Fracture of the Radial Neck and Proximal Ulna with Medial Displacement of the Radial Shaft

Abstract

The classification of proximal radial fractures into three major groups, according to Chambers, is based on the mechanism of injury and the displacement of the radial head. In the head-displaced fractures (group I) the radial head is primarily displaced. The two subclasses of fractures in group I are angular injuries and those associated with elbow dislocations. In the neck-displaced fractures (group II) the distal radial fragment is primarily displaced. Finally, stress injuries are included in group III. A child with a fracture of the radial neck and proximal ulna with complete medial displacement of the radial shaft is presented and the classification of the injury is discussed.
