Extraforaminal Lumbar Nerve Root Stimulation for Neuropathic Pain: A Case Report

Abstract

Electrical stimulation of the spinal cord is commonly used to treat neuropathic pain. However, epidural space adhesion caused by previous surgery may interfere with precise electrical lead placement. We here report a case of successful placement of electrical leads via an extraforaminal approach in the management of recurrent pain after primary spinal cord stimulation. Extraforaminal nerve root stimulation may be an alternative choice for repeated epidural spinal cord stimulation in cases of recurrent neuropathic pain.

Advances in the Treatment of Neuropathic Pain by Sympathetic Regulation

“…Traditional treatment methods include drug therapy, physical therapy, such as exercise and rehabilitation, and psychological therapy such as psychological counseling; however, often cannot fundamentally relieve patients' pain symptoms [14][15][16]. With the development of neuroregulatory techniques, spinal cord electrical stimulation and dorsal root ganglion pulsed radiofrequency are commonly used to treat neuropathic pain [17,18]. Although SCS is effective in the treatment of neuropathic pain, owing to the implantation of electrodes into the spinal canal, the risk of epidural infection is positively correlated with the implantation time, and there is a risk of electrode displacement or even fracture.…”
