Comparison of the Effects of Transforaminal Lumbar Interbody Fusion and Posterior Lumbar Interbody Fusion on the Treatment of Multi-level Lumbar Spinal Stenosis
Objective:To explore the effects of TLIF and PLIF in the treatment of multi-level lumbar spinal stenosis.Methods:A total of 120 patients with multilevel lumbar spinal stenosis admitted to the hospital from April 2016 to April 2020 were selected and divided into two groups according to surgical methods.62 patients received TLIF,and the remaining 58 patients received PLIF.The operation/hospital stay,incision length,intraoperative blood loss,VAS,ODI,intervertebral space height and complications were compared between the two groups.Results:Compared with PLIF group,TLIF group had smaller incisions,shorter operation/hospital stay,and less intraoperative blood loss(t=19.439,5.128,12.217,9.524;P＜0.05).There were interaction effects among time factors and grouping factors of VAS score,ODI,and intervertebral space height(F=4.872,4.438,3.890;P＜0.05).The overall comparison of VAS score,ODI and intervertebral space height between the two groups showed grouping effect,with statistically significant difference(F=9.571,5.490,6.129;P＜0.05).VAS score,ODI and intervertebral space height had time effects at different time points before and after surgery,with statistically significant difference(F=2 773.355,1 554.785,500.750;P＜0.05).At 6 months after operation,the VAS score and ODI of TLIF group were lower than PLIF group,with statistically significant difference(F=5.654,5.869,5.687;P＜0.05).12 months after operation,there was no significant difference in VAS score,ODI and intervertebral space height between the two groups(F=1.729,1.253,1.496;P＞0.05).The incidence of complications 12 months after operation in TLIF group was lower than PLIF group(χ2=3.928,P＜0.05).Conclusion:Both PLIF and TLIF can effectively improve lumbar function and relieve pain in patients with multilevel lumbar spinal stenosis,but TLIF has quick recovery,less surgical trauma and fewer postoperative complications.
