Nerve root injection

The indication for peri-radical treatment is irritating nerve root syndrome, which is often the result of a herniated disc and / or narrowing of the nerve roots as a result of degenerative changes in the spine (spinal stenosis). Here, the drug is injected directly into the exit point of the nerve root from the spinal canal.

The patient lies on the back or side over the computer tomography table. After the usual preparations and determining the area of ​​the spine to be treated, a mark is placed on the skin in this place, then the skin is sterilized repeatedly to begin the treatment. Under imaging guidance, a thin injection needle is pushed into the skin and muscles near the nerve root, and then tiny amounts of dye or air are injected to verify the correct location of the needle. Thus, drugs can be injected completely at the affected root, as well as a local anesthetic is injected around the nerve, and thus the pain is often reduced immediately, but it can cause a temporary feeling of numbness coinciding with or without a loss of energy in the legs or hands that lasts for hours and then disappears completely. . This type of treatment may be repeated.

This condition occurs in any part of the spine, but it is more common in the lumbar and cervical region and less common in the thoracic region.
