[Monteggia injury in childhood: a frequent cause of chronic dislocation of the head of the radius].

Two cases of chronic dislocation of the radial head after Monteggia lesions in children are described. The late reconstruction with open reduction of the radial head combined with osteotomy of the ulna is mentioned as the therapy of choice before skeletal maturity, because the pathophysiology of the lesion is best considered. The operative procedure in detail is given. Finally, alternative procedures are presented and discussed.
