What is Transforaminal Epidural Steroid Injection?
A transforaminal epidural steroid injection (TFESI) is a minimally invasive procedure used to deliver anti-inflammatory medication (typically a corticosteroid) directly into the nerve root canal (foramen) where spinal nerves exit the spinal column.
Itβs commonly used for back or neck pain that radiates into the arms or legs due to nerve root irritation or compression β such as in herniated discs, spinal stenosis, or sciatica.
