[Effect of certain professions on the structure of the cervical portion of the spine].

The roentgen-anatomical study of the cervical portion of the vertebral column (fluorography and roentgenography in 2 projections followed by morphometrical treatment) was performed in 603 representatives of different professions: turners, milling-machine operators, craftsmen, mechanicians, jugglers, engineers and constructors. The following facts were established: asymmetry of bodies CIV and CV of vertebra in turners and milling-machine operators; differently pronounced cervical lordosis in persons of different professions; specific features in the architectonics of the spongy substance of the cervical vertebra bodies.
