These are combined injuries of the forearm in elbow and were first described by Giovanni Monteggia in the 1800s. Children are by far the most common group affected, typically with a fall on an outstretched hand. The ulna (a forearm bone) is broken or deformed (excessively bowed) and the radial head is dislocated (elbow).
Timely recognition of these injuries is important and often requires operative intervention, even when recognized immediately. This may mean placing some metal hardware to maintain the forearm and elbow in a correct position for healing.
