Caudal Adhesionolysis of Scar Tissue

What is it?

This is a type of epidural injection that is used to break up scar tissue that may be trapping nerves and causing pain.

How it is performed

The epidural space (a place close to but outside of the spinal cord) is entered through the sacral hiatus (near the tail bone). X-ray is used to guide the needle to the right spot. A catheter then may be inserted through the needle. Dye is injected and pictures are taken to look for areas of scar tissue. Once the scar tissue areas are determined, medications such as hypertonic saline or local anesthetic and steroid may be injected to break up scar tissue and alleviate pain.

What patients are candidates?

Patients with a history of back surgery may be candidates.

How long does the procedure take?

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.
