Sustained relief with spinal cord stimulator despite anterior lead migration: a case report.

Abstract

Lead migration is a common complication of spinal cord stimulation, although anterior migration is rare. While early studies suggested that anterior stimulation may produce analgesic effects, it is thought to be poorly tolerated due to abnormal paresthesia and muscle contractions due to its proximity to the corticospinal tract. This case report presents a unique case of sustained pain relief despite anterior lead migration, which suggests that anterior column stimulation may hold clinical significance for pain management. Further studies are needed to explore its analgesic mechanisms and potential therapeutic application. Strategies to prevent lead migration, particularly in the early postoperative period, are also crucial for optimizing outcomes.
