What is facet hypertrophy l Flatten the ventral thecal sac and encroach upon the lateral recesses abutment of the traversing nerve roots?

Pain and weakness. can result from compression of the nerves that exit at the level of the narrowing caused by bony overgrowth of the facets (the area where the vertebral bones meet) In the lumbar region the nerves exit at a higher level and "traverse" the space next to the facets below this before they exit the spinal canal at a lower level. Discuss this with your doctor.
