Transforaminal and Interlaminar Epidural Steroid Injections
Transforaminal Epidural Steroid Injections
A transforaminal injection is a long acting steroid delivered into a nerve root exit in the spine known as a foramen. The injection helps to reduce inflammation and swelling in the spinal cord nerve roots and relieves pain and numbness. A transforaminal injection consists of a small dosage of steroid medication mixed with saline and local anesthesia. The anesthesia numbs the area so the injection often feels like just pinching and pressure.
Immediate pain relief is found because of the injection of anesthesia, but this wears off quickly. Effective relief is usually noticeable by the third day after the injection and can last for several months. This treatment is most successful for patients with pain that radiates through the arms or legs rather than just back or neck pain.
Interlaminar Epidural Steroid Injections
Epidural steroid injections, or ESIs, are a minimally invasive treatment that has been used for decades to temporarily relieve low back and leg pain (sciatica). They have been shown to be effective for pain in the neck (cervical) and mid-spine (thoracic) as well. While they do not treat serious underlying spinal conditions, ESIs are often effective in relieving the chronic pain these conditions often cause.
Comprised of cortisone and a local anesthetic or saline solution, ESIs work by reducing inflammation and flushing out particles that cause swelling and pain. Medication is delivered directly to the source of the pain rather than dispersing it throughout the body, as oral painkillers and steroids do. They are injected into the epidural space, the area between the dura (a membrane covering the brain and spinal cord) and the actual cord itself. Intralaminar ESIs require inserting the needle between the lamina, a small section of bone that covers the spinal cord, of two vertebrae. The medication enters the epidural space in the midline and from there is able to reach the nerve roots on either side of the spine.
