Interlaminar Epidural Injection

An epidural steroid injection is an injection of local anesthetic and steroid into the epidural space. The epidural space is a space located within the spine, just outside of the sac containing spinal fluid.

​

The goal of an epidural steroid injection is to provide pain relief by reducing the inflammation (swelling) of the nerve roots as they exit the spine. An epidural steroid injection will not correct the preexisting medical problem (such as spinal stenosis, herniated or bulging disc) causing the pain, but it is intended to decrease inflammation, improve the level of pain and help with improvement in normal function.
