Volar locked plate fixation of a displaced left intraarticular distal radius fracture showing (A) a PA view (with volar tilt neutralized) confirming extraarticular placement of the radial styloid screws as they are heading toward a concave articular surface, and (B) a lateral view with radial inclination neutralized confirming subchondral non-styloid screws toward a concave articular surface. Screws heading dorsally are headed toward a convex articular surface, so an infinite number of fluoroscopic views are technically needed to judge appropriate screw lengths
