“…The investigators did not find any of these complications in their study population. Abd-Elsayed et al 19 similarly presented 6 cases of patients undergoing RFA in the setting of previously implanted spinal hardware and did not find any adverse sequelae.…”

Peri‐procedural Management of Implanted Spinal Cord Stimulators in Patients Undergoing Radiofrequency Ablation: A Case Report and Manufacturer‐Specific Recommendations

Introduction Radiofrequency ablation (RFA) and spinal cord stimulation (SCS) are 2 common modalities used in management of various pain conditions. RFA generates heat and an electromagnetic field that can theoretically interfere with the functionality and longevity of the SCS device. This is problematic for patients who need RFA and have previously undergone implantation of an SCS device. Case Description We present a case highlighting the safe use of bipolar RFA in a patient who had previously undergone implantation of a cervical SCS device. Discussion We also present device‐specific industry guidelines and recommendations for performing RFA in patients following SCS device implantation.

“…This is because patients who have undergone surgery often suffer from further joint degeneration secondary to the surgery itself [20], which leads to additional, subsequent pain that is best treated with RFA [19]. Unfortunately, ''there is a theoretical risk involved with treating patients with existing spinal hardware with RFA, as the needle tip used for the procedure ends up in close proximity to this metal hardware [21].'' The ultimate concern is that the metal hardware will serve as a heat sink, increasing the risk of thermal energy damage in the tissues surrounding it as well as drawing heat energy away from the intended site and thus reducing overall efficacy [21].…”

Introduction: Radiofrequency ablation (RFA) is an interventional procedure that provides pain relief by using thermal energy to disrupt peripheral nerves carrying nociceptive signals back to the central nervous system. In the past, having implantable hardware at the planned site of RFA was considered to confer increased risk of adverse outcomes given the theoretical risk of heating of the hardware components. The present study examines patient outcomes to determine whether the efficacy of RFA was affected by the presence of implanted hardware directly at the site. Methods: This was a retrospective case-control study that included 52 patients who received RFA procedures in the presence of hardware at the site of RFA and a control group of 170 patients who received RFA procedures in the absence of hardware. Data were collected from electronic medical records entered into an Excel sheet and then analyzed using SPSS version 22. Outcomes tested included post procedure pain scores, percent, and duration of improvement, if any. Results: We found no statistically significant difference in measured outcomes between either group. Conclusions: This study provides some evidence in support of the theory that RFA procedures performed on patients with pre-existing hardware have similar efficacy when compared to their hardware-free counterparts.
