SKOLIOZOMETRIYA

From Big Medical Encyclopedia

SKOLIOZOMETRIYa (Greek skoliosis a curvature + metreo to measure, measure) — measurement of extent of deformation of a backbone: its side curvature and torsion of vertebrae (turn round its pivot-center). These measurements are necessary for the choice of a method of treatment, control of its efficiency and establishment of the forecast scoliosis (see).

In the past for a wedge, measurements were offered skoliozometr Mikulich, devices Hit — Kirchhoff, Eler, Zemeleder and Patters, Helst, Deychlender, Gamburtsev's goniometer, etc., to-rye into a crust, time are not used.

Fig. 1. Measurement of degree of a side rachiocampsis by means of a cord plumb (points designated projections of acanthas of vertebrae, by solid lines — contours of the bottom internal corners of shovels and wings of ileal bones): the deviation of acanthas from the line of a plumb demonstrates existence of scoliotic deformation of a backbone.
Fig. 2. Measurement of size of torsion of vertebrae and height of a costal hump by means of Shultees's device: the patient is inclined forward, an emphasis of the device is established paravertebralno, the arrow on a scale of the device shows the size of torsion of vertebrae in degrees (points designated projections of acanthas of vertebrae, by solid lines — contours of the bottom internal corners of shovels).

For definition of degree of a side rachiocampsis the easiest and widespread way is measurement by means of the cord plumb fixed by an adhesive plaster over an acantha of the VII cervical vertebra. The deviation of acanthas from the line of a plumb demonstrates existence of scoliotic deformation of a backbone (fig. 1). The size of torsion of vertebrae and height of a costal hump can be determined in degrees, using Shultess's (fig. 2) device.

Fig. 3. The diagrammatic representation of determination of size of a rachiocampsis on roentgenograms by means of Ferguson (a) methods and Kobba: and — through the centers of neutral vertebrae (extreme in an arch of a curvature) and the center of a vertebra at top of an arch of a curvature straight lines, a corner and between which reflects the size of a rachiocampsis are drawn; — along edges of bodies of neutral vertebrae two straight lines to which the perpendiculars at a crossing forming a corner and a rachiocampsis are recovered are drawn.

Rentgenol. measurements allow to receive not only an overall picture of a rachiocampsis, but also a detailed information about deformation at various levels of the bent segment of a backbone. For determination of size of a rachiocampsis on the basis rentgenol. pictures many methods are offered; Ferguson's methods and Kobba are most widely used. Ferguson's method (fig. 3, a) is based on identification of 3 points of an arch of a curvature: 2 points corresponding to the centers neutral (extreme in an arch of a curvature) vertebrae, the 3rd, belonging to the center of the vertebra which is at top of an arch of a curvature. Crossing of the lines drawn through these points forms a corner, to-ry and reflects the size of a rachiocampsis. During the definition of a corner of a curvature across Kobbu (fig. 3, b) draw a line along top and bottom edges of bodies of neutral vertebrae. The corner between the perpendiculars recovered to these two lines corresponds to a corner of a curvature.
