Medial Branch Block (MBB)

Medial Branch Blocks are typically recommended for individuals experiencing chronic back pain that has not responded well to conservative treatments such as physical therapy, medications, or lifestyle modifications. Ideal candidates are those whose pain is suspected to originate from the facet joints. The procedure is most commonly used for patients with arthritis-related neck, mid-back, or lower back pain. A thorough evaluation by your physician will determine if a Medial Branch Block is appropriate for your condition.

Medial Branch Blocks are generally safe, but as with any medical procedure, there are potential risks and side effects. Common side effects include temporary soreness or discomfort at the injection site, mild bruising, or a slight pain increase before relief. In rare cases, patients may experience an allergic reaction to the anesthetic or an infection at the injection site. Discussing these risks with your physician before the procedure ensures you are well-informed and prepared.

The relief from a Medial Branch Block is typically temporary, lasting only a few hours to a few days. The primary goal of the procedure is diagnostic—to determine if the facet joints are the source of your pain. If significant relief is achieved, your physician may recommend further treatment options, such as Radiofrequency Ablation (RFA), which can provide longer-lasting relief.

Medial Branch Blocks can be repeated, particularly if the initial block provides significant diagnostic information or temporary relief. However, they are usually performed as a precursor to more definitive treatments like Radiofrequency Ablation. Your physician will guide you on the appropriate timing and frequency of repeat procedures based on your case.

The Medial Branch Block procedure is generally well-tolerated by most patients. A local anesthetic is used to numb the area before the injection, which helps to minimize discomfort. You may feel a brief pinch or pressure as the needle is inserted, but the procedure is quick, typically taking only 5 to 10 minutes. Most patients report minimal pain during and after the procedure.

Medial Branch Blocks are primarily diagnostic, helping to pinpoint the exact source of back pain by temporarily blocking pain signals from the facet joints. This targeted approach allows for more accurate diagnosis than general pain relief methods like oral medications. If the block is effective, it may lead to treatments such as Radiofrequency Ablation, which can provide longer-lasting relief. Compared to more invasive surgical options, Medial Branch Blocks are minimally invasive and offer a quick recovery, making them an attractive option for patients seeking to avoid surgery.
