Laminectomy L1-4, diskectomy L3-4 in 3/12: right radicular pain. There are postoperative findings related to laminectomy at L1-4. There is a small disc protrusion eccentric to the right with an annular fissure at L3-4, as well as bilateral facet arthropathy with joint effusion. There is associated moderate right and mild left neural foraminal stenosis, but no significant spinal canal stenosis. There are slight disc bulges at L1-2, L2-3, and L4-5 and facet arthropathy, but no significant spinal canal or neural foraminal stenosis. There is no significant spinal canal or neural foraminal stenosis at L5-S1 either. The lumbar vertebral alignment is unchanged, without evidence of spondylolisthesis. There are scattered areas of degenerative endplate signal alterations. The vertebral body heights are preserved. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable.
