Lumbar Transforaminal Epidural Injection in Cincinnati - APSI Wellness
Learn about lumbar transforaminal epidural steroid injections for targeted nerve root pain relief at APSI Wellness in Cincinnati.
Lumbar Transforaminal Epidural Steroid Injection — A lumbar transforaminal epidural steroid injection delivers medication directly to a specific nerve root through the neural foramen, providing the most targeted epidural approach for sciatica and radicular pain.
What Is a Lumbar Transforaminal Epidural Steroid Injection?
A lumbar transforaminal epidural steroid injection (TFESI) is a highly targeted form of epidural injection that delivers corticosteroid medication directly to a specific nerve root as it exits the spinal canal through the neural foramen. Unlike interlaminar epidurals that deliver medication broadly into the epidural space, the transforaminal approach places medication precisely at the site of nerve root compression or inflammation.
This targeted approach makes TFESI particularly effective for unilateral (one-sided) radicular pain, commonly known as sciatica.
How Does It Work?
The neural foramen is the bony opening on each side of the spine where nerve roots exit the spinal canal. When a herniated disc, bone spur, or other structure compresses a nerve root at this level, it causes inflammation, pain, and often radiating symptoms down the leg.
The transforaminal injection:
Delivers anti-inflammatory medication directly to the inflamed nerve root
Bathes the nerve root and surrounding epidural space in corticosteroid
Provides both diagnostic information (identifying the specific painful nerve root) and therapeutic benefit
Conditions Treated
Lumbar radiculopathy (sciatica) — radiating leg pain from a compressed nerve root
Herniated or bulging disc — disc material compressing a specific nerve root
Foraminal stenosis — narrowing of the neural foramen causing nerve compression
Degenerative disc disease — with associated nerve root inflammation
Post-surgical radiculopathy — persistent nerve root pain after spine surgery
What to Expect During the Procedure
Before: Stop blood-thinning medications as directed. Arrive with a driver.
During: Positioned face-down on a fluoroscopy table, the skin is cleaned and numbed. Using oblique fluoroscopic views, the physician guides a thin needle into the neural foramen alongside the target nerve root. Contrast dye confirms proper flow around the nerve root. The steroid/anesthetic mixture is slowly injected. The procedure takes 15-20 minutes.
After: You'll rest for 15-30 minutes. Temporary leg numbness on the treated side is expected. Most patients resume light activities the next day. Full pain relief from the steroid may take 3-7 days to develop.

Frequently Asked Questions
How is this different from a regular epidural injection?
A transforaminal epidural targets a specific nerve root by entering through the neural foramen, while an interlaminar epidural enters from the back between vertebrae and spreads medication more broadly. The transforaminal approach is preferred when a specific nerve root is the suspected pain generator.
How many injections will I need?
Most treatment plans involve 1-3 injections. If the first injection provides significant relief, a second may be performed to extend the benefit. No more than 3-4 injections are typically recommended per year.
Will this tell my doctor if I need surgery?
Yes. The transforaminal approach has excellent diagnostic value. If injecting medication at a specific nerve root provides significant relief, it confirms that nerve root as the pain source, which can help guide surgical decision-making if needed.
How long does relief last?
Relief duration varies from weeks to several months. The injection works best as part of a comprehensive plan including physical therapy to address the underlying cause.
Can both sides be injected at the same time?
Bilateral transforaminal injections can be performed, but many physicians prefer to treat one side at a time to maintain diagnostic clarity and minimize risk.
