Nerve Root Injection/Transforaminal Epidural
Nerve root injections are a special type of epidural injection referred to as transforaminal epidural steroid. Instead of bathing several nerve roots as with an epidural injection, only one nerve root is injected but with a higher dose of steroid. Often this is done with a far lateral herniated disc and/or foraminal stenosis. It may be helpful for surgeons for diagnosis of the correct level. Nerve root injections do require use of x-ray.
