Salvage of a Passive Recharge Burst Spinal Cord Stimulation Implant With 10 kHz Spinal Cord Stimulation for Failed Back Surgery Syndrome: A Case Report.

Spinal cord stimulation (SCS) is a minimally invasive procedure used for a broad spectrum of chronic pain conditions. Unfortunately, complications can occur that may lead to device explantation. The most common reason for explantation is loss of efficacy (LoE). "Salvage therapy" is the conversion from 1 mode of stimulation to another when LoE occurs. Salvage therapy has been described with multiple modes of stimulation. To our knowledge, salvage therapy with high-frequency SCS for LoE with burst SCS has not been previously described. We present a case of salvage therapy utilizing 10 kHz SCS for LoE with a passive recharge burst SCS.
