Transforaminal Epidural Steroid Injection (TFESI) Series
A TFESI involves injecting medication into the epidural space, where irritated nerve roots are located. This injection uses a long-lasting steroid and may also include a local anesthetic (usually lidocaine). The steroid reduces the inflammation/irritation of the nerves, and the anesthetic works to interrupt the pain signal transmission. The medications also spread to other levels and portions of the spine, further reducing inflammation and irritation. TFESIs can be performed in the cervical, thoracic, lumbar, or sacral portion of the spine.
Our physicians use fluoroscopic guidance to position the needles in the epidural space. The placement is confirmed using contrast dye. This ensures that the medications will be in the proper area in order to relieve pain. Once the needle position is verified, the medication is injected.
