the epidural steroid injection procedure is quick and simple. while it is common for people to be concerned prior to the procedure it is actually frequent to hear from patients afterward: "is that all? " the spinal cord rests in the spinal canal. the nerve roots branch out from the spinal cord at each level of a spinal vertebra (the bony building blocks of the spine). the cord is protected by cerebrospinal fluid which serves as a shock absorber for the cord. the csf is held in place by a membrane with several layers one of which is called the dura from the greek for tough (think of "durable"). the greek word "epi" means "outside of. " the epidural space is outside of this tough membrane. during an epidural steroid injection a needle and syringe are used to enter the epidural space and deposit small amounts of long-lasting steroids around the inflamed spinal nerve. a fluoroscope (a viewing instrument using x-rays) is used to visualize the local anatomy during the injection. the epidural steroid injection specifically targets the inflamed area and treats it with a maximal amount of steroids thereby minimizing exposure of the rest of the body to the steroids.
