Interlaminar endoscopic uniportal approach for implantation of a paddle lead larger than 10 mm for spinal cord stimulation: illustrative case.

Background: The authors aim to describe a new technique for implantation of a spinal cord stimulation paddle lead sized over 10 mm through an endoscopic uniportal approach. A new endoscopic cannula was developed for the passage of a paddle lead width between 10 and 13 mm. The distal portion of the cannula was designed with a larger opening, providing better visibility of the anterior portion of the adjacent structures, thus allowing a panoramic view of the electrode passage.
