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

Area of Science:

• Neuromodulation
• Pain Management
• Medical Device Technology

Background:

• Spinal cord stimulators (SCSs) are established treatments for chronic pain.
• SCSs are typically indicated for failed back surgery syndrome, complex regional pain syndrome, or non-surgical candidates.
• The presence of another electrical pulse device is a relative contraindication for SCS implantation.

Observation:

• This study presents three cases of patients receiving SCS despite having other implanted electrical devices.
• Case 1: Failed back surgery syndrome patient with an implantable cardiac defibrillator (ICD) and SCS.
• Case 2: Non-surgical candidate with a pacemaker receiving SCS for occupational back pain.
• Case 3: Complex regional pain syndrome patient with a bladder stimulator and prior SCS receiving a revision.

Findings:

• No adverse interactions were observed between the co-implanted electrical devices.
• All three patients experienced significant improvements in pain scores following SCS trial.

Implications:

• Co-implantation of SCS with other electrical pulse devices may be a viable option for select patients.
• This approach can expand treatment possibilities for chronic pain management.
• Further research is warranted to establish guidelines for co-implantation of neuromodulation devices.
