STEROID INJECTIONS
HOW ARE EPIDURAL STEROID INJECTIONS PERFORMED?
There are three common methods for delivering steroid into the epidural space: the interlaminar, caudal, and transforaminal approaches. All three approaches entail placing a thin needle into position using fluoroscopic (x-ray) guidance. Prior to the injection of steroid, contrast dye is used to confirm that the medication is traveling into the desired area. Often, local anesthetic is added along with the steroid to provide temporary pain relief.
An interlaminar ESI, often referred to simply as an ‘epidural injection’, involves placing the needle into the back of the epidural space and delivering the steroid over a wider area. Similarly, the caudal approach uses the sacral hiatus (a small boney opening just above the tailbone) to allow for needle placement into the very bottom of the epidural space. With both approaches, the steroid will often spread over several spinal segments and cover both sides of the spinal canal. With a transforaminal ESI, often referred to as a ‘nerve block’, the needle is placed alongside the nerve as it exits the spine and medication is placed into the ‘nerve sleeve’. The medication then travels up the sleeve and into the epidural space from the side. This allows for a more concentrated delivery of steroid into one affected area (usually one segment and one side). Transforaminal ESIs can also be modified slightly to allow for more specific coverage of a single nerve and can provide diagnostic benefit, in addition to improved pain and function.
All three procedures are performed on an outpatient basis, and you can usually return to your pre-injection level of activities the following day. Some patients request mild sedation for the procedure, but many patients undergo the injection using only local anesthetic at the skin.
WHY GET AN EPIDURAL STEROID INJECTION?
WHAT HAPPENS AFTER THE INJECTION?
The steroid will usually begin working within 3-5 days, but in some cases it can take a little longer to feel the benefits. Although uncommon, some patients will experience an increase in their usual pain for several days following the procedure. The steroids are generally very well tolerated, however, some patients may experience side effects, including a ‘steroid flush’ (flushing of the face and chest that can last several days and can be accompanied by a feeling of warmth or even a low grade increase in temperature), anxiety, trouble sleeping, changes in menstrual cycle, or temporary water retention. These side effects are usually mild and will often resolve within a few days. If you are diabetic, have an allergy to contrast dyes, or have other serious medical conditions, you should discuss these with your NASS doctor prior to the injection.
Epidural steroid injections have been performed for many decades, and are generally considered as a very safe and effective treatment for back and leg pain or neck and arm pain. Serious complications are rare, but could include allergic reaction, bleeding, infection, nerve damage, or paralysis. When performed by an experienced physician using fluoroscopic guidance, the risk of experiencing a serious complication is minimized. Overall, ESIs are usually very well tolerated and most patients do well.
Although not everyone obtains pain relief with ESIs, often the injections can provide you with improvement in pain and function that last several months or longer. If you get significant benefit, the injections can be safely repeated periodically to maintain the improvements. Injections are also commonly coupled with other treatments (medications, physical therapy, etc) in an attempt to either maximize the benefit or prolong the effects.
