I recently had a bilateral lumbar laminotomy and bilateral
foraminotomy at L4/L5 to address a L5 radiculopathy in both feet. I am 9 weeks
post op with no change in the L5 radiculopathy in both feet. When I saw my
surgeon recently they said they decompressed the L5 nerve root by performing
the bilateral foraminotomy at L4/L5.
According to everything I am reading on Spine-Health, the L5
nerve root is traversing at the L4-L5 level and the L4 nerve root exits the
spine at the L4-L5 level. It appears to me the L4 nerve root was decompressed,
not the L5 nerve root, when the bilateral foraminotomy was performed at L4/L5.
NOTE: There was no disc herniation or protrusion at the L4/L5
Do I understand the relationship between lumbar levels and
nerve roots correctly?
