Inclusion criteria consisted of symptomatic patients with hip dysplasia undergoing 2-dimensional radiography as well as computed tomography. On radiography, the lateral center edge angle, acetabular hip index, hip lateralization index, acetabular index angle, and the Sharp angle were measured, and the presence of a crossover sign was noted. In computed tomography, the full rotational profile of the lower limb was measured.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Significant correlations were observed in the overall analysis between the anteversion of the acetabulum and the hip lateralization index (mean 0.56, coefficient of regression (CoR) \u221232.35, <jats:italic>p<\/jats:italic> = 0.011) as well as the acetabular index angle with a mean of 11.50 (CoR 0.544, <jats:italic>p<\/jats:italic> = 0.018). Similar results were found in the subgroup of dysplastic hips with an acetabular index angle of 13.9 (<jats:italic>p<\/jats:italic> = 0.013, CoR 0.74).

For borderline-dysplastic hips, such results did not show up, which strongly illustrates the need for computed tomography in these cases.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Key Points<\/jats:title>\n                <jats:p><jats:italic>\u2022 Much of the current literature focuses on rotational alignment especially with respect to the femur and tibia in healthy patients, although little is known about the acetabular, femoral, and tibial torsion in dysplastic hips.<\/jats:italic><\/jats:p>\n                <jats:p><jats:italic>\u2022 This is the first study showing significant correlations between the anteversion of the acetabulum and the hip lateralization index as well as the acetabular inclination angle.
