Lunate dislocation on radiography

A radiograph of the right wrist in A-P projection (A) shows a lunate dislocation (arrow), distal radial fracture (arrowhead), and ulnar styloid fracture (dashed arrow). Image B is a normal wrist in A-P projection and shows the normal appearance of the lunate (asterisk). Image C is a lateral projection and shows a dislocated lunate (asterisk). Image D is a normal lateral projection of the wrist and shows the position of the lunate (asterisk).
