Nerve Root Injections

  • At each level of the lumbar spine a nerve root passes
    out to supply the legs with sensation and
    muscle power.
  • The nerve root can become irritated or compressed
    causing pain, loss of sensation or weakness
    in the legs.
  • NRI (which is a steroid and a numbing agent) injected
    to the nerve root, helps to relieve these symptoms.
  • A dye is also added and fluoroscopy is used to track
    the medication, ensuring that the medication is
    delivered to the correct location.
  • The steroid also helps reduce inflammation around
    the nerve root.
