Abstract
A method of operating a rod reducer includes connecting a cam coupling rod reducer to a screw head of a pedicle screw assembly, wherein spaces in between prongs at a second end of an inner tube of the rod reducer are positioned parallel to a rod of the pedicle screw assembly, and wherein the connection of the cam coupling rod reducer to the screw head indicates a first position of operation; rotating a lever cam of the cam coupling rod reducer until an indication line marked on an outer body of the cam coupling rod reducer moves to a second position of operation; and rotating the lever cam to a third position of operation, wherein the third position of operation indicates that the rod is optimally seated in the pedicle screw assembly, and that the pedicle screw assembly is ready to accept a blocker screw.
