A transforaminal epidural steroid injection (TESI) is a procedure aimed at reducing spinal pain and inflammation, particularly addressing pain that radiates to other areas like the arms, legs, and feet. This injection is administered through the foramina, which are openings where nerves exit the spinal canal and extend to other parts of the body. The term “epidural” indicates that the injection is placed on or around the dura mater, the protective membrane surrounding the spinal cord.
During a TESI, a needle is carefully inserted through the foramen, delivering steroid medications to the space surrounding the nerves. It’s essential to note that this injection doesn’t penetrate the spinal cord or the nerves themselves; instead, it targets the safe space around them. Unlike some other epidural steroid techniques, a TESI typically requires X-ray guidance (fluoroscopy) for enhanced accuracy. This imaging method helps healthcare providers precisely locate and target specific spinal nerves, optimizing the effectiveness of the injection in alleviating pain and inflammation.
Transforaminal epidural steroid injections are used to address various spinal conditions and associated symptoms, including:
The specific type of transforaminal epidural steroid injection—lumbar, cervical, or thoracic—depends on the location of the affected nerves, targeting lower back, neck, or mid-back pain, respectively. These injections offer targeted relief for a range of spinal issues, improving overall comfort and function for patients.
During a transforaminal epidural steroid injection (TESI), you lie on your stomach on an X-ray table. The procedure starts with your provider administering local anesthesia to numb your skin, possibly causing a mild burning or pinching sensation. Additionally, you may receive IV sedation to enhance your comfort without losing consciousness.
Once prepared, your provider uses fluoroscopy for precision. They insert a thin needle into your back, targeting the specific nerve root responsible for your pain. Then, they inject a mixture of anesthetic for immediate pain relief and steroid medications for longer-lasting effects.
This process takes around 30 minutes. The local anesthetic provides temporary relief, while the steroids reduce inflammation and offer more sustained pain management. The fluoroscopy-guided approach ensures accurate placement of the injection for optimal therapeutic benefits.
After receiving a local anesthetic and corticosteroid injection, it’s crucial to follow post-recovery care instructions. For the initial 4–6 hours, expect the local anesthetic to provide pain relief. However, it may take 3–7 days for the corticosteroids to achieve optimal effectiveness. Refrain from driving for 12 hours post-injection. Mild soreness at the injection site(s) for 24–48 hours is normal; alleviate it with ice packs for 20-minute intervals several times daily.
Avoid heat in the injection area for 72 hours; no hot packs, saunas, or steam rooms. You can shower regularly. Resume your regular medication routine immediately, including pain relievers, anti-inflammatories, and blood thinners. Remove the sterile dressing/band-aid either tonight or the next morning after ensuring it doesn’t get wet. Be aware of possible corticosteroid side effects such as flushing, hot flashes, palpitations, insomnia, water retention, anxiety, or headaches, which typically resolve within a few days.
A transforaminal epidural steroid injection targets the area where nerve roots exit the spinal column, delivering medication directly into the neural foramen. This precise approach contrasts with interlaminar epidural injections, which are administered into the central epidural space. By focusing on the specific site of nerve irritation, transforaminal injections can provide more effective relief for conditions like sciatica, herniated discs, and spinal stenosis. This targeted delivery helps reduce inflammation and pain more efficiently, potentially offering longer-lasting benefits compared to other types of epidural injections.
Transforaminal epidural steroid injections are commonly used to treat conditions that cause nerve root irritation or inflammation, such as herniated discs, spinal stenosis, and degenerative disc disease. They are particularly effective for radiculopathy, where nerve pain radiates from the spine to other areas like the legs or arms. These injections can also help manage pain associated with sciatica and certain types of lower back pain. By reducing inflammation and swelling around the affected nerve roots, transforaminal injections can provide significant pain relief and improve mobility.
During a transforaminal epidural steroid injection procedure, you will be positioned on an examination table, usually lying face down. The area of injection will be cleaned and numbed with a local anesthetic. Using fluoroscopic (X-ray) guidance, the physician will insert a thin needle into the neural foramen, the space where the nerve root exits the spine. Contrast dye may be injected to ensure proper needle placement. Once confirmed, a corticosteroid mixed with a local anesthetic is injected into the targeted area. The procedure typically takes about 30 minutes, and you can usually go home the same day.
Relief from a transforaminal epidural steroid injection can vary among patients. Some may experience significant pain relief within a few days, while for others, it may take up to two weeks to notice improvement. The initial relief is often due to the local anesthetic, while the corticosteroid works over time to reduce inflammation and swelling. The duration of pain relief can also vary, with some patients experiencing relief for several weeks to months. Follow-up injections or additional treatments may be necessary for sustained pain management, depending on the underlying condition and individual response.
Transforaminal epidural steroid injections are generally safe, but they carry potential risks and side effects. Common side effects include temporary pain at the injection site, headache, or dizziness. Some patients may experience facial flushing or insomnia for a short period after the injection. Rarely, more serious complications like infection, bleeding, nerve damage, or an allergic reaction to the medications used can occur. Using imaging guidance helps minimize these risks by ensuring accurate needle placement.
Yes, transforaminal epidural steroid injections can be combined with other treatments for comprehensive pain relief. Physical therapy, exercise, and stretching programs can enhance the benefits of the injections by improving strength, flexibility, and overall spinal health. Medications such as anti-inflammatory drugs or muscle relaxants can also be used to complement the effects of the injection. Additionally, lifestyle modifications, ergonomic adjustments, and stress management techniques can help manage symptoms and prevent further injury.
