Abstract

A rod reducer assembly is provided and is selectively mountable to a pedicle screw assembly. The pedicle screw assembly includes a pedicle screw housing that defines a rod-receiving recess. The pedicle screw assembly includes an extension assembly that is coupled to the pedicle screw housing by a frangible member. The rod reducer is configured to reduce a spinal rod into the rod-receiving recess of the pedicle screw assembly. The rod reducer assembly may include a derotation sleeve configured to inhibit the frangible member from breaking while manipulating a spinal bone.
