radiculopathy caused by spinal spondylosis

Last reviewed 01/2018

There are two types of radiculopathy caused by spinal degenerative processes:

  • compressive neuropathy:
    • disc herniation
    • osteophyte formation
    • cause compression of the nerve roots
    • treatment is to relieve compression:
      • laminectomy
      • discectomy

  • non-compressive neuropathy:
    • disc degeneration
    • is a biochemical rather than a biomechanical disorder with substance P and fibrinolysis playing a role
    • treatment consists of complete removal of the disc with fusion of the anterior or posterior (or both) vertebral bodies

There is often a mixed picture of compressive and non-compressive pathology in a degenerate spine (1).
