Long-Term Efficacy of a Novel Extraforaminal Approach for Nerve Root Stimulation in Complex Regional Pain Syndrome: A Case Report.

Abstract

BACKGROUND: Neuromodulation techniques can be employed as part of the treatment approach for refractory complex regional pain syndrome (CRPS). CASE REPORT: We present a case report of a 62-year-old male patient with CRPS of the lower limb who underwent spinal nerve root stimulation using a novel extraforaminal lead placement as a treatment modality after the failed replacement of a defective dorsal root ganglion lead. This case report highlights the successful long-term application of dorsal nerve root stimulation with an alternative extraforaminal lead placement technique, resulting in significant pain relief and improved functional outcomes in a patient with refractory CRPS. CONCLUSIONS: The novel anatomical approach and neurostimulation technique described in this case provide a promising alternative for patients who have not responded to other treatment modalities.
