Background: Transforaminal percutaneous endoscopic lumbar discectomy (TF-PELD) is a minimally invasive technique with high radiation exposure. The purpose of this study was to compare radiation exposure of ultrasound-guided TF-PELD with fluoroscopy-guided TF-PELD.
Methods: In this prospective randomized controlled clinical trial, 60 patients with lumbar disc herniation were enrolled and randomly assigned to 2 groups (30 cases in each group): the ultrasound-guided group or the fluoroscopy-guided group.
