What are Lumbar Epidural Steroid Injections & How Are They Used?


June 20, 2024

Lumbar epidural injections are a common and effective treatment option for individuals experiencing lower back pain, sciatica, and other spinal-related conditions. These injections involve the administration of anti-inflammatory medication directly into the epidural space, the area surrounding the spinal cord and nerve roots in the lower back. By reducing inflammation and pain, lumbar epidural injections can provide significant relief and improve a patient’s quality of life.

In this comprehensive article, we will explore the anatomy of the lumbar spine, the common conditions treated with lumbar epidural injections, how the procedure works, what to expect during the treatment, and frequently asked questions. By the end of this guide, you will have a thorough understanding of lumbar epidural injections and whether this treatment may be right for you.

Understanding the Anatomy of the Lumbar Spine

The lumbar spine, also known as the lower back, is composed of five vertebrae (L1 to L5) and is responsible for supporting the upper body and providing flexibility for movements such as bending, twisting, and lifting. Between each vertebra, there is a disc that acts as a cushion, absorbing shock and allowing for smooth movement.

The spinal cord runs through the center of the vertebrae, and the nerve roots branch out from the spinal cord through small openings called foramina. These nerve roots are responsible for transmitting sensations and signals to and from the lower extremities.

Understanding the anatomy of the lumbar spine is crucial in comprehending how lumbar epidural injections work and the conditions they can address.

Common Conditions Treated with Lumbar Epidural Injections

Lumbar epidural injections are commonly used to treat a variety of spinal-related conditions, including:

  1. Herniated or Bulging Disc: A herniated or bulging disc occurs when the soft, inner portion of the disc protrudes through the outer, tougher layer, putting pressure on the surrounding nerve roots and causing pain, numbness, and weakness.
  2. Spinal Stenosis: Spinal stenosis is a condition in which the spinal canal narrows, resulting in compression of the spinal cord and nerve roots. This can lead to pain, tingling, and numbness in the lower back, legs, and feet.
  3. Degenerative Disc Disease: Degenerative disc disease is a condition in which the intervertebral discs in the spine begin to break down, leading to pain, stiffness, and reduced mobility.
  4. Sciatica: Sciatica is a term used to describe the pain, tingling, and numbness that radiates down the leg, often caused by a compressed or irritated sciatic nerve.
  5. Spondylolisthesis: Spondylolisthesis is a condition in which one vertebra slips forward over the vertebra below it, causing pain and instability in the lower back.

By administering anti-inflammatory medication directly to the affected area, lumbar epidural injections can help reduce inflammation, alleviate pain, and improve the patient’s overall function and quality of life.

How Do Lumbar Epidural Injections Work?

Lumbar epidural injections work by delivering a mixture of local anesthetic and corticosteroid medication directly into the epidural space, the area surrounding the spinal cord and nerve roots in the lower back. This targeted approach aims to reduce inflammation and pain in the affected area.

The local anesthetic provides immediate, short-term relief by numbing the area, while the corticosteroid medication works to reduce inflammation and swelling over a longer period, typically several weeks to several months. The combination of these two medications can help break the cycle of pain and inflammation, allowing the body to heal and the patient to experience improved function and mobility.

Lumbar epidural injections are typically performed under fluoroscopic (X-ray) guidance to ensure accurate placement of the medication and to minimize the risk of complications.

What to Expect During a Lumbar Epidural Injection Procedure

Prior to the procedure, a healthcare provider will thoroughly evaluate the patient to determine if a lumbar epidural injection is the appropriate treatment. This may include a physical examination, review of medical history, and potentially diagnostic imaging, such as an MRI or CT scan.

On the day of the procedure, the patient will be positioned on an exam table, and the injection site will be thoroughly cleaned and sterilized. The healthcare provider will then administer a local anesthetic to numb the area before inserting a small needle into the epidural space. Once the needle is properly positioned, the medication will be slowly injected.

Patients may experience some discomfort or pressure during the procedure, but it is generally well-tolerated. The entire process typically takes 15-30 minutes, and patients can usually return home the same day.

After the injection, patients may experience temporary pain or numbness in the injection site or the affected area. Patients need to follow the healthcare provider’s instructions for post-procedure care, which may include rest, ice, and physical therapy.

Frequently Asked Questions About Lumbar Epidural Injections

  1. How effective are lumbar epidural injections? Lumbar epidural injections have been shown to be an effective treatment option for a variety of spinal-related conditions. Studies have reported that up to 75% of patients experience significant pain relief and improved function following the procedure.
  2. How many lumbar epidural injections can I receive? The number of injections a patient can receive depends on the individual’s response to the treatment and the underlying condition being treated. Generally, patients can receive up to three injections per year, with a minimum of four to six weeks between each injection.
  3. Are lumbar epidural injections safe? Lumbar epidural injections are generally considered safe when performed by a qualified healthcare provider. However, as with any medical procedure, there are some risks, such as infection, bleeding, or nerve damage. The healthcare provider will discuss the potential risks and benefits with the patient prior to the procedure.
  4. How long does the pain relief from a lumbar epidural injection last? The duration of pain relief can vary from patient to patient, but typically lasts several weeks to several months. Some patients may experience longer-lasting relief, while others may require additional injections to maintain their desired level of pain management.
  5. Are there any activity restrictions after a lumbar epidural injection? Patients are usually advised to rest for the first 24-48 hours after the procedure and avoid strenuous activity. The healthcare provider will provide specific instructions on any activity restrictions or limitations based on the individual’s condition and response to the treatment.
