgical therapy.
