Lumbar Facet Block


A lumbar facet block is a procedure used to decrease inflammation in your spine. Medicines are injected at facet joints in your lower back. Facet joints are found at the back of each vertebrae.


Before your procedure:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
  • An IV is a small tube placed in your vein that is used to give you medicine or liquids.
  • Local anesthesia is a shot of medicine put into your skin. It is used to numb the area and dull the pain. You may also get medicine to keep you calm and relaxed. You may still feel pressure or pushing during the procedure.

During your procedure:

You will lie on your stomach, with your body slightly turned to the side. A pillow may be placed under your abdomen, or you may be asked to bend one or both knees. A needle will be inserted into the facet joint in your lower back. Your surgeon may use dye with an x-ray or CT to help guide the needle. He will inject medicines, such as steroids, to decrease inflammation. He will remove the needle and cover the injection area with a small bandage.

After your procedure:

You will be taken to a room to rest until you are fully awake. You will be monitored closely for any problems. Do not get out of bed until your healthcare provider says it is okay. You will then be able to go home or be taken to your hospital room.

  • Pain medicine may be given. Do not wait until the pain is severe before you ask for more medicine.
  • Antibiotics help prevent infection caused by bacteria.


You may bleed more than expected or get an infection. Nerves, blood vessels, or muscles may be damaged. You may have numbness in other areas. You may still have lower back or leg pain.
