Abstract and keywords

A technique to reposition the spinal column in FE HBM's based on the trunk flexion or pelvis rotation angle is presented in the study. Representation of the spinal posture using natural splines is found to be an effective way of locating the position and orientation of the vertebrae when the spinal column is being flexed. Cobb and inter segmental angles obtained are in agreement to those reported in literature. It is also indicated that in clinical studies, a simplified analysis of radiographs is possible by interpreting the position of only five key vertebrae.
