Selective Nerve Root Blocks

Nerve roots are attached to the spinal cord and travel out of each spinal column’s side at every spinal level. They 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.

Nerve root blocks are commonly performed procedures for patients with a herniated disc, sciatica, swelling, or irritation in the nerve roots.

A specialized needle is placed near the exiting nerve root in question using fluoroscopy low dose x-ray. Anti-inflammatory medication is injected around this nerve. Sedation may be offered for patient comfort.

This procedure takes 20 to 30 minutes (depending on how many nerve roots are injected).

Selective Nerve Root Blocks

You may have some numbness for a short while after the block. You will be discharged when you can safely walk (expect to be in the center for 1-2 hours). When the procedure is over, the numbing medicine may make your legs feel temporarily weak. Therefore, you should limit your activity on the day of your procedure.
