Monteggia-type elbow fractures in childhood.

In an analysis of 29 cases of three different Monteggia-type fractures in children, the mechanism of injury was a hyperpronation force on the extended elbow. The follow-up period ranged from one to three years with a mean of 18 months. Closed reduction of these fractures was always difficult to maintain because the lesions are unstable. Closed reduction was successful in 25 of the 29 cases and open reduction was required in four. A slight residual dorsal angulation remained in 18 cases with fracture of both bones of the forearm, but healing in this position was acceptable.
