High values of pelvic incidence: A possible risk factor for zigoapophyseal facet arthrosis in young.

In humans the acquisition of the bipedalism caused different structural changes to achieve the new functional demands. In particular, several changes have occurred in the spine and pelvis. In recent years the sagittal morphology of the spine and pelvis has become one of the most focused topics in spine research.

Finite element analysis of sagittal balance in different morphotype: Forces and resulting strain in pelvis and spine.

In humans, vertical posture acquisition caused several changes in bones and muscles which can be assumed as verticalization. Pelvis, femur, and vertebral column gain an extension position which decreases muscular work by paravertebral muscles in the latter. It's widely known that six different morphological categories exist; each category differs from the others by pelvic parameters and vertebral column curvatures.
