An summary of the Three different Types of Epidurals for Pain administration
Epidural cortisone injections recite an excellent rehabilitation selection for pain management patients suffering from spinal nerve irritation, which is also termed radiculitis.
The injections work well for leg pain advent from herniated discs along with radiculitis advent from the varied separate types of spinal stenosis, together with foraminal, central, and lateral stenosis. Also, epidural injections work well for radiculitis advent from disc problems. Can epidurals work well for back pain? Yes they can, but mostly they are for leg pain problems.

Cortisone spinal injections are really meant to get patients "over the hump". Cortisone puts "water on the fire" so to speak, allowing patients into rehab more comfortably and hopefully work and play with their kids and socialize. The cortisone doesn't fix whatever but they can temporarily do well with pain control.
Until we come up with something better, predominantly cortisone is injected. How well does it work?
It works by neural membrane stabilization along with blocking phospholipase A2 activity, and inhibiting neural peptide synthesis.
Local anesthetics by themselves have been shown to produce a prolonged dampening supervene of the dorsal horn and c-fiber activity. This may supply excellent pain relief by themselves without cortisone.
Fluoroscopic advice is the current accepted of care with epidural cortisone injections. Complicated studies have shown upwards of a 35% improper placement covering the epidural space without fluoroscopy.
Here are the separate types of injections along with some facts on each:
Caudal epidural injections - Indications consist of when it's tough to get to the other approaches with intra-laminar or transforaminal approaches. Commonly administered in post-surgical patients when transforaminal technique is not possible. There are also indications for a caudal injections with pelvic pain. These injections are least technically demanding. Need a larger volume to hit the targets, Commonly 10 milliliters are needed to reach L5-S1 and over 20 milliliters are need to reach above L4-5. The miss-rate without fluoroscopy for caudal epidurals is 40% agreeing to the literature.
Interlaminar Epidural Cortisone Injections - This type of injection allows for management of medication to higher lumbar levels. One of the biggest downsides to interlaminar collection is that it has the top incidence of dural tears which may lead to headaches (5%). Advantages consist of being fairly technically simple. It does require physicians being customary with the "loss of resistance" technique. It also allows for delivery of medication to areas higher in the spine than the caudal route. Often these injections are performed blind, without fluoroscopy, and this is a disservice to the patient. Study shows 30% misplacement without it.
Transforaminal Esi - The indication for Tesi is for radicular pain, with the rationale being delivering the drug in maximum attentiveness and closer to the site of pathology. There are Complicated studies demonstrating the efficacy. Disadvantages consist of very rare events of bad things happening. These injections are technically the most demanding, and there is a microscopic risk of direct nerve trauma. A study by Weiner in 1997 showed that these injections may be surgery sparing. There was a 46% rate of achieving unblemished pain relief. Complicated studies have shown that 2/3 of patients have been able to avoid surgery with these interventions. A 2010 study by Bogduk et al was a prospective randomized blinded study seeing at transforaminal epidurals with cortisone plus anesthetic, versus anesthetic alone versus saline in the epidural space. The study also looked at intramuscular injections without epidural injection. Well over 50% of patients received over 50% pain relief for the epidural injection with cortisone and lidocaine. Twenty five percent of the patients ended up pain free completely. The other groups achieved in the middle of 7% and 21% pain relief, so much less.
