FIELD: medicine. SUBSTANCE: method involves measuring circle arc radius R on vertebra X-ray picture that coincides with vertebra body middle part outline on its maximum length segment and central angle n subtended by the arc of the same circle. The coefficient of K is calculated from formula , where K describes intravital vertebra body deformity. Its value being less than 0.147 ± 0.013 mm for LIII, increased compression load acting upon the vertebral column is to be determined in 25-50 years old male patients. EFFECT: enhanced accuracy in determining functional characteristics of the vertebral column and permissible loads to be applied. 1 dwg, 1 tbl
