Chronic lower back pain can interfere with everything from walking to sleeping. At iOSS Medical, we specialize in advanced, non-surgical treatments and diagnostic procedures like lumbar medial branch blocks to help you move forward without constant discomfort.
Whether your pain is sharp, aching, or simply unrelenting, our goal is to identify the true source and provide targeted relief.
What Is a Lumbar Medial Branch Block?
A lumbar medial branch block is a minimally invasive procedure used to diagnose and relieve pain coming from the facet joints in your lower back.
Facet joints connect the vertebrae of your spine and play a key role in movement and stability. When they become inflamed or irritated—often due to arthritis, injury, or everyday wear and tear—they can cause persistent lower back pain.
During the procedure, a local anesthetic is carefully injected near the medial branch nerves, which transmit pain signals from the facet joints to the brain. By temporarily blocking these signals, we can determine whether the facet joints are the true source of your discomfort.
If the block provides noticeable pain relief, it strongly suggests that these joints are involved and helps guide future treatment.
The procedure is performed under X-ray guidance for precision, and most patients can return home shortly after.
When Is a Lumbar Medial Branch Block Necessary?
Your provider may recommend a medial branch block if you’re experiencing chronic lower back pain that has not improved with conservative care, and there’s reason to believe your facet joints may be involved.
Common indicators include:
- Pain that worsens with twisting or bending
- Stiffness in the lower back, especially in the morning
- Discomfort that radiates to the buttocks or upper thighs
- Limited response to physical therapy or medication
The medial branch block is often used as a diagnostic tool before moving forward with other procedures. It’s also useful for patients who prefer non-surgical options or are not candidates for spine surgery.
What Happens After a Lumbar Medial Branch Block?
If the block significantly reduces your pain, it’s a strong sign that your facet joints, as well as the medial branch nerves supplying them, are the source of your symptoms.
Based on your response, we’ll design a treatment plan that may include the following non-surgical options:
Facet Injections
Facet injections deliver a combination of anesthetic and anti-inflammatory medication directly into the facet joints. They help reduce inflammation and provide longer-lasting pain relief, often making it easier to participate in physical therapy or resume everyday activities.
Radiofrequency Ablation of the Facets
For patients who respond well to the medial branch block, radiofrequency ablation offers a more lasting solution. Using targeted heat, the procedure deactivates the medial branch nerves, preventing them from sending pain signals.
Relief can last several months or even longer, and the treatment can be safely repeated when needed.
Physical Therapy
Strengthening the muscles that support your spine can reduce pressure on the facet joints and improve your overall mobility. A personalized physical therapy program can be helpful to prevent future flare-ups.
Anti-Inflammatory Medications
Oral medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) may be used to reduce swelling and manage discomfort alongside other treatments.
Lifestyle and Postural Adjustments
Simple changes to how you move, sit, or sleep can make a big difference in how your spine feels day to day. Our team will help you identify stressors and habits that may be contributing to your pain.
