Radiofrequency Ablation (rfa) in Gurgaon

Radiofrequency Ablation (RFA) is a minimally invasive medical procedure that uses controlled radiofrequency energy (heat) to target specific pain-transmitting nerves. By reducing the nerve’s ability to send pain signals, RFA can provide meaningful relief and improve functional activity—often without the need for major surgery.

RFA is typically performed under fluoroscopy (C-Arm) or ultrasound guidance for precision and safety.

RFA is classified based on how energy is delivered and the effect on nerve/tissue:

• Continuous high-frequency current

• Controlled thermal lesioning (typically 60–90°C)

• Used for longer-lasting pain relief (e.g., facet joint pain)
  Goal: Neurodestruction to stop pain signals

• Energy delivered in short bursts

• Temperature kept below ~42°C

• Does not destroy the nerve; modifies signaling
  Goal: Neuromodulation (pain control without nerve damage)

• Internally cooled probe tip

• Creates a larger lesion zone for broader pain generators
  Goal: Treat larger pain-generating areas with precision

• Uses two active electrodes

• Produces focused lesions between electrodes
  Goal: Higher precision in selected cases

The technique is chosen based on the diagnosis, target anatomy, and clinical goals.

RFA is used when pain arises from a clearly identifiable source and is often considered after diagnostic blocks confirm the pain generator.

• Lumbar facet joint pain (chronic low back pain)

• Cervical facet pain (neck pain)

• Sacroiliac joint pain

• Knee osteoarthritis pain (genicular nerve RFA)

• shoulder and hip joint pain

• Trigeminal neuralgia (selected cases)

• Occipital neuralgia

• Intercostal neuralgia

• Post-surgical nerve pain

• Hypogastric plexus pain syndromes (selected cases)

During the procedure:

1. The skin is numbed using local anesthetic

2. A thin needle/probe is placed near the target nerve under imaging guidance

3. Sensory/motor testing may be performed to confirm safe positioning

4. Controlled radiofrequency energy is delivered to reduce pain signaling

Procedure time: typically 30–60 minutes
Stay: usually day-care, go home the same day
Relief onset: often gradual over days to weeks

• Interrupts pain-carrying nerve signals

• Protein denaturation

• Neuromodulation (in pulsed RFA)

• Reduced chronic pain

• Improved mobility and joint tolerance

• Decreased muscle guarding/spasm

• Better ability to move, exercise, and rehabilitate

• Improved comfort in daily activities

Once pain reduces:

• Movement confidence improves

• Physiotherapy becomes easier and more effective

• Strength and functional capacity improve

• Mild soreness at the procedure site

• Local swelling

• Temporary numbness/tingling (in some cases)

When performed by trained specialists under strict sterile technique and image guidance, RFA is considered a safe and well-established procedure for chronic pain.

Common short-term effects:

• Mild soreness

• Local swelling

• Temporary numbness/tingling

Serious complications are uncommon in properly selected patients.

Relief can last 6–18 months, sometimes longer, depending on:

• The condition treated

• The nerve targeted

• Individual healing and nerve regeneration

Since nerves can regenerate, RFA may be repeated if pain returns and it’s clinically appropriate.

You may be suitable if:

• Pain has persisted > 3–6 months

• Conservative treatment (physiotherapy/medications) has not helped enough

• The pain source is confirmed—often via diagnostic nerve blocks

• Surgery is not indicated or you prefer a non-surgical route

A detailed clinical evaluation is essential before recommending RFA.

• Active local or systemic infection

• Uncontrolled bleeding disorder

• Unclear/uncertain pain diagnosis without confirmed pain source

• Inability to safely position or cooperate during the procedure

• Blood thinners (anticoagulants)

• Pregnancy (depends on target region and imaging needs)

• Uncontrolled diabetes or hypertension

• Implanted electrical devices (special precautions required)

In most cases:

• 1 session per target nerve/region is sufficient

Additional sessions may be needed if:

• Multiple pain areas are treated (often staged)

• Pain returns after months/years due to nerve regeneration

• Partial response after the first session (selected cases)

Most patients report it is more comfortable than expected:

During preparation

• Small pinch/sting from local anesthetic

During the procedure

• Mild pressure

• Brief warmth/buzzing sensation

• Occasional dull ache or twitching

After the procedure

• Mild soreness like a bruise

• Temporary stiffness

• Usually settles in a few days

Most people return to routine activity within 24–72 hours (as advised).

RFA and physiotherapy are not competing treatments—they are complementary.

• RFA reduces the pain barrier

• Physiotherapy restores movement, strength, and biomechanics

With structured physiotherapy after RFA:

• Strength improves

• Movement patterns normalize

• Recurrence risk reduces

• Long-term functional outcomes improve

This integration is often what turns pain relief into sustainable recovery.
