Overview and Indications for Procedure:
Lumbar transformational Steroid Injections (With X-ray Guidance) are used to reduce pain, improve function and enabling patient to pursue physical Therapy/Rehabilitation and return to work, sports and daily /leisure activities. Its main indication is to decrease the inflammation associated with a variety of spinal conditions, such as herniated disc, sciatica, spinal stenosis, degenerative disc disease with nerve root impingement. There seems to be a better response when the injections are coupled with an organized therapeutic exercise program, activity modification and ergonomic corrections.
Risk Associated with procedure:
It is important to know risk associated with any medical or surgical treatment. , There are few risks associated with Lumbar epidural steroid injections and they tend to be rare. The potential risk includes:
- Immediate or delayed ALLERGIC reaction to medication use
- Nerve or spinal cord Injury
- Dural Puncture
- Temporary increase in pain
- High blood sugar levels
- Transient vaginal spotting
- Transient facial flushing
- Spinal vascular injury or vascular uptake of particular steroid
Infection rate is less than 1% in patients receiving spinal injections performed under sterile conditions. The bleeding complication is more common in patients with history of bleeding disorder, patients being treated with anticoagulant/antiplatelet medications and patients taking over the counter medication like Motrin and Aspirin. The frequency of injury to the nerve roots or spinal cord has substantially reduced with use of fluoroscopy and contrast material. It is rare to encounter nerve root or spinal cord Injury with epidural injections. The rate of nerve injury and spinal cord injury is higher in obese patients due to poor visualization of the target on lateral X-rays. Dural puncture is an infrequent complication and may cause a positional headache (headache in seated and standing position but not on laying down position). This type of headache is often self-limiting, although in persistent cases, a blood patch may be necessary to alleviate the headache. Elevated blood sugar is a known effect of steroid medication and may last for 2-4 days after the injection of steroids. Patients on insulin will be following sliding scale to adjust for elevated sugar levels. Patients on oral medication should follow primary care advice regarding temporary increase in oral medication to accommodate for blood sugar levels
Following side effects tend to be rare, though they become more common when steroids are taken daily for several months. These risks and side effects may include:
- A transient decrease in immunity
- Stomach ulcers
- Severe arthritis of the hips (avascular necrosis)
- Increased appetite
- Agitation and irritability
- Negative effect on bone density and fractures
Who should avoid transforaminal epidural steroid injections?
Lumbar Transforaminal Epidural Steroid Injections should not be performed following conditions:
- In individuals with known allergies to local anesthetics, steroids or contrast material
- Patients with local or systemic bacterial infection
- Pregnant Patients
- Patients with bleeding disorders
- Patients suffering from a tumor or infection of the spine
- Uncontrolled congestive heart failure or diabetes
- When risk of holding certain mediations (Aspirin, antiplatelet drugs/blood thinners) outweighs benefit of the epidural procedure
Prepare for your Procedure:
Certain medications have to be held before elective spinal procedures. A list of such medications is on the last few pages of this education al material. Do not hold such medication on your own and ask your PCP /Cardiologist if it is safe to stop such medication before the procedure. Continue to take all other medications, especially your Blood Pressure and diabetes medications.
A sample of medications that has to be held includes:
1. Aggrenox® (dipyridamole)
3. Coumadin® (warfarin)
4. Effient® (prasugrel)
5. Fragmin® (dalteparin)
6. NSAIDS (see sample below)
7. Herbal blood-thinners
9. Eliquis ® (apixaban)
10. Lovenox® (enoxaparin)
11. Plavix® (clopidogrel),
12. Pradaxa® (dabigatran)
13. Ticlid® (ticlopidine)
NSAIDS to be held (such as Ibuprofen, Motrin, Naproxen, Advil, Nabumetone, Diclofenac, Etodolac, Indomethacin, Ketorolac, Meloxicam, Piroxicam, Ketoprofen, Oxaprozin)
Please let us know if you have had fevers, antibiotic treatment, any illness, or hospitalization within the last 4 weeks. You must be healthy and off all antibiotics on the day of the procedure
Make sure you are not Pregnant at the time of procedure. Do a Urine Pregnancy Test the night before your spinal injection and report the results to the nurse before the procedure. Exposure to X-ray (used during spinal procedure) is known to result in birth defects and possible miscarriage. If in doubt, cancel and reschedule your procedure until you can confirm that you are not pregnant.
Day of your procedure:
- Please take a shower, wash the skin with normal soap and DO NOT put skin lotions or mediated creams in the area of the injection .Wear dark and loose clothing and undergarment.
- Arrive 30 minutes early and come with someone that can give you a ride home. Your procedure should take less than 30 minutes and your total time from greeting to end should be less than 90 minutes.
- Bring an updated list of your medications and allergies. Please point out if you are allergic to Contrast, Iodine or Latex.
- Bring your latest MRI /CT /imaging studies and the report with you.
- Do not eat or drink for 2 hours before your appointment. Diabetics may have a light meal.
- After check-in, an ID wristband containing your name and allergies will be placed on your wrist. A nurse or medical assistant will go over your meds and allergies and ask few screening questions. Then a nurse will go over final preparation before the procedure. If necessary an IV line will be placed particularly if this is your first spinal procedure.
- In rare cases, oral sedation is needed to reduce anxiety associated with the procedure. This will slow down the entire process. Take medication 1 hour before the procedure and you must have someone drive you to and from the procedure. Without the ride, procedure would likely be canceled.
During the procedure:
- You will change into a gown. You will be escorted to the procedure by a nurse and a consent form will be reviewed/ signed before the procedure. You will be asked to lay on your stomach
- Blood pressure and heart rate monitor will be placed on your arm/finger. Every medical equipment produces loud noises (beeping, alarms) and you should not be concerned.
- Intermittently your doctor will talk to staff in the procedure room and instruct them to perform a task. Your physician will guide you step by step through the procedure.

- When your physician is ready, X-ray unit is placed over your spine to identify the target.
- Skin will be marked and anesthetized (you will feel small pinch and burning sensation at each spot). It is normal to feel pressure or muscles twitching as needles are advanced to the final target.
- Once needle is at radiographic target, a small amount of contrast is injected to confirm final needle position before injecting steroid medication. You may feel transient pressure in your spine.
- Once procedure is completed, needle is removed, skin is cleaned and bandage is applied. You are then transferred back to the recovery area for observation.
Right after the procedure:
- You will be observed for 15-45 minutes.
