Spinopelvic parameters evaluation in a Brazilian population sample.

ABSTRACT

INTRODUCTION: The morphology of the spine is variable within a population, and its maintenance in appropriate values implies a decrease in the energy expended. We need to know their normal values in population. This study aims to carry out a literature review and evaluate published papers on spinopelvic parameters in a Brazilian population sample. METHODS AND POPULATION Eleven potentially eligible papers were initially identified for inclusion in this review three papers from PubMed and eight from Medicine. Out of these, only five papers contained methodology and relevant significance level, and therefore, they were included in the final analytical run. DISCUSSION: According to a Brazilian study, Pratali mentions no significant difference in the average values of spinopelvic balance in the Brazilian population and those found in the literature; there was also no significant difference comparing Brazilian and Korean population; however, a difference was found in comparison with European population regarding PI parameters and SS, but the latter with higher values. According to Kulcheski (Column/Columna 12224-227, 2013), the values of pelvic tilt in the Brazilian population evaluated in his research were 19° (10°-35°) and the sacral inclination was 38° (30°-55°), presenting similar values concerning the European population. In another Brazilian paper, Oliveira (Rev Bras Ort 49189-193, 2014) reports that the research population had PI average of 45° (41.9°-48.1°). CONCLUSION: The values obtained are relatively minor when compared to the European population. However, all of these are within the normal margin considered in the worldwide literature.
