Objective: To define the sagittal balance and spinopelvic parameters in a Brazilian population sample composed of asymptomatic volunteers. Methods: Fifty healthy adult individuals volunteered to participate in this study. The exclusion criteria included spinal deformity or improper radiograph study. In each radiograph exam in profile view, the sagittal balance and spinopelvic parameters were evaluated, including vertical sagittal axis, sacral slope, pelvic tilt and pelvic incidence. Results:

None of the radiographic parameters showed any differences between the genders. Comparing the values presented in this study with those of other reports, with different populations, it was observed that: there was no significant difference in any of the pelvic parameters between Brazilian and Korean populations; there was a significant difference in pelvic incidence between Brazilian and European populations in a total sample (p=0.0001), in males (p=0.02), and in females (p=0.0007); there was a difference in sacral slope between Brazilian and European populations in a total sample (p=0.0140), and in females (p=0.005). Conclusion: There were no differences in any parameter in terms of gender. There were no differences in pelvic incidence between Brazilian and Korean populations. There was a difference in pelvic incidence between Brazilian and European populations, in the total sample and in males and females. There was a difference in sacral slope between Brazilian and European populations in a total sample, and in females.
