Abstract: Objective    To explore the clinical application value of degenerative lumbar spinal stenosis through the intervertebral foramen with percutaneous endoscopic guided by electromagnetic navigation. Methods   A retrospective cohort study was performed. From Sep 2018 to Sep 2019, 63 patients with degenerative lumbar spinal stenosis were treated with percutaneous endoscopic, who were divided into a navigation group (n=27) and a conventional group (n=36). The demographic characteristics and operation-related indexes of the two groups were recorded. Visual analog scale (VAS) and Japanese Orthopedic Association scores (JOA) were used to evaluate and analyze the clinical efficacy.    Results    There was no significant difference in the demographic characteristics and preoperative clinical features between the two groups (P>0.05). There were significant differences in fluoroscopy times, puncture and operation time, postoperative hospital stays between the two group (P<0.05), and there were significant differences in VAS score and JOA score of leg pain preoperative and postoperative in each group (P<0.05). There was no significant difference in the recurrence rate between the two groups (P>0.05).   Conclusions   Percutaneous endoscopic treatment of lumbar spinal stenosis guided by electromagnetic navigation can reduce the fluoroscopy times, puncture and operation time, postoperative hospital stays, thus reducing the radiation exposure during operation and improving the efficiency of positioning and punctruing.
