Diagnostic Facet Injection / Medial Branch Block
A diagnostic injection that tests whether the small joints of the spine (facet joints) are the source of your neck or back pain.
What Is a Facet Injection or Medial Branch Block?
The facet joints are small joints at the back of the spine that help it bend and twist. When they are irritated or arthritic, they can cause neck or back pain. A medial branch block places a small amount of numbing medicine on the tiny nerves (medial branches) that carry pain signals from these joints. A facet joint injection places medicine directly into the joint. If your pain eases significantly after the block, the facet joints are a likely source, and radiofrequency ablation may be an option for longer relief.
Conditions It May Help
- Facet joint arthritis
- Axial (central) neck or low back pain that does not travel down the arm or leg
- Pain that worsens with twisting, bending backward or standing
- Whiplash-related neck pain
How It Is Done
The skin is numbed, and with fluoroscopy Dr. Rema guides thin needles to the target nerves or joints. The procedure usually takes about 15 to 30 minutes.
What to Expect
You will be asked to track your pain over the next several hours, often with a simple pain diary. Relief from the numbing medicine is usually temporary, and that is expected; this is mainly a test. Most people return to normal activity the next day.
Possible Side Effects and Risks
Temporary soreness at the injection sites or a brief increase in pain. Uncommon risks include infection, bleeding and nerve irritation. Dr. Rema will review your medical history and medications, including blood thinners, before your procedure.
