Graphic representation of a pathological spine according to the spinal Top View and its correspondence with the 3D real spine. Spinal Top View: projection on to the horizontal plane of the spine morphology. Barycentre: barycentre of the points reconstructing the spine projected in the horizontal plane. Antero-posterior (AP) spinal axis: projection on to the horizontal plane of the 3D linear regression of the markers on the spinal apophyses of the spine. Latero-lateral (LL) spinal axis: the axis orthogonal (90°) to the AP spinal axis passing through the barycentre. Area: the surface area limited in the horizontal plane by the Top View.
