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.
Epidural administration: injection into the epidural space of the spinal cord.Epidural, (Greek): situated on or outside the dura mater, from epi- "on top of" + dura mater + -al. Adhesion (Latin) adhēsiōn- for Latin adhaesiōn- (stem of adhaesiō) a clinging, equivalent to adhaes(us), past participle of adhaerēre to adhere + -iōn- -ion.
An alternative often employed is the injection of cortisone into the spine adjacent to the suspected pain generator, a technique known asepidural steroid injection. [212] Although this technique began more than a decade ago for FBS, the efficacy of epidural steroid injections is now generally thought to be limited to short term pain relief in ...
Medical intervention Epidural administration A freshly inserted lumbar epidural catheter. The site has been prepared with tincture of iodine, and the dressing has not yet been applied. Depth markings may be seen along the shaft of the catheter. ICD-9-CM 03.90 MeSH D000767 OPS-301 code 8-910 [edit on Wikidata] Epidural administration (from Ancient Greek ἐπί, "upon" + dura mater) is a method ...
Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF). It is useful in several applications, such as for spinal anesthesia, chemotherapy, or pain management. This route is also used to introduce drugs that fight ...
Transforaminal ligaments are not present in all individuals; when present, multiple types are oftener present. The most common type is the superior corporotransverse ligament. The ligaments have variously been reported to be identifiable in 17.8%-100% of individuals; the discrepancy is a result of inconsistent standards for their identification ...
The needle-through-needle technique involves the introduction of a Tuohy needle (epidural needle) into the epidural space. The standard technique of loss of resistance to injection may be employed. A long fine spinal needle (25G) is then introduced via the lumen of the epidural needle and through the dura mater, into the subarachnoid space.
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, measuring 1 to 2 mm. At L2 to L3, enlarges until 5 to 6 mm. It then enlarges progressively until lower lumbar and sacral region. [7]
