title: [The shape of the thorax based on data of fluorographic studies].
abstract: Five thoracic types were distinguished on the basis of 3 transverse sizes between the 4th, 7th, and 10th ribs, detected on the thoracic fluorograms of 1116 men and 1460 women: cylindrical, narrow conical, conical, wide conical, and egg-shaped. A subtype of a cylindrical thorax--cylindrical with a waist--was distinguished in women. In men conical chests occurred in 48.9% of cases, wide conical in 24%, whereas in women narrow conical chests occurred in 41.8% and cylindrical in 27.5% of cases. The examinees were grouped in accordance with the thoracic shape and their physical parameters and the parameters of the chests were compared. The chest proportions represent the most comprehensive characterization of the skeletal index: the ratio between the transverse size between the 7th ribs and the vertical size in per cent. The skeletal index directly correlates with body mass, thoracic circumference, transverse and longitudinal sizes of the heart and is in inverse correlation with body length, angle of inclination of the 8th rib and angle of inclination of the heart axis to the horizontal line.
