  • Systems for vertebral adjustments and rod reduction
    Patent number: 9968386
    Abstract: An instrument for compression and distraction of a vertebral segment and reducing a surgical rod includes a first arm, a second arm, a coupler, and a reducer. The first arm includes a first aperture for receiving a first screw extender that attaches to a first vertebra. The second arm pivotably couples to the first arm and includes a second aperture for receiving a second screw extender that attaches to a second vertebra. The coupler links the first arm to the second arm to position the first arm relative to the second arm for compression and distraction of the first vertebra relative to the second vertebra. The reducer is received within the second aperture for reducing a surgical rod within the second screw extender.
