Commonly Asked Questions

  • What is a Rhizotomy Procedure?

    Rhizotomy, also known as radiofrequency ablation (RFA) or neurotomy, is a specialised minimally invasive medical procedure used to interrupt pain signals from targeted nerves. It involves using radiofrequency energy to create a controlled lesion on the nerve, which disrupts its ability to transmit pain signals to the brain.

    Rhizotomy is commonly performed to alleviate chronic pain especially when the pain is caused by conditions like arthritis or nerve impingement.

    Your doctor will discuss this procedure with you to determine your suitability. This will include an assessment of potential benefits and risks of the procedure.

  • Potential Risks and Complications

    While rhizotomy ablation is generally considered safe, there are potential risks and complications to be aware of, including:

    • Infection at the injection site
    • Bleeding or bruising
    • Nerve damage or irritation
    • Temporary or permanent sensory changes or numbness
    • Allergic reactions to anaesthesia or contrast agents (if used)
    • Rare instances of motor weakness or paralysis (extremely rare)
  • Before the Procedure
    • Please complete the relevant admission paperwork provided to you by your Pain Specialist.
    • Please cease any blood thinning medication as advised by your Pain Specialist.
    • Your admission time will be advised by the hospital staff the day prior to your procedure.
    • Your Anaesthetist will also contact you prior to the procedure for an assessment.
  • On the Day of Procedure
    • Please present to the hospital at the advised admission time.
    • You will meet your Pain Specialist and the Anaesthetist just before your procedure.
    • Your procedure will be performed using real-time X-ray or ultrasound guidance to precisely target the source of pain.
    • A thin needle with an electrode at the tip is inserted near the targeted nerves. Once the needle is correctly positioned, a radiofrequency current is delivered through the electrode. This creates a thermal lesion on the nerve, disrupting the pain signals.
    • Once completed, the needle is removed, and a small bandage is applied to the insertion site.
  • Post Procedure Care
    • You may experience some soreness or discomfort at the treatment site, which can typically be managed with over-the-counter pain medication. You may need to rest up to a week before resuming exercise. It is recommended that you continue with your physical therapy after this recovery period.
    • Pain relief following rhizotomy ablation can vary among individuals. Some patients experience immediate relief, while others may take up to 4 weeks to feel the full benefits. The duration of pain relief can also vary, ranging from months to years.
    • Once you had recovered you will be discharged from the hospital on the same day.
  • Follow up
    • Your Pain Specialist will schedule a follow up appointment 6 weeks after your procedure. At the appointment they will assess your progress, address any concerns, and determine the need for additional treatments or interventions.
    • Please do not hesitate to contact the practice if you have any concerns.
    • If the clinic is closed and you need more urgent medical advice, please present to the nearest Emergency Department.
