    摘要： Devices, instruments, systems and techniques for guiding an implant to a location adjacent a bone anchor include a guide member with a connecting portion and a guiding portion. The connecting portion is adjacent the bone anchor, and the guiding portion extends proximally from the connecting portion and is adapted guide an implant therealong toward the bone anchor. The guiding portion is flexible to facilitate manipulation and implant placement in the patient's body.

    摘要： Instruments and methods for determining the spacing between locations in an animal subject are employed to size a connecting element to secure along a bony segment in the animal subject. The instruments and methods include a measuring instrument mountable to proximal ends of extensions extending from anchors engaged to the bony segment. The measuring instrument is configured to provide an indication of the spacing between the anchors even if the extensions are in non-parallel relation to one another.

    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.
