Patient EducationClinical
Spinal Cord Injuries
Your spinal cord is a bundle of nerves that runs down the middle of your back. It carries signals back and forth between your body and your brain. A spinal cord injury disrupts the signals. Spinal cord injuries usually begin with a blow that fractures (breaks) or dislocates your vertebrae, the bone disks that make up your spine.
