384 victims aged 1 to 14 years with damages of middle and distal hand parts were examined. The rate of osteo-epiphysiolysis, hand damages without affection of zone of growth in different short bones of hand is presented. Significant group of damages is composed of subperiosteal fractures and osteo-epiphysiolysis. Special features of different types of osteo-epiphysiolysis and roentgenologic signs which differ them from juxta-epiphyseal fractures are described. Of special significance in diagnosis of osteo-epiphysiolysis is the "bone lamina" sign and uneven expansion of the zone of growth.

X-ray examinations by a traditional method in 694 patients with non-complicated compression fractures in the thoraco-lumbar part of the vertebral column do not always give the exact picture of the character of fractures of the vertebral column. The method of optic processing the roentgen picture was used in 30 patients for more detailed analysis of structural changes in the vertebrae bodies. The method allowed to specify structural changes in the vertebra bodies, including the detection of the fracture plane, abruption of a body portion, detection of an additional contour of the limiting plate in its pressing into the vertebra body and the zone of infiltration in the upper portions of the body.
