Background And ObjectivesFull-endoscopic sacroiliac joint denervation (FE-SJD) is a novel technique for the management of pain secondary to sacroiliac joint dysfunction. The aim of this study was to assess the long-term efficacy, safety, clinical outcomes, and outcome predictors of uniportal full-endoscopic sacroiliac joint denervation.MethodsFrom 2019 to 2021, a total of 47 consecutive patients with pain secondary to sacroiliac joint dysfunction underwent uniportal FE-SJD through posterior approach by a single fellowship-trained spine surgeon. A retrospective analysis of perioperative parameters, complications, and clinical outcomes were obtained prospectively.ResultsThe patient cohort had a mean age of 59.4 ± 14.0 years, with 63.8% females. Symptom duration averaged 62.1 ± 53.7 months. The mean operative time was 57.1 ± 16.8 minutes. All patients were discharged on the same day of surgery. Significant improvement was noted in preoperative visual analog score (back) and Oswestry Disability Index scores at 3, 6, 12 months, and 2 years (P < .001). Thirty-four patients (72.3%) returned to normal functioning with an average of 82% pain relief and a satisfaction rate of 78.7% at a mean follow-up of 18.2 ± 13.1 months. There were no intraoperative complications. One patient had postoperative right L5 dysesthesia. Seven patients (14.9%) underwent contralateral FE-SJD due to satisfaction with the index procedure but residual pain on the contralateral side. Concomitant lumbar issues correlated with less functional improvement at 2 years (P = .009).ConclusionThe long-term clinical results of FE-SJD are favorable. Endoscopic denervation of the dorsal rami branches supplying the sacroiliac joint represents a safe, effective, and durable option to address pain secondary to sacroiliac joint dysfunction. A significant factor that influences outcomes is the presence of concomitant lumbar pathology. Further research is needed to compare this technique with current available treatment options.Copyright © Congress of Neurological Surgeons 2024. All rights reserved.
