Perilunate Dislocations and Fracture Dislocations/Radiocarpal Dislocations and Fracture Dislocations

By virtue of its complex anatomy, the human wrist is subject to a wide variety of injury patterns resulting from similar mechanisms of injury. The most common mechanism of injury occurs when force is transmitted through the wrist, ascending from a palmar contact as the patient resists a fall or other contact. The second major mechanism of injury occurs when the wrist itself is directly trapped between two hard objects and subjected to a crushing force. Other mechanisms are also possible but less frequent. The force transmitted through the tissues of the wrist becomes dissipated as energy is consumed to disrupt various structures, both bony and ligamentous. The force typically travels along identifiable pathways. Recognizing one injured structure that is more obvious leads the surgeon to identifying other injured structures that are less obvious.
