ABSTRACT Objective To evaluate the correlation between global sagittal alignment variables and pain improvement after surgery for High-Grade Spondylolisthesis (HGS). Methods A sample with 20 patients with L5-S1 HGS, submitted to arthrodesis with instrumentation from 01/2004 to 12/2016. Patients’ demographic data, types of surgeries, complications, sagittal alignment parameters, and Visual Analog Scale (VAS) score (ranging from 0 to 4) were recorded before surgery and at the last follow-up. The data were processed in SPSS 22.0. The confidence level was 0.05. Results The majority of the sample were women, 17 (85%); age at surgery: 52.60 ± 17.15 years; mean follow-up: 3.58 ± 1.62 years; isthmic etiology, 16 (80%) and dysplastic, 4 (20%); Meyerding Grading 3: 12 (60%), Grading 4: 3 (15%) and Grading 5: 5 (25%); SDSG type 4: 6 (30%), type 5a: 3 (15%), 5b: 3 (15%), type 6: 7 (35%) and not classified 1 (5%); surgery: in situ fusion 3 (15%) and reduction 17 (85%); fusion levels: L3-S1: 1 (5%), L3-Iliac: 1 (5%), L4-S1: 1 (5%), L4-Iliac: 6 (30%) and L5-S1: 11 (55%). Comparing the pre- and postoperative parameters, a significant improvement (p <0.05) was seen in the VAS, T1 slope, T1 pelvic angle (TPA), slip angle, Dubousset’s lumbosacral angle and slip %. Evaluating the correlation between the variation in sagittal parameters and the improvement in VAS scale, it was found that the TPA showed a strong correlation (r = 0.709, p = 0.032). Conclusions the present study found a strong correlation between the improvement/reduction in TPA values and the reduction in pain intensity in the VAS. Level of evidence IV; Case Series.
