Ultrasound-guided or scopic facet nerve block is a technique used to treat chronic back pain, which usually originates in the facet joints.
These joints, which are located between the vertebrae, allow movement of the spine.
In cases of inflammation or degeneration, they can generate intense pain in the lower back, cervical or thoracic area.
At Clínica San Román, this procedure is an effective option for those who have not found relief with other conservative treatments.
What is Facet Nerve Block?
Facet block involves injecting a local anesthetic and, in some cases, corticosteroids near the nerves surrounding the facet joints of the spine.
The goal of this technique is to block pain signals transmitted to the brain from the affected joints, providing significant relief.
This procedure is performed under ultrasound or scopic (X-ray) guidance, which allows the specialist to visualize in real time the structure of the spine in order to administer the injection accurately.
Indications for Facet Nerve Blocks
Facet nerve block is an ideal option for treating chronic back pain related to facet joints.
Common indications include:
- Chronic facet pain: Pain originating in the facet joints of the spine, usually due to degeneration or inflammation.
- Spondylosis (osteoarthritis of the spine): Degeneration of the vertebrae that causes pain and stiffness in the back.
- Low back pain: Pain in the lower back, especially in patients who have not found relief with other conservative treatments.
- Chronic cervical or thoracic pain: Pain in the upper or mid back, which may be related to facet injuries.
How Does the Facet Nerve Block Work?
Facet nerve block is a minimally invasive procedure performed by injecting a local anesthetic, sometimes combined with a corticosteroid, around the affected facet joints.
The use of ultrasound or scopy during the procedure ensures that the physician can administer the injection with the utmost precision.
Ultrasound: Uses ultrasound to visualize the internal structures of the back and guide the needle to the injection site.
Scopic (X-ray): Employs real-time X-ray imaging to precisely guide the injection into the facet joints.
Once the anesthetic is administered, pain signals from the facet joints to the brain are temporarily blocked, providing fast and lasting relief.
Benefits of Facet Nerve Block
Ultrasound-guided or scopic facet nerve block has numerous benefits for patients with chronic back pain:
- Rapid pain relief: Many patients experience a reduction in pain immediately after the procedure.
- Targeted and precise treatment: The use of ultrasound or scopy allows the specialist to administer the treatment with great accuracy, improving the effectiveness of the procedure.
- Improved mobility: By relieving pain, patients can regain the ability to perform daily activities without restrictions.
- Non-surgical alternative: It is a less invasive option than spine surgery, with fewer complications and faster recovery times.
- Reduced use of analgesics: Prolonged pain relief can reduce the need for pain medications, minimizing the side effects associated with their prolonged use.
Procedure and Recovery
The facet nerve block is an outpatient procedure that usually lasts 20 to 30 minutes.
Local anesthesia is administered to the area to avoid discomfort during the procedure.
Using ultrasound or scopy, the specialist locates the affected facet joints and performs the injection.
After the procedure, most patients can resume normal activities within a few hours, although it is advisable to avoid strenuous physical exertion for the first 24 hours.
Pain relief usually lasts from several weeks to months, depending on the underlying cause of the pain and the patient’s response to treatment.
In some cases, the procedure may need to be repeated if pain recurs over time.
In addition, facet nerve block may be combined with other treatments, such as physical therapy or strengthening exercises, to improve long-term results.
When to Consider Facet Nerve Block?
The facet nerve block is an effective option for patients who have tried other treatments without success, such as oral medications, physical therapy or more general blocks.
It is particularly useful for patients experiencing chronic back pain due to facet joint problems, such as spondylosis or joint wear and tear.
At Clinica San Roman, our pain specialists evaluate each case on a case-by-case basis to determine if a facet nerve block is the appropriate treatment.
This procedure can also be part of a comprehensive approach that includes other treatments to maximize pain relief.
Conclusion
Ultrasound-guided or scopic facet nerve block is an effective and minimally invasive option for treating chronic back pain related to the facet joints.
At Clinica San Roman’s Pain Management Unit, our specialists use advanced technology and a personalized approach to ensure maximum pain relief for each patient.
