Objective:
To describe the use of peripheral nerve stimulation targeting the sacral lateral branches as a treatment for sacroiliac joint mediated low back pain refractory to conventional therapies.
Methods:
A 67-year-old female with chronic sacroiliac joint (SIJ)-mediated low back pain, refractory to conservative management and sacral lateral branch radiofrequency ablation, subsequently underwent a trial and implantation of peripheral nerve stimulation (PNS) targeting the sacral lateral branches.
Results:
The PNS trial achieved 60% pain reduction without adverse events. After permanent implantation, 12-month follow-up showed 70% sustained pain relief and ODI improvement from 68% to 28%.
Conclusion:
PNS of the sacral lateral branches, performed using a novel technique, appears to be a safe and effective treatment for SIJ-mediated low back pain refractory to standard therapies. Further studies are warranted to validate these findings.
