disc bulge and osteophytosis which effaces left L2 nerve root, moderate
disc protrusion, no significant spinal stenosis, severe left lateral recess
L3-L4: Mild intervertebral disc height loss, central disc protrusion
superimposed upon broad-based disc bulge, moderate bilateral facet
L4-L5: Postsurgical changes status post right hemilaminotomy. There is
redemonstration of central and right central disc extrusion which continues
to efface proximal right L5 nerve root and results in severe right lateral
