Nerve root block
A nerve root block is an inoculation of local anesthetic and steroid injected under X-ray direction into the area where the nerve exits the spinal column. A nerve root block is normally suggested by Orthopedic doctor when there is a pain in the arm or leg that holds the path of a single nerve.
It can be understood as a test to ascertain the source of the pain. If you get a period of sustained pain relief from the injection, the nerve block may be repeated. In some instances, the block is done to help distinguish whether or not surgery might be necessary and at what level such surgery might be most important.
In a Selective Nerve Root Block (SNRB), the nerve is addressed at the level where it moves out of foramen. The injection is executed both with a steroid and lidocaine. The Fluoroscopy is done to ensure that the medication is delivered to the correct location.
In cases where there the patient’s pain is checked post inoculation procedure, it can be inferred that the back pain generator is the particular nerve root that has just been injected. After the injection, the steroid likewise serves in reducing inflammation around the nerve root.
