Would spinal decompression help this condition or is surgery the only option?
So in my eyes, your unconvertabral hypertrophy (extra growth of cartilege), is narrowing your foraminal holes at whatever the location was mentioned.
Unconvertabral hypertrophy means there is an extra growth of the cartilage located between the vertebrae. Foraminal narrowing means there's a narrowing of the space (hole) between the vertabrae where the nerve roots exit the spine.
