Preparation & Risk of Radiofrequency Ablation, Southlake, TX is a minimally invasive non-surgical procedure used to destroy the nerve fibers that carry pain signals to the brain. It is a procedure used to create a lasting relief for patients who are suffering from chronic pains in the neck, lower back, and arthritic joints.

Risk of Radiofrequency Ablation

The procedure entails using radiofrequency waves or heat to stop or reduce the transmission of pains to the brain. The radiofrequency waves burn (ablate) the nerve that is responsible for the transmission of pain signals to the brain. This prevents the transmission of pain from getting to your brain; hence you don’t feel pain anymore.

How nerves send pain signals to the brain

Preparation & Risk of Radiofrequency Ablation, Southlake, TXIt is the facet joints that allow your spine to twist from side to side and also allow you to move forward and backward. The facet joints are protected by a capsule of soft tissue. A layer of slick white cartilage covers the joint and helps the joint to glide easily whenever you feel like moving or bending.

The cartilage can wear thin or get damaged over time. When this occurs, the joints may become enlarged and spurs of bone may grow around or on the joint. These growths cause pain, swelling in the joints or arthritis.

Nerves from the spinal cord pass through the facet joints and extend into the other parts of the body which controls the activities in the body, movement and transmit sensations. The nerves serving the facet joints are called the medial branches. They also carry pain signals to the spinal cord and transmit to the brain.

When you feel pain in your joints, it is a warning sign that means that your joint is irritated, it has become enlarged or there are some irregular growths on/around your joint.

How to prepare for radiofrequency ablation

How to prepare for radiofrequency ablation

Before undergoing the procedure, you will be asked some questions about your health and any medications you are taking currently. Your doctor will review your medical history and plan the best location where the ablation will be done.

If you have any allergies, you need to let the doctor know and if there is anything you want to know, ask your doctor. If you are currently taking aspirin or blood-thinning medication, you will need to stop taking them for at least 11 days before the procedure.

You should not eat any food or drink any liquid for at least 6 hours before the procedure. Arrange for someone to drive you back home.

How the procedure is done

You will be asked to lie down on your stomach on a table. You will be given a local anesthetic at the area where the needle will be injected. The local anesthetic helps to numb the area to reduce discomfort during the procedure.

You will need to be awake during the procedure so you can let the doctor know how you are feeling at any given time.

The doctor will then direct a thin hollow needle into the area where the pain is felt using a fluoroscope. Your doctor uses the fluoroscope to see the direction of the needle inside your body to ensure that the needle goes in the right location. Your doctor will also inject contrast dye into the area so that he/she can see the area more clearly.

When the needle is in the right position, you will be given a numbing medication. A tiny electrode is inserted inside the needle and radiofrequency waves are passed through the needle. A small and precise burn is created by the radiofrequency wave. This destroys nerve tissue that is responsible for transmission of pain and stops the pain transmission. The pain is successfully stopped from transmitting to the brain, hence you won’t feel any more pain.

Multiple nerves can be burnt at the same time. It takes about 30-45 minutes for the procedure to be completed.

After the procedure

What to expect
