Abstract

Epidural neuroplasty is a treatment modality for back pain and/or radiating pain caused by mechanical compression or neural inflammation of intra-spinal neural structures. Since epidural neuroplasty was first introduced as a treatment for pain caused by epidural adhesion such as failed back surgery syndrome (FBSS), it has been performed as a treatment for many kinds of pain of spinal origin including acute/chronic herniation of intervertebral disc, radiculopathy, spinal stenosis, FBSS, epidural adhesion, vertebral compression fracture, vertebral metastasis, resistant multilevel degenerative arthritis, epidural scar pain by infection or meningitis, and whiplash injury. Epidural neuroplasty is a catheterization technique used to treat back pain and/or radiating pain by injecting therapeutic drugs into lesions of epidural space shown as a filling defect in epidurogram. Usually, normal saline, local anesthetics, and steroid are used as therapeutic drugs. The exact mechanisms of action of the procedure are unknown but include 2 postulated mechanisms of action for pain relief. i.e., mechanical adhesiolysis by volume effect and chemical adhesiolysis by injected drugs. Relative large volumes of normal saline injection resolve adhesions and wash out accumulated pain substances; local anesthetics are used for stabilization and analgesia of flaring neural structures and for pain management for procedure related pain; and steroid is used for the treatment of inflammation of neural and peri-neural structures. The resolution of filling defect can be verified by post-procedure epidurogram. The key point of epidural neuroplasty for good results, is the exact localization of the epidural catheter into the epidural lesion.
