Selective nerves root blocks

What is it:

Selective nerves root blocks is a procedure that targets specific nerves and relieves the pain caused by inflammation. To ensure proper placement of the medication the procedure is done under fluoroscopy or x-ray.
There are two types of selective nerve root blocks: diagnostic and therapeutic. When one does a diagnostic block, just enough medication is placed to numb exactly one root. By doing this, the doctor can determine if the nerve root is causing the pain. Therapeutic blocks involve more medication and different medication.
Nerve roots are attached to the spinal cord. One exits each side of the spine at every vertebral level. These nerves carry signals throughout the body from the skin to the muscles. When one of the nerve roots is irritated, patients may experience pain, numbness, tingling, and sometimes weakness down an arm or a leg. A diagnostic selective block can be used to prove that a pinched nerve is the problem.

Purpose:

SNRB(Selective nerves root blocks) is a procedure that is performed to determine if a specific spinal nerve is the source of pain. By injecting steroid medication the inflammation is reduced thus alleviating the pain

How is it Done:

First an IV is started and you may be given medicine for relaxation if you so desire. Next, while lying on an x-ray table your skin will be cleansed and prepared. A local anesthetic is given to numb the skin surface. A physician locates under fluoroscopy a specific nerve root. A needle is then inserted and an anesthetic and steroid medication is injected into the area bathing the nerve root.
