Herniated Nucleus Pulposus. Definition. A herniated disc is a fragment of the disc nucleus which is pushed out of the outer disc margin, into the spinal canal through a tear or rupture.. In the herniated disc's new position, it presses on spinal nerves, producing pain down the accompanying leg. This produces a sharp, severe pain down the entire leg and into the foot.
A disc herniation is a large protrusion of the nucleus pulposus (center of the disc), which has burst through the annulus fiborsus (outer ring of the disc) into the spinal canal, invading the surrounding nerves and causing pain in the back, buttocks, hips, or legs. herniated disc is treated with conservative therapy unless there is a spinal deformity or neurologic deficit. Conservative therapy can include physical therapy, chiropractic care, acupuncture, Pilateâs, ultrasound, pain medication, muscle relaxants, and a short course of steroids.
