Medial Branch Block (MBB)
At MVM Health, we use Medial Branch Blocks as a precise tool to both diagnose and relieve facet joint pain.
What Is a "Medial Branch Block"?
At MVM Health, a Medial Branch Block (also known as a Facet Block) is a precise diagnostic injection used to determine if your back pain is coming from your facet joints. These are small joints that connect the vertebrae along your spine. When they become inflamed or arthritic, they can cause localized pain that doesn’t travel down your legs. This procedure is the most effective way for our specialists to confirm the exact source of your discomfort and guide your treatment plan.
Understanding Your Facet Joints
and How Medial Branch Blocks Help
Your spine is supported by small, stabilizing joints called facet joints, which are located on the back of your spine and connect your vertebrae. These joints are essential for your mobility, providing the stability and flexibility needed to bend and twist smoothly. However, just like any other joint in your body, the facet joints can be affected by conditions like arthritis, injury, or natural wear-and-tear. When these joints become inflamed or damaged, they can cause a focused, aching pain in your back that can significantly interfere with your daily activities.
At MVM Health, we use a Medial Branch Block (MBB) as a precise diagnostic tool to determine if the facet joints are the source of your pain. The procedure involves injecting a small amount of local anesthetic near the medial branch nerves—the specific nerves that transmit pain signals from the facet joints to your brain.
What Is The Medial Branch Block Procedure?
The process begins with the patient lying face down. The skin is first sterilized with an antiseptic solution, and a local anesthetic is applied to numb the area, ensuring patient comfort. Using fluoroscopic (X-ray) guidance for absolute precision, a thin needle is carefully placed near the targeted medial branch nerves. A small amount of anesthetic is then administered around each nerve, which temporarily interrupts pain signals to help pinpoint the origin of the discomfort. The procedure is swift, typically taking only 5 to 10 minutes, and many patients experience immediate relief.
If the block is effective, it serves as a clear indicator that the patient may be a strong candidate for Radiofrequency Ablation (RFA), a procedure designed for longer-term pain management.
When a Medial Branch Block confirms that the facet joints are the pain generator, the next step may be an RFA. This advanced, minimally invasive procedure uses controlled heat to disrupt pain signals from the affected nerves for a more durable period. It is an effective option for providing sustained relief for those experiencing arthritis-related pain in the neck, mid-back, or lower back.
Pre-Procedure and Post-Procedure Instructions
PRE-PROCEDURE
Arrange Transportation: For your safety, you must have a responsible adult drive you home after the procedure. Driving is not recommended on the day of your injection.
Discuss Medications: Inform your doctor of all medications you are currently taking. It is especially important to discuss any blood thinners (e.g., Warfarin, Plavix, Aspirin), as they may need to be temporarily stopped.
POST-PROCEDURE
Rest: Avoid strenuous activities and heavy lifting for at least 24 to 48 hours following the procedure to allow the area to rest.
Apply Ice: If you experience minor swelling or discomfort at the injection site, you may apply an ice pack for 15-20 minutes at a time.
Avoid Submersion: Do not submerge the treated area in water. Avoid baths, swimming pools, hot tubs, or saunas for the first 24 to 48 hours. Taking a shower is permissible.
Monitor for Complications: Watch for any signs of infection, such as significant swelling, increasing redness, warmth, or discharge from the injection site. Please inform our clinic immediately if these or any other adverse reactions occur.
Schedule a Follow-Up: A follow-up appointment is essential to assess the diagnostic results of your block. Please schedule this with our team to discuss your progress and determine the next steps in your treatment plan.

Medial Branch Blocks
FAQ
What is a medial branch block?
A medial branch block is a minimally invasive diagnostic injection that delivers a small amount of local anesthetic near the medial branch nerves, the nerves responsible for transmitting pain signals from the facet joints to the brain. It helps determine whether your back or neck pain is originating from the facet joints.
What conditions is a medial branch block used to diagnose or treat?
A medial branch block is primarily used to identify facet joint pain caused by arthritis, injury, or age-related wear and tear. It is commonly used for chronic neck pain, mid-back pain, and lower back pain that hasn’t responded to conservative treatments like physical therapy or medication.
How is the medial branch block procedure performed?
You will lie face down while the skin is cleaned and numbed with a local anesthetic. Using fluoroscopic (X-ray) guidance, a thin needle is carefully directed near the targeted medial branch nerves. A small amount of anesthetic is then injected to temporarily block pain signals. The procedure typically takes only 5 to 10 minutes.
Is a medial branch block painful?
The procedure is generally very well-tolerated. A local anesthetic is applied beforehand to minimize discomfort. You may feel a brief pressure sensation or mild pinch when the needle is placed, but most patients report little to no pain during the injection itself.
How long does relief from a medial branch block last?
Relief from a medial branch block is temporary by design, typically lasting from a few hours to a few days. Its main purpose is diagnostic, to confirm whether the facet joints are the source of your pain. Significant relief indicates that you may be a good candidate for longer-lasting treatment.
Am I a candidate for a medial branch block?
You may be a candidate if you have ongoing back or neck pain that hasn’t improved with conservative treatments, and your physician suspects the facet joints may be the pain source. A thorough evaluation is needed to determine whether this procedure is the right diagnostic step for your situation.
What should I do to prepare for the procedure?
You should arrange for a responsible adult to drive you home, as driving is not recommended on the day of the procedure. You should also inform your doctor about all current medications, especially blood thinners such as Warfarin, Plavix, or Aspirin, as these may need to be paused temporarily before the injection.
What can I expect after a medial branch block?
After the procedure, you should rest and avoid strenuous activity or heavy lifting for 24 to 48 hours. You may apply an ice pack to the injection site if there is minor swelling or soreness. Avoid submerging the area in water, including baths, pools, hot tubs, and saunas – for the first 24 to 48 hours. Showers are permitted.
What are the risks or side effects?
A medial branch block is considered a very safe procedure. The most common side effects are mild and temporary, such as soreness or bruising at the injection site, or a brief flare-up of pain before relief sets in. Rare risks include infection or an allergic reaction to the anesthetic. Your physician will review all potential risks with you beforehand.
How many times can a medial branch block be repeated?
The procedure can be repeated if needed for diagnostic clarity, but it is not intended as an ongoing or stand-alone treatment. It is most often used as a one-time step to confirm the pain source before moving on to a more lasting solution. Your physician will advise on appropriate timing and next steps based on your response.
What happens if the medial branch block is effective?
If you experience significant pain relief following the block, it confirms that the facet joints are the source of your pain. This positive result typically means you may be a strong candidate for Radiofrequency Ablation (RFA), a procedure that uses controlled heat to disrupt pain signals for longer-term relief.
What is the difference between a medial branch block and radiofrequency ablation?
A medial branch block uses a temporary anesthetic to confirm whether the facet joints are causing your pain, it is primarily a diagnostic tool with short-term relief. Radiofrequency Ablation (RFA), on the other hand, uses heat energy to interrupt nerve pain signals for a more durable, longer-lasting period. The block is typically the first step before considering RFA.
