Spinopelvic parameter consists of sagittal vertical axis (SVA), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS) which are measured by whole-spine-lateral-view radiograph in standing position. Measurement of the separameters is pivotalas the land mark analysis toachieve correct sagittal balance. The objective of the study is to analyze the correlation between PI, PT, SVA and SS with the clinical outcomes which was measured using Oswestry Disability Index (ODI) scoring system.This is a cross-sectional study involving 19 patients who underwent thoracal and lumbar fusion surgery in our centerduring 2012-2014. Radiographi cevaluation of SVA, PI, PT, and SS and ODI score were performed 1 year after surgery. Pearson test was conducted to determine the correlation between SVA, PI, PT, and SS with ODI score.There wasa strong correlation between ODI withSVA and PI (p<0.001,r=0.866; p=0.006; r=0.603, respectively). There was no correlation between other parameters with ODI.Based on this study, spinopelvic parameters that can represent the clinical outcome after thoracal and lumbar fusion and stabilization surgeries are SVA and PI.
