Secondary (compensation) curves: lumbar and cervical: appear several months after birth, abnormal curvatures of the spine, kyphosis, hunchback, dramatic effect in the thoracic curvature of the spine. Can be caused by difference in thickness between the anterior and posterior parts of the intervertebral discs (the disc is not uniformly sized throughout the body), pregnancy or excessive weight gain. Exaggerated lateral curvature: quite common in girls. Can be caused by injury or usually caused for unknown causes.
