Lower back pain is one of the most common complaints among adults, affecting millions of people worldwide. Chronic back pain can be debilitating, impacting daily activities, work performance, and overall quality of life. Fortunately, advancements in pain management have introduced minimally invasive procedures that provide lasting relief without major surgery. One such innovation is nerve ablation.
For those living with lower back pain, it’s crucial to learn more about how ablation for nerve pain works for the lower back, what to expect from the procedure, and who may benefit from this approach.
Understanding Lower Back Pain and Its Causes
First, it’s helpful to understand why lower back pain occurs. The lower back, or lumbar region, is a complex structure comprising bones, discs, muscles, ligaments, and nerves.
Common causes of chronic lower back pain include:
- Arthritis: Chronic lower back pain can result from inflammation and degeneration of the joints in the spine, such as osteoarthritis. This process often leads to stiffness, swelling, and gradual deterioration of the protective cartilage, causing persistent discomfort.
- Degenerative Disc Disease: DDD occurs when the intervertebral discs lose their flexibility, elasticity, and shock-absorbing capabilities due to aging or injury. The breakdown of these discs can cause pain, instability, and sometimes nerve irritation in the lower back.
- Herniated Discs: A herniated disc happens when the soft inner material of a spinal disc pushes through a tear in the outer layer. This can compress nearby nerves, resulting in chronic pain, numbness, or weakness in the lower back and legs.
- Muscle or Ligament Strain: Repeated heavy lifting, sudden awkward movements, or poor posture can strain the muscles and ligaments in the lower back. Over time, this strain can lead to chronic inflammation and persistent pain.
- Spinal Stenosis: Spinal stenosis is the narrowing of the spaces within the spine, which can put pressure on the spinal cord and nerves. This nerve compression often leads to chronic pain, tingling, or weakness in the lower back and legs.
- Spondylolisthesis: Spondylolisthesis occurs when a vertebra slips out of place onto the bone below it. This misalignment can irritate spinal nerves, resulting in ongoing lower back pain and reduced mobility.
When conservative treatments like physical therapy, medications, and injections fall short, nerve ablation offers an alternative for those seeking relief.
What Is Nerve Ablation?
Nerve ablation is a minimally invasive medical procedure designed to reduce or eliminate pain by disrupting the function of specific nerves that transmit pain signals from the back to the brain. The process involves using heat, cold, or chemicals to intentionally damage or “ablate” the targeted nerves, thereby interrupting the pain pathway. There are several variations of nerve ablation, but the most common for lower back pain is radiofrequency ablation.
Pain signals from the lower back travel through specific nerves to the spinal cord and then to the brain, where they are perceived as pain. By selectively ablating these nerves, the communication pathway is interrupted, reducing or eliminating the sensation of pain.
It’s important to note that ablation for nerve pain does not treat the underlying cause of pain, such as arthritis or disc degeneration. Instead, it manages the symptom of pain by blocking its transmission.
The Nerve Ablation Procedure in Lower Back: Step-By-Step
The radiofrequency ablation process includes:
Evaluation and Planning
First, your pain specialist will perform a thorough evaluation, which may include physical exams, imaging studies like MRI or CT scans, and diagnostic nerve blocks. Diagnostic blocks involve injecting a local anesthetic near the suspected nerves to determine if pain relief occurs. A positive response helps pinpoint the nerves responsible for the pain.
Preparing for the Procedure
Ablation for nerve pain is typically an outpatient procedure. You’ll be asked to avoid eating or drinking for several hours beforehand. You may change into a gown, and an intravenous (IV) line might be placed to administer medication for relaxation or mild sedation.
Local Anesthesia and Positioning
You’ll lie face down on a procedure table. The skin over the lower back is cleaned and sterilized. A local anesthetic is injected to numb the area, ensuring you remain comfortable throughout the procedure.
Needle Placement Using Imaging Guidance
Using fluoroscopy, which is a real-time X-ray, or ultrasound, the doctor carefully inserts a thin, specialized needle into the target area near the nerves transmitting pain. Precise placement is critical to the success of the ablation nerve procedure.
Testing and Stimulation
Before ablation, a small electrical current may be passed through the needle to confirm correct nerve targeting. You may feel a tingling sensation or mild discomfort, which helps the physician verify the needle’s location.
Ablation of Nerves in Back
Once the needle is in the right position, the ablation of nerves in the back begins. For radiofrequency ablation, a probe is inserted through the needle, and radiofrequency energy heats the nerve tissue for 60–90 seconds. This heat disrupts the nerve’s ability to send pain signals. Multiple nerves can be treated during the same session if necessary.
Completion and Recovery
After the ablation for nerve pain, the needles are removed. A small bandage is applied, and you’ll be monitored for a short period before being discharged. Most people can walk out of the clinic and resume normal activities within a day or two.
Who Is a Good Candidate for Nerve Ablation?
A good candidate for nerve ablation is someone who has had chronic lower back pain for several months or longer, especially when other treatments such as physical therapy, medications, or injections have not provided enough relief.
People who experience significant pain relief after a diagnostic nerve block, which is a test injection that numbs the suspected nerve, are more likely to benefit from nerve ablation. This procedure is also a suitable option for individuals who want to avoid major back surgery due to reasons like age, health concerns, or personal preference.
Often, candidates have pain caused by conditions such as arthritis in the spine, degenerative disc disease, or nerve irritation, but do not have serious spinal instability. Nerve ablation is minimally invasive, offers a short recovery period, and can help people reduce their reliance on pain medications.
A back pain specialist can review your medical history and test results to determine if nerve ablation is an appropriate treatment for you.
What Is BVN Ablation?
While traditional nerve ablation targets the medial branch nerves, a newer approach called basivertebral nerve (BVN) ablation is gaining attention for specific types of chronic lower back pain, particularly pain linked to vertebral endplates, which is the interface between the disc and the vertebral body.
BVN ablation involves targeting the basivertebral nerve, which carries pain signals from the vertebral endplates. The procedure is similar to traditional radiofrequency ablation but focuses on a different nerve pathway. Early studies have shown promising results, especially for patients with chronic vertebrogenic lower back pain who haven’t responded to other treatments.
