Analysis Of The Clinical Efficacy Of Q-TLIF In Single-Segment Degenerative Lumbar Spinal Stenosis

Objective:This study is to analyze the early clinical efficacy of quick transforaminal lumbar interbody fusion(Quick Transforaminal Lumber Interbody Fusion,Q-TLIF)in the treatment of degenerative lumbar spinal stenosis(Degenerative Lumbar spinal Stenosis,DLSS).Methods:Patients with single-level degenerative lumbar spinal stenosis hospitalized in our hospital from January 2020 to October 2022 were retrospectively analyzed.A total of 58 patients were selected for this study according to the inclusion criteria and exclusion criteria.According to the surgical methods,the study was divided into two groups: 28 patients in Group A(Q-TLIF group)were treated by quick transforaminal lumbar intervertebral fusion,30 patients in group B were in the control group,and treated with percutaneous endoscopic lumbar interbody fusion(Percutaneous Endoscopic Lumbar Interbody Fusion,PELIF)(PELIF group).General data(gender,age,duration,responsibility segment),operation length,incision length,postoperative time,hospital days,complications,etc.,the operation was evaluated by using Oswestry disability index,Visual analogue scale,and a modified version of the Macnab standard.Results:A total of 58 patients were collected and analyzed,including 28 in Group A(Q-TLIF)and 30 in Group B(PELIF).General data: The differences in gender,age,disease duration,and the surgical responsibility segment were not statistically significant(all P> 0.05).Perioperative data: The differences in surgical incision length,operation length,postoperative time and hospitalization days between the two groups were significant(both P<0.05).The incision length and hospitalization days of patients in group A were significantly greater than those in group B,and the operation time and postoperative time were significantly less than that in group B;There was no significant difference in the incidence of complications between the two groups(P> 0.05).Comparison of clinical efficacy:VAS scores decreased significantly before surgery,postoperative day 1,postoperative day 7 and the last follow-up,and there was no significant difference in VAS scores between the two groups at all time points.The ODI scores decreased before,day 7,1month and last follow-up;the ODI score in Group A was significantly higher than those in Group B at day 7 and January,and there was no significant difference between the ODI scores before and the last follow-up.The rate of Macnab grade was 92.9% in group A and 90.0% in group B,and the difference was not statistically significant(P >0.05).Conclusion:(1)Q-TLIF and PELIF can achieve good early clinical efficacy,indicating that these two surgical methods in the clinical treatment of single segment degenerative lumbar spinal stenosis are feasible,and the early efficacy is comparable;(2)Q-TLIF has more advantages in operation time and postoperative local time,which meets the characteristics of minimally invasive,fast and safe;but it has no advantages over PELIF in surgical incision and hospital stay.Overall,both are effective minimally invasive procedures for DLSS.
