Objective: Knowing the volumetric and morphometry properties of lumbar vertebrae and discus intervertebralis is important to achieve a successful approach to degenerative disc diseases. In this study, we aimed to compare the heights of intervertebral discs and concavity index values in patients with disc herniation and Mr images of healthy cases and also the corpus of lumbar vertebrae and the volumes of intervertebral discs in patients with disc herniation according to age and gender. Methods: Changes in the concavity index of discus intervertebralis were recorded in order to evaluate the differentiation in lumbaric lordosis. The control group consisted of 50 (25 women and 25 men) lumbar disc hernias with age range 18–75 (20 women and 20 men). In both groups, the volume of the disc was evaluated by using the Cavalier method. The concavity index was evaluated as the ratio of central disc height (c) to anterior disc height (a). Increased concavity index (C/a) ratio was evaluated as reduction/flatness in lumbar lordosis. Results: It was found that age-related degeneration and loss of volume due to dehydration occurred in the disc compared to healthy disc herniation cases. Conclusion: The morphometric evaluation of discus intervertebralis and the concavity index of lumbar lordosis were calculated and revealed in cases with disc hernias due to age and gender, both radiologically and clinically, we anticipate that the diagnosis and treatment will provide a clue.
