Epidural steroid injections are performed to provide long-term pain relief from radicular pain. During the procedure the anesthetic and corticosteroid solution is introduced into the epidural space. The epidural space is the area around the spinal cord or its extension inside of the spinal canal which consists of fat and small blood vessels.
Different approaches are used to perform epidural steroid injections:
Interlaminar epidural steroid injection
Transforaminal epidural steroid injection
Caudal epidural steroid injection
