Monteggia fracture
Monteggia fracture-dislocations consist of a fracture of the ulnar shaft with concomitant dislocation of the radial head.
Monteggia fracture-dislocations occur as the result of a fall onto an outstretched hand (FOOSH).
Epidemiology
Monteggia fractures occur mostly in children (peak incidence at ages 4-10 years) and rarely in adults.
