ABSTRACT
Axial neck and back pain after cervical spinal surgery is a common postoperative complication and can last for years. It is sometimes refractory to conventional treatments such as pharmacotherapy and spinal cord stimulation (SCS). Peripheral nerve field stimulation (PNFS) was recently introduced as an alternative treatment in the management of axial back pain into the occipital/craniofacial region and trunk in occipital neuralgia, post-herpetic neuralgia, and low back pain after lumbar spine surgery. However, PNFS has not been applied to axial neck pain. The patient suffered from occipital neuralgia and axial back pain after cervical spine surgery. In addition to PNFS of the greater occipital nerves for occipital neuralgia, we subcutaneously implanted two electrodes into the bilateral neck regions parallel with a sequential arrangement of the cervical spine. The electrodes were placed immediately above the trapezius muscles and electrical paresthesia was enhanced by posterior neck muscle twitches, fully covering the areas with axial neck pain. Both electrodes successfully achieved an almost 70% decrease in occipital and axial neck pain. Since axial neck pain after cervical spinal surgery often affects patients' health-related quality of life, neuromodulation in the form of PNFS may have the potential to become a novel alternative to conventional pain treatments for medically refractory axial neck pain.
