[Quantification of physiological kyphosis adults according to the roentgenogramometry data]

The shape of thoracic physiological kyphosis was studied based on data obtained through the examination of 120 patients who had presented no complaints regarding thoracic spine. As a result, a quantitative description of a normal curvature for thoracic kyphosis was elaborated. The study addressed such issues as the impact of separate segments on the development of kyphosis, with the identification of relevant quantitative parameters. In addition, sex-related differences of the quantitative parameters describing the form of thoracic spine were determined. The study analyzed tendencies in the curvature transformation during the life period of 16-30 years of age.
