A 19-year-old right-hand-dominant man sustained a right dorsal radiocarpal dislocation. He presented with instability secondary to displacement of the volar ligamentous structures and an avulsed fragment of the distal aspect of the radius within the radiocarpal articulation. The patient was treated with open reduction and internal fixation, as well as a capsuloligamentous repair. At the 18-month follow-up, he had no pain and excellent functional recovery.
Our experience emphasizes the importance of looking critically at the radiographs when there is an irreducible radiocarpal fracture-dislocation. A volar distal radial fragment and attached ligamentous structures can be the main blocks to closed reduction.
