The Clinical Outcomes Of Patients With L1-L2 Disc Herniation Treated By Microsurgical Trans Facet Approach

Abstract

Background: In comparison to lower lumbar disc herniation, L1-L2 disc herniation has unique characteristics, which cause controversy in selection of surgical approach. The goal of this study was to evaluate the clinical outcomes for treatment of L1-L2 disc herniation by microsurgical transforaminal lumbar interbody fusion (TLIF) technique. Therefore, 37 symptomatic patients of L1-L2 disc herniation who were treated by TLIF, from 2008 to 2016, in three academic hospitals were reviewed retrospectively. Follow-up of these patients should significant clinical improvement following TLIF surgery (p-value <0.001) and acceptable bony union with respect to the results, we concluded that TLIF can be an effective, reproducible and safe technique for surgical treatment of L1-L2 disc herniation.
