To position, the hand and wrist are placed PA, and the elbow is moved toward the body without moving the hand and wrist. Or, the hand can be turned medialward in extreme radial flexion (deviation). This position is used to better demonstrate the medial carpals (pisiform, triangular, hamate, and medial aspect of capitate and lunate) and their interspaces. In the proximal carpal row, the lunate is seen particularly well. Just medial to the lunate, the superimposed triquetrum and pisiform are seen. In the distal carpal row, the most lateral carpal, the hamate, is well seen. Just medial to it is the capitate. The self-superimposed and foreshortened scaphoid is seen distal to the radius and lateral to the lunate.
