Radioulnar synostosis following proximal radial fracture in child.

A case is presented with an eight-year follow-up of a proximal radial fracture complicated by radioulnar synostosis. The case and a review of the literature reveal that the complication is associated with certain risk factors. These factors include a fracture in a child over ten years of age with a severe degree of angulation, displacement uncorrected over 4 mm, concomitant posterior dislocation of the elbow, treatment by open reductions supplemented with transcapitellar wires, and a fracture treated by late open reduction without osteotomy.
