FIELD: medicine.SUBSTANCE: body base plane is preliminary fixed by attaching marks on left and right apexes of anterior superior iliac spines and in a lower point of suprasternal notch; left and right acromioclavicular joints are also marked. After body scanning, bone guide marks are identified on apparatus projection of front and lateral images, and the image projections are plotted by transferring the apparatus projections on the body base plane taking into account mark positions in relation to the apparatus planes. Deformities arcs are marked on the spinal projections to determine thereby a curvature of actual (3D) spinal arcs by formula[m], wherein Rand Rare average radiuses of deformities arcs on the spinal projections, and an plane inclination ?° of the actual (3D) arc to the frontal base plane is calculated by formula: ?° = arctg[(h)]/(h)], wherein hand hare heights of the average arcs of the spinal projections. The measurement results make it possible to assess the derived values: a thoracic or thoracolumbar deformity is considered as lordoscoliosis if ?° = 0°-20°, as scoliosis if ?° = 21°-45°, as kyphoscoliosis if ?° = 46°-70°, as kyphosis if ?° = 71°-90°; a lumbar deformity is considered as lordosis if ?° = (-71°)-(-90°), as lordoscoliosis if ?° = (-46°)-(-70°), as kyphosis if ?° = (-21°)-(-45°), as kyphoscoliosis if ?° = 0°-(-20°), whereas a degree of scoliosis is determined by applying a topographic technique to experimental diagrams in coordinates K-?°. If the patient suffers a torsion deformity with a greater curvature, the spine is examined by fragments - for each movable segment, whereas a general spinal health statement is passed on the basis of extreme, average and integral estimates of a series of arc segment measurements.EFFECT: method provides higher accuracy of the assessment of pathological spinal deformities taking into account specific characteristics of the current body health.4 dwg, 1 ex |
