AbstractWe present a detailed description of the surgical technique and the preliminary results of an endoscopic denervation for patients with chronic low back pain (CLBP) originating from the facet joints (FJ). Endoscopic denervation of the medial branches of the dorsal rami supplying the FJ has recently been appraised as providing excellent intraoperative visualization and long term pain relief for these patients. Conventional endoscopic rhizotomy has been expanded to include a the precise localization of 3D navigation. A surgical description and the results of our first four patients treated with 3D navigated endoscopic rhizotomy (3DNER) are presented. Four patients with a mean age of 59years and a follow-up time of 2months were included. All patients reported pain reduction in the immediate postoperative period, while three patients (75%) had long lasting relief. The patient without persisting relief had previously sustained a lumbar disc prolapse and only achieved minor pain relief with preoperative FJ infiltration, compared to the significant relief that was seen in the other patients. In contrast to conventional rhizotomy, 3DNER enables the surgeon to ablate more precisely and extensively, which is especially useful if scar tissue is present from previous injuries or surgeries. When successful, this technique may provide long lasting pain relief, especially if the preoperative FJ infiltrations are followed by a substantial pain reduction. Copyright © 2015 Elsevier Ltd.
