Distal radius fracture with associated ulnar head fracture.

Ulnar head and neck fractures are rare and the mechanism of injury is not always clear. We describe a case of a distal radioulnar joint (DRUJ) fracture dislocation. The fracture included a distal radius fracture with a vertical ulnar head fracture that was treated with open reduction and internal fixation with a headless screw. We describe the mechanism of injury and approach to the treatment of this injury.
