Spinopelvic Alignment in Subjects With Down Syndrome

Study Design: This was a cross-sectional study. Objective: The aim of this study was to describe the spinopelvic alignment of subjects with Down syndrome (DS). Summary of Background Data: Subjects with DS are known to suffer from a large prevalence of scoliosis. While scoliosis is known to significantly affect postural alignment, there are currently no studies on the spinopelvic alignment of subjects with DS. Materials and Methods: In total, 41 subjects (28 female subjects and 13 male subjects) with DS, age and sex-matched to 41 asymptomatic subjects, underwent biplanar x-rays with 3-dimensional reconstructions of their spines and pelvises, followed by measurement of commonly used spinopelvic sagittal and coronal alignment parameters. Subjects were then classified into one of Roussouly’s 4 types of sagittal alignment. Alignment parameters and prevalence of alignment patterns were compared between the 2 groups. Results: Subjects with DS were found to be relatively hypokyphotic (T4–T12=−29.0 vs. −37.5 degrees; P
