Thoracic spine: It means that there is a small amount of narrowing around the spinal cord (the thecal sac) due to some early arthritis from the little joints behind the spinal cord. It does not sound worrisome, and is merely a imaging finding, rather than something that is clinically significant i believe. I would have to see to scan to be sure though. Thank you.

Facet changes: The facet joints are positioned in the spine like wheels of a tricycle. The front wheel is the disc, the facets the two smaller wheels in back. In the center, seat area, is the spinal cord. Arthritic changes cause the facet joints to narrow or spur, and the sheet of ligament near them to thicken. In a single word, this indicates "arthritis.".
