Popis: Abstract Introduction In percutaneous endoscopic lumbar discectomy (PELD), pain occurs when the posterior longitudinal ligament (PLL) is exposed, removed, and decompressed. However, pain characteristics of the PLL stimulated in PELD have not been reported. Methods A total of 932 patients underwent PELD under local anesthesia. Pain distribution and intensity were recorded on a posterior body diagram during the operation. Pain intensity was assessed by the visual analog scale scores for the back (VAS-B). The PLL specimens were collected and observed using hematoxylin–eosin (HE) staining and immunohistochemistry. Results Patients with lumbar disc herniation (LDH) at L4/5 and L5/S1 had pain foci in different regions. The mean VAS-B scores between the ventral and dorsal sides of the PLL were 6.14 ± 0.97 and 4.80 ± 1.15, respectively (P
