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 and typically with sedation.
