The REX Anterior Cervical Plate System consists af a variety size of main plates, screws, subplots, rivets and associated instruments. The sub-plate is pre-assembled to the main plate and designed to prevent screws from backing out using the elastic behavior during the screw insertion.

The rivets are also pre-assembled to the main plate and designed to assemble the sub-plate to the main plate firmly. Each component is subjected to a color anodizing process to differentiate the screw type and diameter and to make the surgical process easy. Main plate has windows in the middle of plate.
