13 Possible Causes for Narrowing of Medullary Canal, Pyramidal Tract Signs

  • Cervical Myelopathy

    This narrowing in the lower back (lumbar canal stenosis) produces only radiculopathy (pinched nerve) because the tip of the spinal cord called the conus medullaris is at the[necksolutions.com] Typically, this stenosis is from degenerative changes, a herniated disc, and one may have a predisposition from a congenitally narrowed spinal canal which is genetic.[necksolutions.com]

  • Spinal Cord Compression

  • Klippel-Feil Syndrome

    Various mechanisms of neural complications have been studied in the literature: medullary abnormality, spinal instability, narrowing of the cervical canal, and vascular dysfunction[ispub.com]
