This guide offers an educational, technical overview of pain management, spine & algology and the device technologies used in this field. A central technique is radiofrequency (RF) treatment, in which controlled energy is delivered through an electrode to thermally ablate or modulate nerves that transmit pain signals. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Chronic Pain Managed with Interventional Radiofrequency Techniques
Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment. Thermal RF creates a heat lesion to interrupt pain transmission, while pulsed RF applies energy in bursts intended to modulate the nerve without the same degree of thermal lesioning. A central technique is radiofrequency (RF) treatment, in which controlled energy is delivered through an electrode to thermally ablate or modulate nerves that transmit pain signals.
Core Technologies and Options
Radiofrequency Ablation for Back Pain. Radiofrequency ablation for back pain delivers controlled RF energy through an electrode to create a heat lesion on a pain-transmitting nerve. It is commonly directed at the medial branch nerves associated with the facet joints once these have been implicated in a patient's pain. Facet Joint Radiofrequency Ablation. Facet joint radiofrequency ablation targets the medial branch nerves that carry sensation from the small facet joints of the spine. Diagnostic blocks are often used beforehand to confirm that these nerves are the source of pain, as judged by the clinician. Genicular Nerve Ablation (Knee RFA). Genicular nerve ablation, or knee RFA, targets the sensory genicular nerves around the knee to address chronic knee pain in selected patients. It is sometimes considered for persistent pain, including after knee surgery, when other measures have not provided adequate relief. Nerve Ablation for Pain (Rhizotomy). Rhizotomy is a term used for the interruption of specific sensory nerves to reduce pain transmission, and RF is one way to achieve it. By creating a thermal lesion on the targeted nerve, the technique is intended to reduce the pain signals it carries. Pulsed and Thermal RF Modes. Thermal RF applies continuous energy to raise nerve tissue temperature and create a heat lesion, while pulsed RF delivers energy in bursts. Pulsed RF is intended to modulate the nerve with less thermal lesioning and is used in situations where a clinician judges it appropriate. Intraosseous RF Ablation for Spinal Tumors. Intraosseous radiofrequency ablation delivers RF energy within bone to treat certain painful spinal tumor lesions. It is a targeted technique intended to address tumor-related pain and local disease within the vertebral body, as determined by the treating team.
Comparing the Approaches
Radiofrequency ablation vs Steroid injections. Steroid injections deliver anti-inflammatory medication around a painful structure and may provide temporary relief in some patients. Diagnostic blocks are often used before RF to confirm the pain source, whereas injections may serve both diagnostic and therapeutic roles. Thermal RF vs Pulsed RF. Thermal RF creates a heat lesion by continuously raising nerve tissue temperature, while pulsed RF applies energy in bursts to modulate the nerve. Generators such as the INVAMED Peta platform support controlled delivery through temperature and impedance feedback in both approaches. Radiofrequency ablation vs Spinal cord stimulation. Radiofrequency ablation lesions or modulates specific pain-transmitting nerves and does not leave an implanted device behind. The two occupy different places in the pain management pathway and address pain through different mechanisms.

Key Considerations
- The literature commonly cites facet RF relief in the range of about 6 to 12 months, but individual duration varies and is not guaranteed.
- Manufacturer descriptions reflect device design intent rather than a guaranteed outcome for any individual.
- Because sensory nerves can regenerate, repeat treatment may be considered over time, based on the return of symptoms.
Frequently Asked Questions
What is the regulatory status of these RF devices?
Regulatory status such as European market authorization and manufacturing standards are stated in the product documentation and depend on local registration by market.
What feedback does the Peta RFA system provide?
INVAMED states the Peta RFA for Pain provides real-time feedback on temperature, impedance, and lesion size to support safe energy titration.
Can RF ablation be repeated if pain returns?
Because treated sensory nerves can regenerate, a repeat procedure may be considered in appropriate cases; the timing is an individualized clinical decision.
