Arthroscopic Reduction and PercutaneousPinning of a Radiocarpal Dislocation

R adiocarpal dislocations are complex injuries characterized by high-energy shear and rotational forces to the wrist, often combined with a fracture of the distal part of the radius or ulna. They often present as open fractures and can be complicated by soft-tissue injuries such as intercarpal and radiocarpal ligament tears and nerve injuries. Current management of radiocarpal dislocations is based on treatment principles described by Ilyas and Mudgal, which include concentric reduction of the radiocarpal joint, identification and appropriate treatment of intercarpal ligament injuries, and stable repair of the osseous-ligamentous avulsions.While these injuries were previously managed with the use of closed reduction and immobilization, authors of recent reports have recognized the instability of these complex injuries and have described treatment algorithms using open reduction and internal fixation. We report a case of ulnar radiocarpal wrist dislocation treated with wrist arthroscopy and percutaneous pinning without repair of the extrinsic wrist ligaments.
