Abstract:
Objective To compare the clinical outcomes between oblique lumbar interbody fusion(OLIF)and transforaminal lumbar interbody fusion(TLIF)for patients with degenerative spondylolisthesis during 2-year follow-ups.Methods Patients with symptomatic degenerative spondylolisthesis who underwent OLIF(46 cases)and TLIF(45 cases)between July 2017 and September 2020 with 2-year follow-ups were retrospectively reviewed.One level or two-level lumbar fusion were included.The primary outcomes were Visual Analogue Scale(VAS)and Oswestry Disability Index(ODI)at 2 years after surgery.The secondary outcomes included radiographic parameters,fusion rate,cage subsidence rate,and permanent nerve injury rate.Results No significantly different changes were noted in VAS-back[2(2,3)vs.2(2,2),P=0.943],VAS-leg[2(2,2)vs.2(2,2),P=0.988],and ODI[17％(10％,22％)vs.14％(10％,22％),P=0.417]between the OLIF group and the TLIF group,respectively.Greater restoration of disc height and segmental lordosis were obtained in the OLIF group[mean,(11.9±1.5)mm and 15.7°±7.2°]than in the TLIF group[mean,(9.2±2.0)mm and 12.5°±5.9°]at postoperative 2-year(P＜0.001 and P=0.029).The subsidence rate was lower in the OLIF group than in the TLIF group[19.6％(9/46)vs.40.0％(16/40),P=0.037].The fusion rates at postoperative 2-year were 93.5％(43/46)in the OLIF group and 87.5％(35/40)in the TLIF group,having no significant difference(P=0.562).The rates of permanent nerve injury were similar between the two groups[4.3％(2/46)vs.6.7％(3/45),P=0.980]at postoperative 2-year.Conclusion Short segment OLIF doesn't show better clinical outcomes and fusion rate than TLIF for degenerative spondylolisthesis,except for greater disc height restoration,greater segmental lordosis,and lower subsidence rate at postoperative 2-year.
