Analysis of Clinical Results of Three Different Routes of Percutaneous Endoscopic Transforaminal Lumbar Discectomy for Lumbar Herniated Disk

Abstract

All 3 routes of PETLD resulted in good to excellent clinical results. Nevertheless, the postoperative VAS score was higher for the foraminal route than for the intervertebral and suprapedicular routes, probably not because of the surgery but because of the neurologic characteristics of the disk location. The surgeon should consider this problem to alleviate pain postoperatively and counsel to patient well before surgery.
