What it is
Cervical myelopathy occurs when the spinal cord itself is compressed within the neck, usually by a combination of disc herniation, ligament thickening, and bone spurs (osteophytes) associated with degenerative cervical disc disease. Unlike radiculopathy — which affects a single nerve root — myelopathy disrupts the spinal cord and can cause symptoms in the arms and legs simultaneously. Left untreated, the neurological damage may become permanent.
