A disc ... occurs when the outer rim (annulus) of the disc weakens or tears, causing the nucleus to push outward.
When the disc herniates backward, to the right, or to the left it may impinge or "pinch" on a spinal nerve and/or the spinal cord, causing symptoms in the corresponding dermatome area. This is called a "...”, which may occur spontaneously or with trauma. Not all disc herniations cause impingement. As many as 30 percent of all adults have symptom-free bulges or minor herniations in the cervical area. Also, as many as 30 to 60 percent of all adults have disc bulges in their lower back that are entirely symptom free. Radiculopathy most commonly affects people between the ages of 30 and 50. |
