Method of measurement of distal radius alignment (representative case). Palmar tilt (PT): (1) Draw a line perpendicular to the long axis of the radius (A); (2) draw a line connecting the dorsal and palmar rims of the radius (B); and (3) measure the angle between lines A and B. Radial length (RL): (1) Draw a line on the distal ulnar articular surface (C); (2) draw a line on the radial styloid process (D); and (3) measure the distance between lines C and D. Radial inclination (RI): (1) Draw a perpendicular line to the long axis of the radius (E); (2) draw a line connecting the radial styloid process and ulnar border of the distal radius (F); and (3) measure the angle between lines E and F.
