Radiofrequency ablation
Relief Needed
Radiofrequency ablation is a modern technique used to treat chronic spinal pain, especially when associated with facet joint wear, herniated discs, or nerve compression that does not respond to conservative therapies.
During the procedure, the doctor inserts a very thin needle, guided by imaging methods such as fluoroscopy or CT scan, until it is near the nerve responsible for the pain. The tip of this needle emits radiofrequency waves that produce controlled heat (usually between 80 and 90 degrees Celsius), creating a precise thermal lesion. This lesion temporarily blocks the nerve's ability to transmit pain signals to the brain.
The procedure is quick (20–40 minutes), performed under local anesthesia and light sedation, without the need for hospitalization. The main benefit is the significant reduction in pain without altering the anatomy of the spine, allowing the patient to maintain their daily routine with fewer limitations.
It is indicated for patients with persistent lower back or neck pain for more than 3 months who have already tried physiotherapy, medication, and other therapies without satisfactory results. It is also recommended for people who cannot or do not wish to undergo surgery.
First 1–3 days: There may be mild pain or a burning sensation in the treated area; this is considered normal. The patient should rest and avoid strenuous physical activity.
Weeks 1–2: Onset of pain relief. Some patients feel an immediate difference, but in many the effect appears gradually. Gentle physiotherapy may be recommended.
Weeks 3–6: Most patients are already experiencing consistent pain relief and are able to perform daily activities more easily. Core strengthening and postural correction exercises are introduced.
Following months: The effect can last between 6 months and 2 years, depending on nerve regeneration and patient care. The procedure can be repeated if necessary.
Is it a painful procedure?
No, it's done with local anesthesia and sedation. There may only be slight discomfort at the puncture site.
How long does the effect last?
It can last from 6 months to 2 years, depending on the case.
Do I need to be hospitalized?
No, it's outpatient. The patient is discharged on the same day.
Are there risks?
Rare, but transient pain, numbness, or local infection may occur.
Can I go back to work soon?
Typically within 24 to 48 hours, depending on individual recovery.
