Objective To investigate the effects of oblique lumbar interbody fusion treatment on the perioperative indexes

traumatic stress indexes and Oswestry dysfunction index（ODI） scores of patients with lumbar spinal stenosis. Methods Ninety patients with lumbar spinal stenosis admitted to a hospital in Zhangzhou from December 2016 to December 2019 were selected and divided into a control group（46 cases） and an observation group（44 cases） using a random number table. Patients in the control group were treated with posterior lumbar interbody fusion and patients in the observation group were treated with oblique lumbar interbody fusion

and the perioperative indexes

pre-and postoperative visual analog scale（VAS） scores

ODI scores

serum C-reactive protein（CRP） and creatine kinase（CK） levels and postoperative complications in the two groups were compared. Results The intraoperative bleeding and drainage were less in the observation group than in the control group

and the time to ambulation and hospital stay were shorter than those in the control group

all with statistically significant differences（P

<

0.05）. The VAS and ODI scores at 3 and 6 months after surgery were lower than those before surgery and lower in the observation group than in the control group

with statistically significant differences（P

<

0.05）. The serum CRP and CK levels in the 2 groups were higher at 12 h

24 h and 48 h after surgery than before surgery

and lower the serum CRP and CK levels at 48 h after surgery than at 12 h and 24 h after surgery

and the serum CRP and CK levels in the observation group were lower than those in the control group at 12 h

24 h and 48 h after surgery

all with statistically significant differences（P

<

0.05）.The incidence of postoperative complications was 4.55%（2/44） in the observation group

which was lower than that of 15.57%（9/46） in the control group

and the difference was statistically significant（χ

=

4.729

P=0.030）. Conclusion Oblique lumbar interbody fusion for lumbar spinal stenosis is safer than the posterior approach

and patients have less postoperative tissue trauma stress and less postoperative pain

which can promote the recovery of lumbar spine function.
