Abstract
Disclosed is a surgical alignment and distraction frame and associated methods of use that facilitates correction of a sagittal imbalance. The alignment and distraction frame works in conjunction with pedicle screw installation guide assemblies to impart the desired correction. The alignment frame can be utilized to ensure the pedicle screw housings are aligned (to facilitate rod coupling) in concert with the completion of a correction maneuver.
Claims20
A system, comprising:
- a spinal fixation construct configured to couple to a first vertebra and a second vertebra in a patient, the spinal fixation construct comprising:
- a first pedicle screw including a first shank coupled to a first rod housing,
- a second pedicle screw including a second shank coupled to a second rod housing, and
- a spinal rod configured to engage the first and second rod housings;
- and
- a first guide assembly configured to couple to the first pedicle screw;
- a second guide assembly configured to couple to the second pedicle screw;
- and
- a spinal alignment frame configured to align the first and second vertebra, the spinal alignment frame comprising:
- an elongate rack,
- a first coupler configured to couple to the elongate rack and the first guide assembly, and
- a second coupler configured to couple to the elongate rack and the second guide assembly.
A method for aligning spinal vertebrae and installing a spinal fixation construct in a patient, the method comprising:
- anchoring a first pedicle screw of the spinal fixation construct to a first vertebra, the first pedicle screw having a first shank coupled to a first rod housing;
- anchoring a second pedicle screw of the spinal fixation construct to a second vertebra, the second pedicle screw having a second shank coupled to a second rod housing;
- coupling a first guide assembly to the first pedicle screw;
- coupling a second guide assembly to the second pedicle screw;
- and
- coupling a spinal alignment frame to the first guide assembly and the second guide assembly to align the first vertebra and the second vertebra;
- and
- coupling a spinal rod of the spinal fixation construct to the first and second rod housings of the first and second pedicle screws, respectively.
