The results of the lumbar spine examinations performed in one year and a half are evaluated by the authors. The types of the sagittal positional changes of the vertebral bodies are discussed in detail. The importance of the functionally centrated and lateral telephotographs in the diagnosis of the antepositional olisthesis and the retropositional retrolisthesis is pointed out, and the indication and the differential diagnostical value of the oblique roentgenograms are dealt with.
