Abstract
An instrument for multilevel compression and distraction of vertebrae in a spinal column includes a first arm, a second arm, a third arm, a linking member, and a coupler. The first arm includes a distal end with a first aperture for receiving a first screw extender that attaches to a first vertebra. The second arm includes a distal end with a second aperture for receiving a second screw extender that attaches to a second vertebra. The third arm includes a distal end with a third aperture for receiving a third screw extender that attaches to a third vertebra. The linking member pivotally links proximal ends of the first, second, and third arms. The coupler positions the distal ends of the first arm and the second arm relative to the third arm to compress and distract the first vertebra and the second vertebra relative to the third vertebra.
