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

Abstract

PTED has the advantages of shorter length of incision, shorter operation time, and shorter length of stay. MED + annular suture is associated with greater preservation of disc height, and showed certain advantages of lower recurrence rate, although there was no statistical difference.
