SYSTEMS FOR VERTEBRAL ADJUSTMENTS AND ROD REDUCTION

摘要

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.

1. An instrument for compressing or distracting a first vertebra relative to a second vertebra and for reducing a spinal rod, comprising:
a first base portion that is configured to receive a first screw extender for attachment to the first vertebra; a second base portion that is configured to simultaneously receive a second screw extender for attachment to the second vertebra and a reduction tube to apply a reduction force on the spinal rod to position the spinal rod relative to the second screw extender; and a coupler that positions the first base portion relative to the second base portion to apply a compression or distraction force via the first screw extender and the second screw extender respectively.
