Clinical Efficacy Analysis Of OLIF,MIS-TLIF And Open-TLIF In The Treatment Of Single Level Degenerative Diseases Of Lumbar Spine

Objective: The purpose of this study is to probe the clinical therapeutic effect 、operative complications and radiological outcomes of oblique lumbar interbody fusion(OLIF),minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF),and open transforaminal lumbar interbody fusion(Open-TLIF)in the treatment of vertebrae lumbales single segment degenerative disease.Methods: Data of patients undergoing interbody fusion surgery due to single segmental degenerative diseases of lumbar vertebrae in the Department of Orthopaedics of the affiliated Hospital of Kunming University of Technology(the first people’s Hospital of Yunnan Province)from January 2021 to January 2022 were included and collected.On the basis of the fusion of admission passage,they were divided into OLIF therapeutic group,MIS-TLIF therapeutic group and Open-TLIF therapeutic group.The operation duration,intraoperative blood loss,postoperative drainage volume,the length of hospital stay after surgery,complications during perioperative period,VAS-lowback score,VAS-leg score,ODI score,JOA score,excellent and good rate,height of segmental intervertebral space,lumbar lordotic angle and interbody fusion rate were recorded and compared among the three groups.Results: The operation duration,the length of hospital stay after surgery and the amount of intraoperative blood loss in MIS-TLIF and Open-TLIF groups were significantly higher than those in OLIF groups,and the postoperative drainage volume in the Open-TLIF group was obviously superior than that in the MIS-TLIF group.The VAS-lowback grading,VAS-leg grading,ODI grading,JOA grading,intervertebral height and lumbar lordosis angle of the three groups were sharply better than those before surgery at all time points of follow-up(P < 0.05).However,when patient data were collected on the first day after surgery,it was found that patients in the OLIF group were significantly better than those in the MIS-TLIF and Open-TLIF groups in VAS-lowback grading,VAS-leg grading,ODI grading,JOA grading,intervertebral tallness and lumbar lordosis angle.There were no significant differences among the three groups in the rate of interbody fusion,the rate of surgical complications,and the rate of good and good at 1 year follow-up.Conclusions: 1.Compared with MIS-TLIF and Open-TLIF,OLIF shortens operation time,reduces intraoperative blood loss and postoperative hospital stay,and has no drainage tube and catheter after operation,so patients recover more quickly.2.OLIF has more advantages than MIS-TLIF and Open-TLIF in restoring intervertebral height and improving lumbar lordosis.3.Three surgical methods are reliable choice for the treatment of lumbar degenerative diseases,can obtain good imaging findings and clinical efficacy,safety and effectiveness are good.
