The epidural space of a spine is the space between the outermost layer and the bone. The epidural space is outside of the spinal cord and extends from the base of the skull to the tailbone. Nerve roots exit from the spinal cord and then come together to form nerves. Epidural and nerve root injections are performed under x-ray guidance in a procedure suite for precise location. Conscious sedation may be provided upon prior approved request. The physician will then deliver a local anesthetic. Using a spinal needle, the physician then delivers the corticosteroid into the epidural space or selected nerve root. Relief of pain and inflammation may take five to seven days, however maximum relief may take up to two weeks. Epidural and nerve root injections provide long term relief, lasting weeks to months.
Reason for the procedure
This injection is performed to relieve spinal pain as well as any radicular pain. The steroid medication can reduce the swelling and inflammation caused by spinal conditions such as spinal stenosis, radiculopathy, sciatica and herniated discs.
