Changes in Radiographic Parameters After Minimally Invasive Lumbar Interbody Fusion
Abstract: Objective : This study aims to evaluate changes in lumbosacral parameters after minimally invasive lumbar interbody fusion. The secondary aim was to evaluate whether interbody cage shape (crescent shaped or rectangular) would influence the results. Method : Retrospective analysis of 70 patients who underwent one or two level lumbar interbody fusion through a minimally invasive posterolateral approach. This included midline preservation and unilateral facetectomy. Pre- and postoperative (three to six months po…

“…Considering the improvement in sagittal alignment because of the gain in lordosis, maybe we should perform bilateral facetectomies and, perhaps, more aggressive discectomies. 3 In contrast to our findings, the literature shows that the anteroposterior positioning of the cage regarding the disc space has no direct influence over postoperative lumbar lordosis. For Faundez et al, 11 neither positioning (TLIF-A and TLIF-P) could change the final SL, since the unilateral TLIF technique keeps the anterior and posterior longitudinal ligaments intact.…”
