Total bodily extrusion of the lunate: An extreme inferior arc injury: A case report

Case: A fifty-six-year-old man had an open radiocarpal and intercarpal dislocation with a radial styloid fracture, an open triangular fibrocartilage complex tear, and complete bodily extrusion of the lunate. We performed irrigation and debridement and an immediate total wrist arthrodesis. One year postinjury, the fusion had healed without infection, and the patient had functional digital range of motion, 80° of active pronation, and 60° of active supination without distal radioulnar joint instability; he had only mild pain with strenuous activities. Conclusion: In this severe case, we believed that total wrist arthrodesis was the most reliable treatment option, and it produced an acceptable result.
