Selective Nerve Blocks

What is it?

Selective nerve blocks are performed to determine if a specific spinal nerve root is causing pain. This procedure can reduce inflammation around the nerve root and decrease pain.

How it is performed

X-ray is used to help guide a needle close to the spinal nerve root. Once there, a small amount of contrast is used to outline the nerve root. Local anesthetic is then used to block the nerve root and provide temporary pain relief.

What patients are candidates?

Patients with inflamed nerve roots that may be causing them chronic pain are candidates for this procedure.

How long does the procedure?

20-30 minutes


Following the injection, the patient may be monitored for 20-30 min before being discharged to go home. Patients are usually asked to rest on the day of the injection.
