Lack of electrical interference between spinal cord stimulators and other implanted electrical pulse devices

Spinal cord stimulators (SCSs) have been used for decades to treat chronic pain. SCSs are often used to treat patients with chronic back pain caused by failed back surgery syndrome, patients with complex regional pain syndrome, or individuals who are not candidates for surgery. SCSs are a relative contraindication in patients with another electrical pulse device. We present 3 patients who received SCS despite having another implant in place. There was no interaction between devices. The first case was a patient with failed back surgery syndrome who had an implantable cardiac defibrillator and an SCS implant.
