Abstract:
Objectives:The purpose of this study was to investigate the clinical efficacy of percutaneous endoscopic transforaminal lumbar interbody fusion(PE-TLIF)in patients with single-segment lumbar spinal stenosis and explore the changes of paraspinal muscles and adjacent segmental facet joints of operative segement after PE-TLIF.Methods:28 patients with L4/5 lumbar spinal stenosis treated with PE-TLIF in Beijing Chaoyang Hospital from March 2017 to March 2019 were analyzed retrospectively.The patients consisted of 12 males and 16 females with an average age of 58.0±8.7 years(41-79 years)and were followed up for 40.7±3.6 months(36-58 months).The visual analogue scale(VAS)of low back pain(VAS-LBP)and VAS of leg pain(VAS-LP)were collected at pre-operation,postoperative 1-week follow-up,3-month follow-up,12-month follow-up and the final follow-up;Oswestry disability index(ODI)was evaluated at pre-operation,post-operative 3-month follow-up,12-month follow-up and the final follow-up.CT examination was performed at pre-operation,postoperative 12-month follow-up,24-month follow-up and the final follow-up,the cross-sec-tional area(CSA)and fat infiltration(FI)score of multifidus(MF)were measured,and the degeneration degree of adjacent segmental facet joints was evaluated according to the score of facet joint degeneration.The differ-ences of MF CSA and FI score,as well as adjacent segmental facet joint degeneration were compared be-tween preoperation and postoperation.Results:The VAS-LBP score was 3(2,3)at 1-week follow-up,1(1,2)at 3-month follow-up,1(0,2)at 12-month follow-up,and 1(0,1)at the final follow-up,which was signif-icantly improved compared with the preoperative score of 7(7,8)(P<0.05);the VAS-LP score was 2(1,3)at 1-week follow-up,1(1,2)at 3-month follow-up,1(0,1)at 12-month follow-up,and 0(0,1)at the final fol-low-up,which were significantly improved compared with the preoperative score of 6(5,7)(P<0.05);The ODI at 3-month follow-up was 23%(19%,31%),at 12-month follow-up was 12%(8.5%,17.5%),and at the final follow-up was 7%(4%,15.6%),all significantly improved compared with the ODI before operation of 61%(55%,67%)(P<0.05).The postoperative MF CSAs of 547.12±53.31mm2(12-month follow-up),558.35±52.37mm2(24-month follow-up),and 531.21±56.12mm2(final follow-up)were not significantly changed from the preoper-ative MF CSA of 557.06±46.72mm2(P>0.05).There was no significant difference in FI score between pre-op-eration of 2(2,3)and 12-month follow-up of 3(2,3),24-month follow-up of 3(2,3)and the final follow-up of 3(3,3)(P>0.05).The postoperative facet joint degeneration scores of upper segment facet joint(USFJ)of 5(4,6)at 12-month follow-up,5(4,5)at 24-month follow-up,and 5(4,6)at final follow-up were not signifi-cantly changed from the preoperative 5(4,6)(P>0.05).And there was no significant difference either in facet joint degeneration score of lower segment facet joint(LSFJ)between pre-operation of 5(4,6)and 12-month follow-up of 5(4,5),24-month follow-up of 5(4,6)and the final follow-up of 5(4,7)(P>0.05).Conclusions:PE-TLIF can achieve satisfactory clinical outcomes in the treatment of single-segment lumbar spinal stenosis,which has no significant effect on multifidus in the surgical segment and adjacent segmental facet joints in the mid-to long-term.
