摘要：
A method of securing vertebrae includes inserting a first pedicle screw into a first pedicle of a first vertebra. The first pedicle screw includes a first channel running perpendicular to a first central axis of the first pedicle screw. The first pedicle screw has a first engagement structure. The method further includes inserting a second pedicle screw into a second pedicle of a second vertebra. The second pedicle screw includes a second channel running perpendicular to a second central axis of the second pedicle screw. The second pedicle screw has a second engagement structure. The method also includes inserting a guidewire through the first and second channels, threading a tether attached to an end of the guidewire through the first and second channels, securing the tether to the first pedicle screw, applying tension to the tether, and securing the tether to the second pedicle screw.
