Distal radioulnar joint dislocation in association with elbow injuries

Traumatic distal radioulnar joint (DRUJ) dislocation with or without an associated fracture is a rare injury. When coupled with a radial head fracture this is commonly known as the Essex-Lopresti injury. We report two cases of elbow dislocation with ipsilateral radial neck fractures and associated true DRUJ dislocations. This has not been previously described in the literature. In elbow injuries with wrist involvement, symptoms in the latter may be subtle. Due to inadequate examination of the affected joint, poor initial radiographic views, and general rarity of this injury, distal radioulnar joint dislocations are frequently missed. We hope our experience illustrates the need to examine thoroughly the joint above and below the injured site, and to be aware of the potential for DRUJ instability in all patients with elbow injuries.
