The lateral projection demonstrates dorsal subluxation of the distal ulna at the distal radioulnar joint (DRUJ). The elbow joint is normally aligned although there is a subtle mildly impacted fracture of the radial neck. No ulnar fracture is evident. This pattern of injury is consistent with Essex-Lopresti fracture-dislocation.
Case Discussion
The Essex-Lopresti fracture-dislocation is a fracture of the radial head or neck with transmission of the force along the interosseous membrane to disrupt the DRUJ.
