Endoscopic rhizotomy (denervation of facet joints) is a procedure, where under the X-ray guidance of a C-arm, an endoscope is placed in the area of the medial branch of the spinal nerve. Subsequently, the tissue around the medial branch is visualized through the endoscope. Under this visual guidance, we dissect the tissue with a sterile grasper to let us visualize the nerve structure. In the end, the medial branch is coagulated with a radiofrequency probe under the direct visualization of an endoscope. The procedure is finished by removing the endoscope and closing up the incision with 1-2 sutures.
