METHOD FOR DIAGNOSING PROTRUSION OF INTERVERTEBRAL DISCS OF CERVICAL BACKBONE DIVISION IN THE CHILDREN

摘要

The method for diagnosing protrusion of intervertebral discs of the cervical backbone division in the children is performed by sonographic visualization at C3-C7 level. The ratios between the sagital size of intervertebral disk (IVD) and backbone canal (BC), anterior and posterior dural space (ADS/PDS), and ADS/BC are measured. The echogenicity of the pulpous nucleus, its non-homogeneity and its shift are assessed, the echogenicity of the fibrous ring, its thickness and non-homogeneity and the extent of its protrusion are assessed, the anterior-posterior distance of the radicular canal is measured. The medical protrusion is diagnosed in the case of the overt protrusion of the posterior outline of IVD beyond the horizontal line (by more than 3 mm) with the deformity of the anterior dural space that is not visualized distinctly with the integrity of the thinned fibrous ring, ADS2.0 mm in sagital projection, ADS/PDS0.6, ADS/BC0.2, IVD/BC1.1. Paramedian protrusion are such as follows: local extension of the disk beyond the horizontal line tangential to its posterior outline by more than 2 mm, asymmetry of the anterior dural space and BC, partially - radicular canals. The signs of posterior-lateral protrusion are the narrowing and the over asymmetry of radicular canals by more than one third of their anterior-posterior size.
