Caudal Epidural Steroid Injection

Steroid injections into the sacral epidural space through an opening at the base of the spine, just above the tailbone or coccyx are useful in patients with certain types of low back and leg pain. This technique is particularly useful in patients who have had previous back surgery. Medications injected through the caudal approach distribute through the epidural space and bathe the inflamed nerve structures in a mixture of local anesthetic, anti-inflammatory medication, and steroid solution to attempt to decrease inflammation and pain.
