[Radial head anterior dislocation and ulna bowing in children: About 3 cases and review of the literature].

We present three cases of anterior dislocation of the radial head associated with plastic deformation of the ulna in children. It is a Monteggia equivalent lesion type 1 according to the Bado's classification. Radiological diagnosis often goes unnoticed to the untrained eye. The relationship between the radius and the capitulum identifies the dislocated radial head on radiographs AP or lateral. Line Mubarak highlights the bowing of the ulna on radiographs lateral. Evolution is pejorative in the absence of early orthopedic care. Older is the patient and longer is the time between injury and treatment, less good are the clinical and radiological results. The first line treatment is closed reduction of the dislocation of the radial head and the bowing of the ulna. Surgical treatment is indicated in cases of failure of closed reduction. Adequate surgical treatment is that which allows and maintain the reduction. The surgery is the most possible minimally invasive. Open reduction can be associated with various surgical techniques: the annular ligament plasty, the establishment of a transitory pin intra-articular capitulo radiale, the ulna osteotomy, the radial osteotomy. Radial head resection is not indicated in children.
