At least one arm extends laterally outwardly from the clamping mechanism and is configured to be positioned outside of the patient. The at least one arm has at least one hole oriented to align with a location on either the spinous process of the first vertebral body or a lateral location on a second vertebral body. The at least one hole is configured to guide an instrument to either the spinous process or to the lateral location on the second vertebral body.
