Unlike the cranial epidural space, the spinal epidural space contains adipose tissue, the internal vertebral venous plexuses and the spinal nerve roots. [1] The spinal epidural space spans the length of the spinal cord, from the foramen magnum superiorly to the sacral hiatus inferiorly. [6] Epidural space is the smallest at the cervical region ...
Epidural steroid injection (ESI) is a technique in which corticosteroids and a local anesthetic are injected into the epidural space around the spinal cord in an effort to improve spinal stenosis, spinal disc herniation, or both. It is of benefit with a rare rate of major side effects.

ICD-9-CM 03.90 MeSH OPS-301 code 8-910 [edit on Wikidata] Epidural administration (from Ancient Greek ἐπί, "upon" + dura mater) is a method of ...
For epidural anesthesia an anesthetic agent is injected into the space just outside the thecal sac and diffuses through the dura to the nerve roots where they exit the thecal sac. [4] [5] For spinal anaesthesia in general, an injection can be given intrathecally into the subarachnoid space, or into the spinal canal.
The spinal needle is then withdrawn and the epidural catheter inserted in the standard manner. Alternatively, a two-level approach may be undertaken. The epidural space is first located in the standard manner. Then, at another level, a standard spinal is performed. Finally, the epidural catheter is threaded through the Tuohy needle.
In the spine, the epidural space is an anatomic space that is the outermost part of the spinal canal. It is the space within the canal (formed by the surrounding vertebrae ) lying outside the dura mater (which encloses the arachnoid mater , subarachnoid space , the cerebrospinal fluid , and the spinal cord ).
