Interventional Pain Treatment: A Modern Approach to Chronic Pain Management
Interventional pain treatment has transformed the way clinicians manage chronic pain, particularly for patients who have not achieved meaningful relief from medication, physiotherapy, or lifestyle changes. Rather than simply masking symptoms, interventional techniques target the precise anatomical sources of pain, offering longer-lasting relief and improved quality of life. For patients with conditions such as facet joint arthropathy, trigeminal neuralgia, or chronic back and neck pain, these minimally invasive treatments can be life-changing.
Among the leading technologies enabling these procedures is the Diros Owl® Radiofrequency System, a high-precision platform designed specifically for radiofrequency (RF) lesioning and neuromodulation. Its accuracy, safety, and reliability make it a preferred option for consultants and pain specialists across the UK.

What Is Interventional Pain Treatment?
Interventional pain treatment refers to a group of minimally invasive procedures performed using imaging guidance—typically fluoroscopy, ultrasound, or CT—to diagnose, treat, and manage pain. These treatments aim to interrupt pain signals, reduce inflammation, and restore function by targeting nerves, joints, or soft tissues contributing to pain.
Common interventional methods include the following list:
Radiofrequency ablation (RFA)
Medial branch blocks
Epidural steroid injections
Sympathetic nerve blocks
Gasserian ganglion procedures
Pulsed RF neuromodulation
Trigger point injections
These procedures are often performed in an outpatient setting and allow patients to return to normal activity quickly.
Why Interventional Pain Treatment Matters
Chronic pain affects millions of individuals each year and is a leading cause of disability worldwide. Medication alone—particularly long-term opioid therapy—carries risks and often fails to provide sustainable relief. Interventional pain treatment offers an evidence-based alternative that can:
- Reduce reliance on medication
- Minimise systemic side effects
- Target the anatomical source of pain
- Provide relief lasting months or even years
- Improve mobility, sleep, and mental wellbeing
Studies have shown that interventional procedures, particularly radiofrequency-based techniques, can deliver significant reductions in pain intensity and improvements in function for a wide range of conditions (Nath et al., 2008) (De Andrés et al., 2016).
Radiofrequency Treatments: The Cornerstone of Interventional Pain Medicine
Radiofrequency (RF) procedures are among the most established and effective interventional treatments for chronic pain. RF energy uses controlled heat or electric fields to modulate nerve function, preventing the transmission of pain signals.
There are two main categories:
1. Thermal Radiofrequency Ablation
This method heats the targeted nerve to approximately 80–90°C to create a localised lesion. This disrupts the nerve’s ability to transmit pain. It is particularly effective for:
-
Facet joint pain
-
Sacroiliac joint pain
-
Occipital neuralgia
-
Trigeminal neuralgia
Thermal RFA has been shown to provide relief lasting 6–24 months in suitable patients (Cohen et al., 2020).
2. Pulsed Radiofrequency (PRF)
Rather than creating a destructive lesion, PRF delivers short bursts of RF energy at lower temperatures, modulating the nerve without significant heat damage. This makes it ideal for neuropathic conditions where preservation of nerve structure is essential.
PRF has demonstrated favourable outcomes in conditions such as radicular pain, peripheral neuropathies, and chronic shoulder pain (van Zundert et al., 2007).
The Role of the Diros Owl® System in Interventional Pain Treatment
The Diros Owl® Radiofrequency System plays a central role in modern interventional pain treatment, offering clinicians a precise, dependable, and highly adaptable platform for a wide range of radiofrequency procedures. As chronic pain continues to affect a growing number of people, the demand for safe, targeted, and minimally invasive treatment options has never been greater. Radiofrequency lesioning and neuromodulation are among the most effective solutions available, and the Diros Owl system has become a trusted choice for specialists who require both accuracy and consistency in their clinical practice.
Designed with the needs of pain consultants, anaesthetists, and neurosurgeons in mind, the Diros Owl system supports a comprehensive variety of procedures ranging from facet joint denervation to complex interventions such as Gasserian ganglion lesioning. Its advanced engineering, temperature-controlled lesioning, and reliable stimulation feedback give clinicians confidence when working near sensitive structures, while its flexible electrode and cannula configurations allow for tailored approaches based on the patient’s anatomy.
Whether used for thermal ablation or pulsed RF neuromodulation, the Diros Owl system provides the level of precision required to achieve predictable, high-quality outcomes. For clinics seeking a dependable and versatile RF platform, it remains one of the leading solutions available.

The Diros Owl® Radiofrequency System is widely used by pain consultants for its precision, flexibility, and safety profile. The system offers:
High-Accuracy Lesioning
The Diros Owl’s constant temperature monitoring and controlled lesion generation ensure predictable and reproducible outcomes—critical for sensitive areas such as the trigeminal ganglion.
Advanced Electrode and Cannula Options
Different electrode lengths, gauge sizes, and tip configurations allow clinicians to tailor procedures to the patient’s anatomy and condition.
Smooth Workflow With Real-Time Feedback
The system’s digital interface, impedance monitoring, and continuous sensory/motor stimulation help confirm accurate needle placement and reduce the risk of complications.
Versatility Across Procedures
The Diros Owl is commonly used for:
-
Facet joint denervation
-
Gasserian ganglion RF
-
Splanchnic nerve procedures
-
Dorsal root ganglion neuromodulation
-
Sympathetic blocks
Its reliability makes it a trusted choice in pain clinics, neurosurgical departments, and interventional theatres worldwide.
The Procedure: What Patients Can Expect
Most interventional pain procedures follow a similar structure:
1. Assessment and Diagnosis
A thorough medical history, physical examination, and imaging review help determine the most appropriate procedure.
2. Image-Guided Needle Placement
Fluoroscopy or ultrasound ensures needles are placed accurately at the target site. Proper placement is essential for both safety and efficacy.
3. Sensory and Motor Testing (RF Procedures)
Before delivering RF energy, clinicians use the system’s stimulation capabilities to confirm that the needle is positioned on the intended nerve.
4. Treatment Delivery
RF energy, medication, or a therapeutic agent (depending on the procedure) is delivered through the electrode or needle.
5. Rapid Recovery
Most patients go home the same day, with minimal downtime.
Conditions Commonly Treated With Interventional Pain Techniques
Interventional pain procedures can help with:
-
Chronic back and neck pain from facet degeneration or disc disease
-
Sciatica and radiculopathies
-
Osteoarthritis-related pain
-
Neuropathic pain conditions
-
CRPS (Complex Regional Pain Syndrome)
-
Post-surgical persistent pain
-
Shoulder, hip, and knee pain
-
Trigeminal neuralgia
For many of these conditions, radiofrequency lesioning offers longer-lasting relief compared with steroid injections or medication alone (Manchikanti et al., 2015).
Benefits of Interventional Pain Treatment
Interventional treatments offer several key advantages:
-
Minimally invasive with reduced recovery time
-
Targeted—treats the precise pain source
-
Long-lasting relief compared to injections alone
-
Reduced medication dependence
-
Improved mobility and daily functioning
-
Favourable safety profile when performed by trained professionals
When paired with rehabilitation, lifestyle adjustments, and ongoing clinical review, these treatments form a comprehensive and highly effective approach to chronic pain management.
