In the newborn and young infant the vertebral bodies, although basically rectangular, often appear more oval because they have rounded corners, especially anteriorly (Fig. 2.1A). Thereafter the vertebral bodies become more cuboid-rectangular (Fig. 2.1B), but in some individuals can appear exceptionally flat (Fig. 2.1C). This latter configuration is not to be misinterpreted as being representative of platyspondyly, as seen with bony dysplasias, for it merely reflects the wide spectrum of the normal appearance of the vertebral bodies.
