Selective Nerve Root Block

What is a Selective Nerve Root Block (SNRB)?

One of the causes of pain that passes into the extremities is irritation of one or more nerve roots. The purpose of a Selective Nerve Root Block (SNRB) is to specifically block one or more spinal nerves to decrease pain. This is done by injecting an anesthetic and anti-inflammatory steroids into the space around the nerve for the nerve block.

A Selective Nerve Root Block is similar to an epidural steroid injection, but is more specific. This will help determine which particular nerve is related to your symptoms.

What Are The Purposes for a Selective Nerve Root Block?

A Selective Nerve Root Block (SNRB) ia a diagnostic procedure that is used to evaluate patients with:

  • radicular pain
  • stenosis
  • conditions that may result in nerve root compression
