Abstract：Objective To investigate the relationship between low back pain in percutaneous endoscopic lumbar discectomy (PELD) and resection of calcified lumbar disc herniation. Methods A total of 81 patients with lumbar disc herniation were selected from the Department of Orthopedics of PLA General Hospital from January 2019 to December 2021 who were treated with PELD under local anesthesia. According to the preoperative CT image data, the patients were divided into the calcified group and the non-calcified group. The average visual analog score (VAS) of intraoperative low back pain between the two groups was recorded, the intraoperative low back pain VAS between the two groups was compared, and the excellent and good rate of modified Macnab was used to compare the intraoperative satisfaction. Results There was no demographic significance in two groups. VAS of intraoperative low back pain between two groups, were significantly different (VAS of calcified group by endoscopic clamp was 4.86±1.29 vs non-calcified group was 1.13±0.72, VAS of calcified group by electrocoagulation was 5.43±1.74 vs non-calcified group was 2.07±1.91). Besides, modified MacNab criteria between the two groups were also significantly different (66.66% vs 86.67%; P<0.05). Conclusions The treatment of calcified lumbar intervertebral disc herniation in PELD may lead to severe low back pain in patients who cannot tolerate surgery, and the calcification of intervertebral discs may be a predisposition factor for low back pain.
