Quick Reference

A condition usually caused by heavy lifting in ergonomically inefficient ways, in which a portion of the shock-absorbent nucleus pulposus that separates each vertebra from those adjoining it is extruded into the spinal canal, where it can exert pressure on the spinal cord or nerve roots, causing persistent pain, e.g., sciatica, and sometimes paraesthesia and/or muscle weakness. It is often occupational in origin.
