Abstract
Official abstract text for this publication.
Embodiments disclosed herein provide compression/distraction methods and tools useful for fitting a spinal stabilization system in a patient through minimally invasive surgery. The spinal stabilization system may comprise screws anchored in vertebrae. The vertebrae may need to be compressed or distracted. One embodiment of an instrument disclosed herein may comprise a shaft for engaging one of the screws through an extender sleeve. A driver may engage another screw through an opening of the instrument. Through this engagement, a surgeon may use the rack and pinion of the instrument to compress or distract one or more levels of the vertebrae in a parallel motion, which can be advantageous clinically in certain situations.
