ABSTRACT

In preserving the vertical position of a healthy person, paravertebral muscles have a special role, but pathogenic importanceis attached to these muscles in the development of deformity of the most important segment of the spinal column.From this point of view, early diagnosis of the anatomical and functional state of these muscles is extremely relevant. Today,the main way to assess the functional state of the muscular system is electromyography. However, this method does notallow to evaluate the macrostructure of these muscles. In this case, the method of ultrasound diagnostics, as non-invasive,affordable, low-cost and fairly informative, in our opinion is optimal. For further study of pathology, it is necessary to clarifythe concept of the norm. At the clinical base of the Saint-Petersburg Children’s Rehabilitation Center of Orthopedics andTraumatology «Ogonyok» 30 children from 9 to 11 years old were examined without clinical and instrumental signs of scoliosisand poor posture. In all patients, the evaluation of the paravertebral muscles was performed in the supine and standingposition, on the right and on the left side. For the study, a linear sensor with a frequency of 5–10 MHz of the Aloka SSD-1100ultrasound scanner was used. Studied the cross-sectional area of the muscle and its density. As a result of the study, objectivedata were obtained for the symmetry of the cross-sectional area and the echo density of the paravertebral muscles of themedial tract in the lumbar region between the right and left sides in healthy children, both in the standing position and inthe prone position. The obtained data give an idea of the normative parameters in the diagnosis of paravertebral muscles,which is necessary for working with patients with spinal deformity.

KEYWORDS: AIS, pathogenesis, paravertebral muscles, ultrasound diagnosis, muscle density, muscle cross-sectional area, prediction of progression of spinal deformity.
