Abstract Objective: To investigate the effect of percutaneous foraminoscopic nucleus pulposus extraction on lumbar motion and complications in patients with lumbar disc herniation at L4-5. Method: A total of 86 patients with L4-5 lumbar disc herniation admitted to the Ninth People's Hospital of Jiujiang City from January 2019 to January 2022 were selected and divided into the conventional group and the experimental group according to random number table method, with 43 cases in each group. The conventional group underwent fenestration of laminae nucleus pulposus discectomy and the experimental group underwent percutaneous foraminoscopic nucleus pulposus extraction. Lumbar function [Japanese orthopaedic association lumbar function (JOA) score], Oswestry disability index (ODI) score, lumbar motion and incidence of complications were compared between the two groups. Result: There was no significant difference in lumbar function scores between the two groups before operation (P<0.05); 1 month after operation, JOA scores in both groups were higher than those before operation, that in experimental group was higher than that in conventional group (P<0.05); 1 month after operation, ODI scores in both groups were lower than those before operation, that in experimental group was lower than that in conventional group (P<0.05). There was no significant difference in the range of motion of flexion and lumbar extension before operation between the two groups (P>0.05); the range of flexion and lumbar extension in both groups were higher than those before operation at 1 month after operation, and those in experimental group were higher than those in the conventional group (P<0.05). The complication rate in experimental group was lower than that in conventional group (字2=4.692, P=0.030). Conclusion: The treatment of L4-5 lumbar disc herniation by percutaneous foraminoscopic nucleus pulposus extraction can significantly improve the function of lumbar spine, improve lumbar motion and reduce complications.
