What does this mean Mild annular bulge facet hypertrophy bilaterally 3mm posterior central protrusion?

The phrase describes findings from an imaging study, likely of the spine. A "mild annular bulge" indicates a slight outward protrusion of the intervertebral disc's outer layer, while "facet hypertrophy bilaterally" refers to enlargement of the facet joints on both sides, which can indicate Arthritis or wear. A "3mm posterior central protrusion" signifies that the disc material has bulged backward toward the spinal canal by 3mm, potentially causing nerve compression. Overall, these findings suggest some degenerative changes in the spine, which may lead to discomfort or pain.
