Radiofrequency Ablation

Radiofrequency Ablation in Denver Colorado

lumbar-radiofrequency-ablationFor patients with back and neck pain, radiofrequency ablation is a revolutionary procedure. This procedure usually is considered when other treatments have not been proven effective for chronic pain.


What is radiofrequency ablation?


Radiofrequency ablation is a procedure that uses a special type of needle emitting radio waves to painful nerves. This destroys the nerve’s ability to function. Other names for radiofrequency ablation is rhizotomy, radiofrequency neurotomy, and neurotomy.


What are the types of radiofrequency ablation?


The three main types of radiofrequency ablation (RFA) include:


  • Thermal/conventional RFA – A radiofrequency current is created that pools energy into the tissue. The electrical current converts to heat, which makes a small lesion on the nerve so it cannot transmit pain signals.


  • Pulsed RFA – With this procedure, the voltage is higher and is emitted in a pulsed manner, which allows energy to dissipate easily. This RFA technique leaves the nerve intact, and only affects the pain conducting nerve fibers.


  • Water-cooled RFA – Using an actively cooled, multi-channel electrode, this procedure allows temperature control while destroying the nerve.


What conditions are treated using radiofrequency ablation?


Conditions treated using RFA include:


  • Neck pain
  • Back pain
  • Spondylolysis
  • Knee pain
  • Sacroiliitis
  • Pelvic Pain
  • Trigeminal neuralgia
  • Headaches
  • Facial pain
  • Complex regional pain syndrome
  • Peripheral neuropathy
  • Pelvic pain


What can I expect with the consultation?


The consultation is required before the procedure. During this time, the doctor will decide if your pain is caused from facet (spinal) joint pain. The small nerves targeted with RFA are the medial branch of the spinal region. With RFA, the pain source is identified using a diagnostic block, which involves use of a local anesthetic to a suspicious area. If the diagnostic treatment works, the doctor will then schedule you for a radiofrequency ablation procedure.


How many treatments are needed?


One radiofrequency ablation treatment may work for most people, but for others, it takes more than one treatment. An ablation typically last for 8-24 months.


Is radiofrequency therapy right for me?


Radiofrequency therapy is a specific procedure that works by using mild electrical current to prevent nerves from sending pain signals. The doctor will take x-rays and other diagnostic scans first to assure that you have a condition that is treatable with the procedure.


What are the advantages of the radiofrequency ablation procedure?


RFA has many advantages. This procedure offers:


  • Immediate pain relief without a single incision
  • Little or no recovery time
  • Improved function and mobility
  • Decreased need for pain medications
  • Quicker return to work and all activities


How is the procedure done?


Before the RFA procedure, a nurse will place an IV catheter in your arm to administer pain medicines. After this, he will clean the back using an antiseptic solution and numb the skin and deeper tissues with an anesthetic. The procedure needle is inserted using fluoroscopy (real-time x-ray), and the electrical current is applied. After the needle is removed, the site is secured with a bandage.


Does radiofrequency ablation work?


There are many studies regarding radiofrequency ablation, which is used to treat facet joint syndrome and back pain. In a large stud where RFA was compared to sham treatment, patients reported more than 50% reduction in pain. Another study found that patients had significant pain relief and improved functional status for up to 12 months after RFA. Further studies for occipital neuralgia and headaches show that radiofrequency ablation is useful for pain relief at the 3-month follow-up.
