METHOD FOR PREDICTING SCOLIOTIC VERTEBRAL DEFORMATIONS Russian patent published in 2007 - IPC A61B5/103 

FIELD: medicine, traumatology, orthopedics.

SUBSTANCE: the present innovation could be applied in clinical practice and in the course of research trials for solving diagnostic tasks and planning the type of therapy. The innovation suggested should be carried out due to measuring the value of deformation arch, moreover, one should apply vertebral investigation with the help of a scanner. For describing the scoliotic arch one should mark the points of acromial-clavicular symphyses, anterior superior and posterior superior iliac spines, the points along vertebral column along the line of spinous processes of cervical, thoracic and lumbar departments of vertebral column that characterize the shape and spatial orientation of vertebral column in three dimensions. One should evaluate the parameters obtained: in sagittal plane at the values of sagittal contour being below 20° one should diagnose lordoscoliosis, above 40° - kyphoscoliosis. In horizontal plane at the values of the turn of brachial girdle and pelvis being below 5.2° one should diagnose unstructural scoliosis, above 5.2° - structural scoliosis. In frontal plane at the values of central angle being above 0° one should diagnose scoliosis, below 5° - subcompensated scoliosis, above 5 - decompensated scoliosis, at negative values of central angle of the arch one should diagnose right-hand scoliosis, at positive - left-hand scoliosis, at localization of scoliotic arch from Th₁ up to Th₁₂ one should diagnose thoracic scoliosis, at localization of scoliotic arch from L₁ up to L₅ - lumbar scoliosis, in case of one arch one should diagnose C-shaped scoliosis, at two equal arches - S-shaped scoliosis, at predominance of one arch being above another one should diagnose the arch with contra-curvature, at mobility of scoliotic arch being below 30% one should diagnose rigid scoliosis, above 30% - mobile scoliosis, at the value of scoliotic arch ranged 1°-10° one should diagnose I-degree scoliosis, 11°-25° - II-degree scoliosis, 26°-50° -III-degree scoliosis, above 50° - IV-degree scoliosis. Based upon the obtained parameters one should form the diagnosis of scoliotic deformations of vertebral column. The innovation enables to increase the accuracy of segment-by-segment measurements of vertebral deformation and, also, detect spatial orientation of vertebral column in three dimensions and obtain automatized total clinical diagnosis.

EFFECT: higher accuracy of diagnostics.
