FIELD: medicine, diagnostics.
SUBSTANCE: ultrasound scanning should be performed in patient's stomach-lying position at frontal support, ultrasound pick-up unit should be located at patient's skin at the level of atlas' posterior tuberculum directly under inferior edge of occipital bone so that scanning area should be parallel to inferior edge of occipital bone; then one should detect the distance between axis' odontoid process and corresponding atlas' lateral weight from the left and from the right to calculate the value of asymmetry, moreover, if the value of asymmetry exceeds 0.6±0.3 mm one should diagnose dislocation of axis' odontoid process. The innovation in question enables to establish accurate site of dislocation of axis' odontoid process without any roentgenological loading and provide quantitative detection of the dislocation mentioned.
EFFECT: higher accuracy and efficiency of diagnostics.
