【Abstract】Objective: To explore the application effectiveness of 3D printed individualised navigation
template in lumbar screw implantation and its effect on patients＇ lumbar spine function and stress hormones．
Methods: A total of 122 patients with lumbar disc herniation and lumbar spinal stenosis in our hospital from
January 2019 to January 2021 were selected．The random number table method was used to randomly divide
122 patients into two groups，with 61 cases in each group．The control group underwent lumbar spine screw im-
plantation，and the 3D printed individualized navigation template assisted the lower lumbar spine screw implan-
tation in the study group．The perioperative indicators，surgical outcomes and complications in the 2 groups were
observed，and the stress hormones ［catalase ( CAT) ，malondialdehyde ( MDA) ，reactive oxygen species
( ＲOS) ］，spinal cord function ［nerve conduction velocity ( NCV) ，latency ( DL) ］and Oswestry Dysfunction
Index Questionnaire ( ODI) and visual analogue scoring method (
