What You Should Know About Epidural Steroid Injection (ESI) For Back Pain

Back pain is one of the most common reasons people seek medical treatment, with millions of individuals affected worldwide. If you’ve experienced chronic back pain and have been unable to find relief through conventional methods like physical therapy, medication, or rest, an Epidural Steroid Injection (ESI) might be recommended. This minimally invasive procedure has been a cornerstone of back pain treatment, offering relief to patients and allowing them to regain mobility. In fact, ESIs are a widely used therapy for managing chronic pain, with healthcare providers performing approximately 9 million epidural steroid injections each year in the U.S. alone.

At Big Apple Spine & Orthopedics, Dr. Arutyunyan specializes in advanced, evidence-based approaches for back pain management, including ESIs. Let’s dive into the essentials of this procedure, how it works, and why it could be the solution you’ve been searching for.

Understanding Epidural Steroid Injections

What Is an Epidural Steroid Injection?

An Epidural Steroid Injection (ESI) is a minimally invasive procedure designed to relieve pain caused by inflammation of spinal nerves. The injection delivers a corticosteroid (a potent anti-inflammatory medication) and, in some cases, a local anesthetic into the epidural space around the spinal cord. This combination helps reduce inflammation and alleviate pain associated with conditions like:

What Are Other Common Names for Epidural Steroid Injections?

You may hear epidural steroid injections referred to by several other names, depending on the medical provider or context. Some of the most common alternatives include:

  • Spinal steroid injection
  • Epidural injection for back pain
  • Corticosteroid injection (epidural)
  • Lumbar epidural injection
  • Nerve root injection

These terms are often used interchangeably, so if your specialist at Big Apple Spine & Orthopedics mentions any of these phrases, they’re talking about the same minimally invasive pain-relief technique.

  • Herniated discs
  • Spinal stenosis
  • Degenerative disc disease
  • Sciatica
  • Spondylolisthesis

Types of Epidural Steroid Injections

ESIs aren’t a one-size-fits-all solution—there are several types, each tailored to target pain in different regions of your spine or to access the epidural space using specific approaches. Understanding these variations can help you and your provider determine the best pathway for relief.

Based on the Part of the Spine Treated

  • Cervical (Neck) ESI: This injection is administered into the area near your cervical spine. It’s commonly recommended for pain radiating from the neck down the arms, often due to herniated discs, bone spurs, or narrowing of the spinal canal in the neck region.
  • Thoracic (Upper/Mid-Back) ESI: Targeting the upper and mid-back, thoracic ESIs are an option for those experiencing discomfort caused by conditions like thoracic disc herniations or spinal stenosis.
  • Lumbar (Lower Back) ESI: The most frequent type, lumbar ESIs are delivered to the lower back. They aim to relieve classic lower back and leg symptoms—think sciatica—from issues such as herniated discs, degenerative disc disease, or spinal stenosis.

Based on the Injection Pathway

  • Interlaminar ESI: Here, the needle is guided between two adjacent bones (laminae) in your spine, placing the medication in the back part of the epidural space.
  • Transforaminal ESI: This route uses the natural openings where nerve roots exit the spine (foramina), allowing for medication to be delivered with pinpoint accuracy directly to the irritated nerve.
  • Caudal ESI: For patients who need medication delivered to the lowest portion of the spine, the caudal approach reaches the epidural space through a small opening near the base of the sacrum (just above your tailbone).

Each technique has its own set of advantages, which your spine specialist at Big Apple Spine & Orthopedics will discuss with you based on your specific symptoms and diagnostic findings.

What Are Interlaminar, Transforaminal, and Caudal ESIs?

Epidural steroid injections can be administered in a few different ways, depending on the location of your pain and the unique structure of your spine. Each approach takes a slightly different path to reach the epidural space.

  • Interlaminar ESI: This technique involves guiding the needle between two of the bony arches (called laminae) in your back. Think of the lamina as protective plates forming the spinal canal’s outer wall. By threading the needle between them, medication is delivered near the affected nerves.
  • Transforaminal ESI: With this method, the needle travels through a natural opening on the side of your spine known as the foramen. This is where nerve roots branch off from the spinal cord. A transforaminal injection can target a specific nerve that’s causing pain—like a courier delivering a package right to your front door.
  • Caudal ESI: For issues affecting the lower spine, the caudal approach uses a small opening at the base of the sacrum (just above your tailbone). This lets your physician access the epidural space at the very bottom of your spine, addressing pain that may radiate down into your legs.

Each type has its advantages, and your specialist at Big Apple Spine & Orthopedics will help choose the most appropriate approach to suit your condition and maximize relief.

What Are Cervical, Thoracic, and Lumbar ESIs?

Epidural Steroid Injections are tailored according to the location of your pain, targeting different regions of the spine:

  • Cervical ESI: This injection is administered near the neck, aiming to treat pain that often radiates from the neck down into the arms due to conditions such as herniated discs, bone spurs, or cervical spinal stenosis.
  • Thoracic ESI: Placed in the upper or middle back, thoracic ESIs are recommended for those with mid-back pain that may stem from thoracic disc herniations or narrowing of the spinal canal in this area.
  • Lumbar ESI: Delivered to the lower back, lumbar ESIs are commonly used for pain that starts in the lower back and can travel down the legs, often caused by lumbar disc issues, degenerative disc disease, or spinal stenosis.

Your physician will select the appropriate injection site based on your symptoms and the underlying spinal condition, ensuring the medication reaches the nerve roots responsible for your discomfort.

How Are Epidural Steroid Injections Classified?

Just as there are different roads that lead to the Big Apple, there’s more than one way to approach an Epidural Steroid Injection. ESIs are typically classified in two main ways: by where along your spine the medication is delivered, and by the specific technique your provider uses to reach the epidural space.

Classification by Location: Cervical, Thoracic, and Lumbar

Depending on where your pain is located, your doctor may recommend one of the following:

  • Cervical (Neck) ESI: Injected into the neck area—this is the go-to for radiating neck pain or arm symptoms often caused by herniated discs or cervical stenosis.
  • Thoracic (Upper/Mid-Back) ESI: Delivered into the upper or mid-back region, targeting pain originating from thoracic disc issues or spinal narrowing.
  • Lumbar (Lower Back) ESI: The most common variety, injected into the lower back to address sciatica, leg pain, or lower back conditions like lumbar disc herniation and spinal stenosis.

Classification by Technique: Interlaminar, Transforaminal, and Caudal

Think of these as different navigation routes to the epidural space:

  • Interlaminar ESI: The needle passes between two vertebral bones (the laminae) to reach the epidural space directly from the back. It’s somewhat like taking the most direct subway line to your stop.
  • Transforaminal ESI: Here, the needle travels through a small opening (the foramen) where nerve roots exit the spine, allowing the medication to be delivered right where irritated nerves are located.
  • Caudal ESI: A more “scenic route,” this approach accesses the epidural space through an opening just above the tailbone, making it useful for reaching the lowest areas of the spine.

Your specialist at Big Apple Spine & Orthopedics will decide which location and technique best match your symptoms and spinal anatomy, ensuring the greatest chance for targeted relief.

How Are Epidural Steroid Injections Different from Epidurals Used in Labor or Surgery?

It’s important to note that an epidural steroid injection (ESI) isn’t the same thing as the epidural anesthesia or analgesia you might receive during childbirth or certain surgeries. While all of these procedures involve placing medication into the epidural space near the spinal cord, their purposes and effects are quite different.

  • ESIs are primarily used to reduce inflammation and pain in the spine by delivering a corticosteroid (sometimes with a local anesthetic) to calm irritated nerves.
  • Epidural anesthesia or analgesia for labor and surgery, on the other hand, uses a larger dose of local anesthetic to numb specific areas of the body, providing significant pain relief but without the anti-inflammatory benefits of a steroid.

So, although both procedures share the term “epidural,” the medications used—and the reasons for using them—are distinct.

How Does an ESI Work?

When inflammation occurs in the spinal nerves, it can cause radiating pain, numbness, or weakness in the back, legs, or arms. The corticosteroid in the ESI reduces this inflammation, while the anesthetic provides immediate, albeit temporary, pain relief.

By targeting the source of the pain, an ESI not only alleviates symptoms but also enables patients to participate in physical therapy and other rehabilitation efforts more effectively.

The Role of ESIs in Comprehensive Back Pain Treatment

At Big Apple Spine & Orthopedics, ESIs are part of a comprehensive, personalized back pain treatment plan. Dr. Arutyunyan, a leading Spine Surgeon in NYC, emphasizes a multidisciplinary approach that combines minimally invasive procedures with long-term strategies like physical therapy, ergonomic adjustments, and lifestyle changes.

The ESI Procedure: Step-by-Step Overview

Understanding what to expect during the ESI procedure can help ease any concerns and ensure you’re well-prepared:

  1. Pre-Procedure Consultation

During your initial consultation, Dr. Arutyunyan will review your medical history, perform a physical examination, and may order imaging studies like an MRI or CT scan. This helps determine the precise location of the pain and ensures that an ESI is the right course of action.
2. Preparation

On the day of the procedure, you’ll lie face down on a specialized table. The injection site will be cleaned and sterilized to prevent infection. Local anesthesia is typically administered to numb the area.
3. Guided Imaging

Using fluoroscopy (a type of live X-ray), Dr. Arutyunyan will carefully guide a needle into the epidural space. Contrast dye is often used to ensure precise placement.
4. Injection

Once the needle is in place, the corticosteroid and anesthetic mixture is slowly injected. You may feel mild pressure but should not experience significant pain.
5. Post-Procedure Monitoring

After the injection, you’ll be monitored for a short period before being discharged. Most patients can return home the same day and resume normal activities within 24 hours, though heavy lifting and strenuous exercise should be avoided temporarily.

Benefits of Epidural Steroid Injections

  1. Targeted Pain Relief

By delivering medication directly to the source of inflammation, ESIs provide faster and more effective relief compared to oral medications.

  1. Minimally Invasive

Unlike surgery, ESIs require no incisions, making the procedure low-risk and ideal for patients who want to avoid invasive interventions.

  1. Improved Mobility

Pain relief from an ESI can help patients regain the ability to perform everyday tasks and participate in physical therapy.

  1. Complementary to Other Treatments

ESIs work well in conjunction with other back pain treatments, such as chiropractic care, physical therapy, and lifestyle modifications.

Potential Risks and Side Effects

While ESIs are generally safe, there are some potential risks and side effects to consider. Dr. Arutyunyan ensures that all patients at Big Apple Spine & Orthopedics are fully informed before proceeding. Common risks include:

  • Temporary pain at the injection site
  • Headache
  • Infection (rare)
  • Nerve damage (extremely rare)
  • Temporary increase in blood sugar levels

If you experience any unusual symptoms post-procedure, contact your healthcare provider immediately.

Who Is a Candidate for an ESI?

Not everyone with back pain is a candidate for an ESI. This treatment is typically recommended for individuals who:

  • Have not found relief with conservative treatments like medication and physical therapy.
  • Experience radiating pain (e.g., sciatica) or nerve-related symptoms.
  • Want to avoid or postpone surgery.

Dr. Arutyunyan conducts a thorough evaluation to ensure that ESIs are suitable for each patient’s specific condition.

How Effective Are Epidural Steroid Injections?

The effectiveness of ESIs can vary depending on factors like the underlying condition, the severity of inflammation, and individual response to the treatment. Many patients report significant pain relief lasting weeks to months. For some, periodic injections may be necessary to maintain results.
