Intracept Procedure

The Intracept Procedure is a minimally invasive treatment for chronic low back pain that comes from a specific type of spinal change. It involves using radiofrequency energy to disable a nerve inside the vertebrae, which can reduce pain signals. This procedure is typically considered when other treatments have not provided enough relief.

What is Intracept Procedure?

The Intracept Procedure is a minimally invasive medical treatment designed to relieve chronic low back pain that originates from specific changes in the spine. It targets the basivertebral nerve, a sensory nerve located within the vertebrae (bones of the spine), using radiofrequency energy to stop it from sending pain signals.

This procedure is specifically for individuals experiencing chronic low back pain that has lasted for at least six months and has not improved with other treatments. The pain must also be linked to certain changes in the vertebral endplates, known as Modic changes, which can be seen on an MRI scan. During the Intracept Procedure, a small probe is inserted into the affected vertebra. This probe delivers radiofrequency energy, which creates a small burn (ablation) to disable the basivertebral nerve. By disrupting this nerve, the procedure aims to reduce the pain signals sent from the spine to the brain. The Intracept Procedure is performed by trained clinicians, often pain management specialists or spine surgeons. It is an outpatient procedure, meaning you can usually go home the same day. The goal is to provide lasting relief from chronic low back pain, improving your quality of life.

Why it's done

The Intracept Procedure is performed to treat chronic low back pain that has not responded to conservative treatments and is specifically linked to changes in the vertebral endplates. These changes, called Modic changes, are thought to be a source of pain signals, and the procedure aims to interrupt these signals.

Chronic low back pain can significantly impact daily life, making simple activities difficult. When traditional treatments like physical therapy, medications, and injections fail to provide adequate relief, your doctor might consider other options. The Intracept Procedure targets a specific type of back pain. Research suggests that the basivertebral nerve, located in the vertebrae, plays a role in transmitting pain signals from damaged or inflamed vertebral endplates (the top and bottom surfaces of the vertebral body). These endplate changes, known as Modic changes, are visible on an MRI and are often associated with chronic low back pain. By ablating (disabling) the basivertebral nerve, the procedure aims to stop these specific pain signals from reaching the brain. This can lead to a significant reduction in pain for carefully selected patients, allowing them to resume more normal activities and improve their overall function.

How to prepare

Preparing for the Intracept Procedure involves discussing your medical history and current medications with your doctor, who will provide specific instructions. You may need to stop certain medications, such as blood thinners, and avoid eating or drinking for several hours before the procedure.

Before the procedure, your doctor will conduct a thorough evaluation to ensure the Intracept Procedure is appropriate for you. This typically includes reviewing your medical history, performing a physical exam, and analyzing your MRI scans to confirm the presence of Modic changes and rule out other causes of your back pain. You will receive detailed instructions from your healthcare team regarding any medications you need to stop taking. For example, blood-thinning medications (anticoagulants) usually need to be paused for a specific period before the procedure to reduce the risk of bleeding. Always follow your doctor's advice carefully. It is also common to be instructed not to eat or drink anything for a certain number of hours before the procedure, usually after midnight the night before. This is important if you will receive sedation. Arrange for someone to drive you home after the procedure, as you will not be able to drive yourself due to the effects of sedation.

What happens during

During the Intracept Procedure, you will lie on your stomach, and the area will be numbed. Using X-ray guidance, a small incision is made, and a specialized probe is advanced into the affected vertebra. Radiofrequency energy is then delivered to ablate the basivertebral nerve, typically taking about an hour.

The procedure usually takes place in an outpatient surgical center or hospital. You will be positioned on your stomach on a procedure table. To ensure your comfort, you will likely receive local anesthesia to numb the skin and deeper tissues, and you may also be given light sedation to help you relax. The clinician will use fluoroscopy (a type of real-time X-ray imaging) to guide the instruments precisely. A small incision, typically less than half an inch, is made in your back. Through this incision, a specialized cannula (a thin tube) is carefully guided into the vertebral body, reaching the area where the basivertebral nerve is located. Once the cannula is in the correct position, a radiofrequency probe is inserted through it. This probe delivers controlled radiofrequency energy, which heats the tip and creates a small lesion (ablation) to disable the basivertebral nerve. This process typically takes about 15 minutes per nerve. After the ablation is complete, the probe and cannula are removed, and the small incision is covered with a bandage. The entire procedure usually lasts about 60 to 90 minutes.

Recovery & timeline

Recovery from the Intracept Procedure is generally quick, with most people returning home the same day. You may experience some soreness at the incision site for a few days. Your doctor will provide specific instructions for activity restrictions, but many people can resume light activities within a few days and more strenuous activities within a few weeks.

Immediately after the procedure, you will be monitored in a recovery area for a short period, typically an hour or two, to ensure you are stable before being discharged. You will need someone to drive you home due to the sedation. It's common to feel some mild pain or soreness at the incision site for a few days. Over-the-counter pain relievers, as recommended by your doctor, can help manage this discomfort. You should avoid strenuous activities, heavy lifting, and twisting movements for a period specified by your clinician, usually a few days to a couple of weeks. Many people can return to light daily activities within a few days. Full recovery and the full benefits of pain relief may take several weeks as the nerve heals and pain signals diminish. Your doctor will schedule follow-up appointments to monitor your progress and provide guidance on gradually increasing your activity levels and potentially starting physical therapy.

Risks & side effects

Like any medical procedure, the Intracept Procedure carries potential risks and side effects, though serious complications are rare. These can include temporary pain at the incision site, infection, bleeding, nerve injury, or a reaction to anesthesia. Your doctor will discuss these risks with you before the procedure.

While the Intracept Procedure is considered minimally invasive, it is not without potential risks. The most common side effect is temporary pain, soreness, or bruising at the site where the needle was inserted. This discomfort usually resolves within a few days. Less common but more serious risks include infection, which can be minimized by sterile techniques, and bleeding. There is also a small risk of nerve damage, though this is rare due to the precise X-ray guidance used during the procedure. Allergic reactions to anesthesia or medications used during the procedure are also possible. Your doctor will carefully review your medical history and discuss all potential risks and benefits with you. They will also explain what to watch for after the procedure, such as signs of infection (fever, increased redness, swelling, or pus at the incision site) or worsening pain, and when to contact their office.

Success rate

Studies show that the Intracept Procedure can significantly reduce chronic low back pain for many patients who meet the specific criteria. Many people experience sustained pain relief and improved function for at least two years, with some studies reporting a notable reduction in pain intensity and disability.

The success of the Intracept Procedure is generally measured by the reduction in pain intensity and improvement in functional ability. Clinical studies have shown positive outcomes for carefully selected patients whose chronic low back pain is linked to Modic changes. For example, some studies indicate that a significant number of patients experience a clinically meaningful reduction in pain. Many individuals report sustained pain relief and improved quality of life, including better sleep and increased ability to perform daily activities, for at least two years following the procedure. It's important to understand that success rates can vary among individuals, and the procedure may not eliminate pain entirely for everyone. Your doctor will assess whether you are a suitable candidate, as patient selection based on specific diagnostic criteria (like Modic changes on MRI) is crucial for achieving the best possible outcomes.
