Nonunion of the radial head.
A case of posterior fracture-dislocation of the elbow with a comminuted radial head fracture which subsequently went on to nonunion is reported. Radiographs at followup revealed a pseudoarthrosis of the radial neck, with at least part of the normal pronation and supination occurring through the pseudoarthrosis site.
