Abstract
A full-endoscopic rhizotomy of the lateral branches of sacral nerves provides satisfactory results in treating sacroiliac (SI) joint pain. However, the conventional C-arm fluoroscopy can barely identify anatomical landmarks such as the dorsal sacral foramen. The imprecise images might compromise the efficacy and durability of the rhizotomy. The authors introduced a full-endoscopic rhizotomy workflow with a three-dimensional (3D) robotic C-arm navigation guidance. The current technique is innovative, effective, and safe for relieving SI joint pain. The 3D navigation system helps the operator quickly locate the medial branches at the L5 level and sacral lateral branches from S1, S2, and S3 dorsal foramina. The full-endoscopic rhizotomy can be efficient with an accurate localization.
