How I Do It: Percutaneous Transforaminal Endoscopic Discectomy for Lumbar Disk Herniation

Percutaneous transforaminal endoscopic discectomy (PTED) is a minimally invasive technique to treat lumbar disk herniation from a lateral approach. Performed under local anesthesia, the incision size for PTED is around 8 mm with no paraspinal muscle cutting or detachment from their insertion. PTED has been associated with less blood loss, faster rehabilitation, and less scarring of tissue than conventional open microdiscectomy. High-quality randomized controlled trials comparing PTED with open microdiscectomy have not been conducted yet. However, PTED has been proven to be an effective technique allowing patients to return home only 2 hours after surgery. By the means of this article and video (Supplemental Digital Content 1, http://links.lww.com/CLINSPINE/A1), we would like to show the spine surgeon the PTED technique for the treatment of a single-level lumbar disk herniation.
