AbstractAnalysis of the individual components of the vertebrae permits the radiologist to identify and understand the fundamental physio-pathologic growth mechanisms affecting shape, size and architecture which operated during development. The achievement of this goal is facilitated by systematically paying attention to changes of the vertebral end-plates, anterior and posterior aspects of the vertebral body, the vertebral rim, neurocentral junction and interpedicular distance. The dynamic changes noted in followup studies of the spine in certain dysplasias may reveal the developmental history of the vertebral complex. The dimension of time is an important factor, which the radiologist has a unique opportunity to exploit. Vertebral configuration permits radiological analysis and diagnosis.
