Included or excluded pelvis – does the inclusion of the pelvis in the scoliotic process influence the outcome?

Background Even though scoliosis is principally a deformity of the spine and the rib cage, some authors demonstrated that the pelvis can be included in the scoliotic process. Bernard Bricot concluded that the patients that presented with an excluded pelvis have a more evolving scoliosis. With regards to the pelvis we have two categories: the pelvis is excluded or included in the scoliotic process. In the first case the pelvis should be perfectly balanced, where as in the second group we can find a tilt, torsion or rotation of the pelvis. The purpose of this retrospective cohort study was to verify if the inclusion of the pelvis has an influence for the outcome of the treatment.
