Abstract
A spinal rod reducer for reducing a rod into a rod-receiving opening of a bone anchor comprises an elongate tubular body having a lumen extending therethrough and a pair of spaced flexible anchor attachment members at the distal end of the tubular body. A threaded rod reduction member having a rod contacting surface is supported for axial movement within the lumen. A threaded rotatable reduction knob is threadably engaged with the rod reduction member rotation of which causes the rod reduction member with the rod contacting surface to move axially distally toward the bone anchor. A locking sleeve is configured to axially slide on the tubular body over the attachment members, the locking sleeve including a locking element for releasably coupling the locking sleeve and the rod reduction member for selective independent and joint movement relative to the tubular body.
