Background: The sacroiliac joint (SIJ) is a major source of pain in patients with chronic low back pain. Radiofrequency ablation (RFA) of the lateral branches of the dorsal sacral rami that supply the joint is a treatment option gaining considerable attention. However, the position of the lateral branches (commonly targeted with RFA) is variable and the segmental innervation to the SIJ is not well understood. Objectives: Our objective was to clarify the lateral branches’ innervation of the SIJ and their specific locations in relation to the dorsal sacral foramina, which are the standard RFA landmark. Methods: Dissections and photography of the L5 to S4 sacral dorsal rami were performed on 12 hemipelves from 9 donated cadaveric specimens. Results: There was a broad range of exit points from the dorsal sacral foramina: ranging from 12:00 – 6:00 position on the right side and 6:00 – 12:00 on the left positions. Nine of 12 of the hemipelves showed anastomosing branches from L5 dorsal rami to the S1 lateral plexus. Limitations: The limitations of this study include the use of a posterior approach to the pelvic dissection only, thus discounting any possible nerve contribution to the anterior aspect of the SIJ, as well as the possible destruction of some L5 or sacral dorsal rami branches with the removal of the ligaments and muscles of the low back. Conclusion: Widespread variability of lateral branch exit points from the dorsal sacral foramen and possible contributions from L5 dorsal rami and superior gluteal nerve were disclosed by the current study. Hence, SIJ RFA treatment approaches need to incorporate techniques which address the diverse SIJ innervation. Key words: Sacroiliac joint pain, radiofrequency ablation, dorsal sacral rami, low back pain

The posterior sacral network is a complex meshwork of lateral branches of the dorsal sacral rami that innervate the posterior aspect of the sacroiliac joint. Pain arising from this joint can be diagnostically targeted using either a fluoroscopic or ultrasound technique to determine if the patient would benefit from radiofrequency ablation of the lateral branches. Injecting local anesthetic near the dorsal foramina using these techniques will temporarily block the transmission of pain by the lateral branches from the sacroiliac joint. This chapter covers the anatomy of the posterior sacral network, discusses the details of the two techniques for lateral branch blocks and evidence for their utility, provides information about the risks and contraindications associated with the techniques, and concludes by discussing the implications of the procedure.

Background. Radiofrequency ablation (RFA) is a less invasive technique for treatment of sacroiliac joint (SIJ) pain. Objective. To evaluate the feasibility and efficacy of endoscope-guided RFA for the treatment of CLBP from the SIJ complex. Methods. In this retrospective study, the medical records of 17 patients who underwent endoscope-guided RFA of the SIJ complex were reviewed. A bipolar radiofrequency probe was used to lesion the posterior capsule of the SIJ as well as the lateral branches of S1, S2, S3, and the L5 dorsal ramus in multiple locations. We visualized the ablation area using endoscope. We assessed visual analogue scale (VAS) and the Oswestry disability index (ODI) preoperatively, immediately postop, and at 1-, 3-, and 6-month postop outpatient clinic visits. Patient satisfaction of the procedure was assessed in percentages. Results. The mean duration of operation was 20 to 50 minutes. The mean VAS and the ODI scores decreased significantly immediately after the procedure and were kept significantly lower than baseline levels during the follow-up periods. No complications occurred perioperatively and during the follow-up periods. 88.6% of patients were satisfied with the procedure. Conclusions. Our preliminary results suggest that endoscope-guided RFA may be alternative option to treat CLBP secondary to SIJ complex.
