Lunate dislocation

A 38 year-old patient was admitted to the emergency department after road accident due to pain on palpation of the right wrist, the 1st and the 2nd finger of the right hand. The patient was subsequently referred for an X-ray. Following the proper positioning of the patient and the systematic analysis of the wrist X-ray (PA and lateral view), a lunate dislocation was diagnosed (Fig. A). A CT scan of the right wrist was then performed, at the request of the surgeon, which clearly demonstrated the lunate dislocation and an additional triquetral fracture (Fig. B)
