Differences in pelvic parameters among Mexican, Caucasian, and Asian populations.

Object: The aim of this study was to describe the pelvic parameters in a sample of healthy Mexican volunteers and to compare them with previously reported data for Caucasian and Asian populations.

Methods: This was a transversal study that included a sample population of healthy Mexican volunteers. Age, sex, and lateral radiographs of the lumbosacral region with the individual standing to obtain the pelvic parameters of pelvic tilt (PT), sacral slope (SS), pelvic incidence (PI), and lumbar lordosis (LL) were recorded in each volunteer.
