Microendoscopic Discectomy Combined with Annular Suture Versus Percutaneous Transforaminal Endoscopic Discectomy for Lumbar Disc Herniation: A Prospective Observational Study

Microendoscopic discectomy (MED) and percutaneous transforaminal endoscopic discectomy (PTED) are 2 of the most popular minimally invasive spinal surgery techniques. We are investigating whether minimally invasive early annular closure can achieve a better clinical effect in the treatment of lumbar disc herniation (LDH).
