Radiculopathy is the term for neuropathy that affects nerve roots. The nerve roots are extensions of spinal nerves. They exit the spinal canal through a space between vertebrae, called the neural foramen. Degeneration of vertebral bone, herniation of the pulpy disc between vertebrae, narrowing of the spinal column (spinal stenosis), or trauma can compress or cut nerve roots and cause neuropathy.
