Radiofrequency Ablation (Rhizotomy)
Long-lasting pain relief through precise nerve disruption
About Radiofrequency Ablation
Radiofrequency Ablation (RFA), also known as Rhizotomy, is an innovative minimally invasive procedure that uses heat generated by high frequency alternating current to target specific nerve fibers. This controlled heat disrupts the nerve's ability to transmit pain signals to the brain, providing significant and longer-lasting relief compared to injections. Dr. Hemani performs this procedure with advanced imaging guidance to ensure precise targeting of the pain-generating nerves while preserving surrounding healthy tissue.
Long-lasting Relief
Typically provides 6-12 months of pain reduction
Quick Procedure
Usually completed in 30-60 minutes as an outpatient
Targeted Approach
Precisely targets specific pain-generating nerves
Who Can Benefit
Radiofrequency ablation is particularly beneficial for patients with:
- Chronic pain not responding to conservative treatments like physical therapy or medication
- Positive response to diagnostic nerve blocks, confirming the pain source
- Pain originating from specific nerves that can be safely targeted
- Patients seeking longer-lasting relief than injections can provide
- Those looking to reduce reliance on pain medications
Dr. Hemani typically recommends diagnostic nerve blocks before radiofrequency ablation to confirm that targeting specific nerves will provide relief for your particular condition.
Types of Radiofrequency Ablation
Dr. Hemani offers several specialized types of radiofrequency ablation procedures, each designed for specific conditions and anatomical areas:
Medial Branch Radiofrequency Ablation
Targets the medial branch nerves that supply the facet joints of the spine. This is the most common type of RFA and is highly effective for facet joint pain in the neck or back.
Sacroiliac Joint Radiofrequency Ablation
Targets the nerves supplying the sacroiliac joint, providing relief for chronic SI joint pain that hasn't responded to other treatments.
Genicular Nerve Radiofrequency Ablation
Targets the genicular nerves around the knee joint, offering relief for chronic knee pain, particularly from osteoarthritis.
Pulsed Radiofrequency
A modified technique that delivers short bursts of radiofrequency energy rather than continuous heat. This approach is sometimes used for sensitive areas or specific types of nerve pain.
Cooled Radiofrequency Ablation
Uses internally cooled radiofrequency probes to create larger lesions, potentially increasing effectiveness for certain conditions like sacroiliac joint pain.
Peripheral Nerve Radiofrequency Ablation
Targets specific peripheral nerves outside the spine that are causing pain, such as occipital nerves for certain types of headaches.
