X-ray morphological features of vertebrae at idiopathic scoliosis of a high risk

Aim: to study anatomic and X-ray morphological changes of vertebrae at patients with idiopathic scoliosis of varying severity with method of a multislice computer tomography (MSKT). Material and Methods. At 27 patients with idiopathic scoliosis of varying severity, the MSKT method studied a condition of vertebrae in chest and lumbar department of a backbone within the continuous, retrospective one-center research. Anatomic and X-ray morphological changes of vertebrae depending on expressiveness of deformation are studied. Results. Results of a research showed that, at more expressed deformation the prevalence of frontal diameter over sagittal is 4-5% more, than at deformation less than 90°. At deformation of a backbone 65-80° vertebra height on the convex party is 22.3±1.7% more, than on concave, at deformation more than 90° the difference made 28.9±2.1 %. The median density of bodies of vertebrae on the convex party was 256.6± 44.7, on convex 267.1±36.2 HU. Patients with size have deformations more than 90°, the maximum density of bodies of vertebrae on the concave party was in 1.1 times more, than from convex, minimum in 2.1 times more, and median by 1.04 times. Conclusions. The anatomy, structure and density of the vertebrae in patients with scoliosis depend on the magnitude of the deformities and are characterized by more pronounced changes with deformities of more than 90°. The maximum changes are noted on the concave side of the scoliotic arch and are manifested by an increase in the maximum and median density of the vertebrae and the presence of areas with a lower density than on the convex side.
