Brief Answer:
To rule out cause for pain

Detailed Answer:
Hi, Thanks for using HCM.

I went through your query and understood your concerns.

A medial branch nerve block is a procedure in which an anesthetic is injected near small medial nerves connected to a specific joints in back bone that is vertebrae . Typically several levels of the spine are injected in one procedure.

If the patient experiences marked pain relief immediately after the injection, then the facet joint is determined to be the source of the patient's pain.

This procedure is basically for diagnosing condition, to find out cause for your pain. not treatment.if the patient has the appropriate duration of pain relief after the medial branch nerve block, then he or she may be a candidate for a subsequent procedure - called a medial branch radiofrequency neurotomy (or ablation) - for longer term pain relief.

Thus procedure is done on your back bone, vertebrae, especially lower bones.

Hope I answered your query. Feel free to ask further related query.

Wish you a good health.

Brief Answer:
Success rate only 50%

Detailed Answer:
Hi, thanks for using HCM.

In medial branch radiofrequency ablation procedure, a heat lesion is created on certain nerves with the goal of interrupting the pain signals to the brain, thus eliminating pain.

The term. radiofrequency ablation refer to a procedure that destroys the functionality of the nerve using radiofrequency energy.


Success rates vary, but typically about 30% to 50% of patients undergoing this procedure for low back pain will experience significant pain relief for as much as two years. Of the remaining low back pain patients, about 50% will get some pain relief for a shorter period.

Other complications are similar to other surgery like, allergic reaction to injection, injury to nearby nerves. which are very unlikely.
