Is a Medial Branch Block Right for Your Back Pain?
In a minimally invasive medial branch block, a small amount of local anesthetic, with or without a corticosteroid, is injected near the spine's small nerves near the facet joints that carry pain signals to the brain. The injection blocks medial branch nerve pain signals to relieve targeted pain. Medial branch block and other invasive procedures can help doctors figure out if a facet joint is causing back pain. Using fluoroscopy, an anesthetic is given near small medial nerves that are linked to a facet joint. If the patient's pain disappears immediately after injection, the facet joint is the cause. For long-term pain relief, a medial branch radiofrequency ablation may be considered. Lumbar medial branch block is an invasive procedure that is used to diagnose and treat pain originating from the facet joints in the lower back. There are two middle branch nerves that run from the spine to the brain in each facet joint. Injecting medication into the fibro-osseous canal around these nerves blocks pain signals by surrounding the nerve with the drug. Patients should have two diagnostic medial branch block because one block can cause false-positive (placebo) responses. To allow the first block's effects to fade, the second injection should be done 2-3 weeks later. Cervical medial branch block is a procedure to diagnose and treat neck pain. Diagnostic medial branch blocks have been shown in more than one study to ease spine pain. Studies show that after a good diagnostic medial branch block, more than half of patients feel 80% less pain. Two separate medial branch blocks that prove facet joint pain at the same spinal level have a 60% chance of giving significant and long-lasting pain relief with RFA. Studies show that therapeutic medial branch block that combine anesthetic and corticosteroid do not relieve pain better than placebo. Medial branch block injection technique is conducted twice, typically 1-2 weeks apart, to mitigate the danger of a “false positive” (i.e., the injection seems effective but is only a placebo effect) or a “false negative” (i.e., the injection appears ineffective but is truly effective). The occurrence of a "false positive" or "false negative" result is significantly diminished if both injections are effective. If you have back or neck pain on both sides, these injections must be done on the most symptomatic side first. Again, this reduces block results misinterpretation. If you have neck or back pain, your pain specialist near me may recommend painkillers, exercise, and physiotherapy. In case these don't work and your doctor suspects facet joint pain, they may recommend a medial branch block. Most of the time, facet joint pain is caused by inflammation and wear and tear from osteoarthritis. After giving you a shot, a pain doctor in your area will be able to see where the pain is coming from. If the shot helps, the pain must be coming from that facet joint. How long pain relief lasts varies for each person. Some only have hours or days. Others feel pain relief for weeks at a time. You may be given radiofrequency denervation if a middle branch block doesn't help. Nerves that cause back or neck pain are turned off by radiofrequency waves. Depending on the person, the medicine may help with pain for six to two years. A lot of people can't get RF denervation. People who have a pacemaker or an artificial cardioverter defibrillator should stay away from it. Your doctor of pain clinic in Plano may suggest getting shots into your facet joints. Like medial branch blocks, facet joint shots have a small amount of steroid and a local anesthetic in them. The injection is into your facet joint. The goal is joint inflammation reduction. It can relieve pain for weeks, months, or years. Besides exercise, you may need repeated facet joint injections. A pain specialist will perform a medial branch block. You must lie on your front for a lower back injection and on your side for a neck injection. They may sedate you to relax. When you're ready, they'll clean your skin and inject a local anesthetic to make the procedure painless. The local anesthetic may sting briefly. X-rays will help your pain specialist locate the right spot on your back or neck. To locate the needle, they may inject a contrast medium as a dye. The pain physicians in Dallas injects after placing the needle. The facet joint nerves receive local anesthetic. Just a few minutes to inject. Even with X-rays, the procedure should take 20 minutes. The procedure is followed by recovery. Pain management in Dallas will briefly monitor you before you leave. They may initially ask you to lie flat. Your blood pressure or pulse will be checked. Several hours after the procedure, you can go home. You'll need a ride home since you can't drive. Following sedation, it is advisable to have someone accompany you during the initial night post-procedure.What Do Medial Branch Blocks Look Like?
