The paradox of lumbopelvic alignment in anterolateral and posterolateral phenotypes of symptomatic hip dysplasia.

Purpose: The relationship between sagittal lumbopelvic alignment and the bony pathomorphology of hip dysplasia is currently at the forefront of clinical and scientific interest. The aim of this study was to determine whether there is a compensatory lumbopelvic aspect associated with the two major acetabular phenotypes in dysplastic hips.

Methods: From September 2022 to March 2024, a total of 145 patients with symptomatic bilateral hip dysplasia were included in the study.
