Medial Branch Block

WHAT IS A MEDIAL BRANCH BLOCK?
A medial branch block is an injection of a local anesthetic administered near the medial branch nerves to temporarily block the pain signal carried from the facet joints of the spine to the brain. It assists your doctor in diagnosing the cause of your back pain.
If a medial branch block is successful in confirming that the pain is originating from the facet joints, radiofrequency rhizotomy is suggested to provide longer pain relief. 

INDICATIONS AND CONTRAINDICATIONS OF MEDIAL BRANCH BLOCK

  • A medial branch block procedure is performed under fluoroscopy (X-ray) guidance to ensure the accurate placement of the needle and to avoid nerve injuries. 

  • You will be made to lie on your stomach on an X-ray table. The area of the skin to be injected is cleaned properly and a local anesthetic administered to numb the skin. A stinging or burning sensation may be felt for a few seconds. A small needle is then directed into the medial branch nerve area, under X-ray (fluoroscopy) guidance. Contrast dye is used to confirm the location of the needle over the medial branch nerves. A small mixture of the numbing agent and steroid medication is then slowly injected over the targeted nerves.

  • The whole procedure takes about 20-30 minutes and you can go home on the same day. 

WHAT TO EXPECT AFTER A MEDIAL BRANCH BLOCK
After the medial branch block, your pain may

  • Be relieved for a few hours 

  • Be relieved for a few days 

  • Not reduce at all

If the pain is relieved after the medial branch block, it indicates that the origin of the pain is the medial branch nerve supplying the facet joint.
Based on the amount of pain relief observed during the first 6-12 hours after the injection, you may be considered suitable for a radiofrequency neurotomy procedure to relieve the pain for a longer period. 
In radiofrequency neurotomy, an electrical current is passed through a needle at the selected medial branch nerve causing pain to interrupt the pain signals. 


POST-PROCEDURAL CARE FOLLOWING A MEDIAL BRANCH BLOCK

  • You should arrange for someone to drive you home after the procedure. 

  • You may continue your routine prescribed medications after a gap of 4-6 hours following the procedure to avoid incorrect assessment of diagnostic results related to pain relief.

  • You may experience localized pain at the injection site in the first 2-3 days, for which ice packs can be applied to ease the discomfort.

  • You can return to your regular activities, a day after the procedure.

  • In cases where improvement in the pain is seen, you are advised to perform moderate activities, with regular exercises.
