The article presents data on the state of the paravertebral muscles studied by magnetic resonance imaging (MRI) in 26 patients with idiopathic scoliosis with various degrees of spinal deformity. A decrease in muscle area and fatty degeneration, expressed from the concave side, were noted. The area of the paravertebral muscles on the concave side in deformity of 70–90 ° significantly differed from the area of the muscles on the convex side. The average degree of fat infiltration of various muscles along the concave side ranged from 14 to 28 %. The degree of fatty degeneration and hypotrophy of the paravertebral muscles should be taken into account when preparing for surgery, during its performance and when developing a rehabilitation program in the postoperative period.

“…Исследования паравертебральных мышц у пациентов с ИС демонстрируют структурные изменения и асимметрию строения мышц, что может либо вызывать сколиоз, либо быть вызвано сколиозом. Морфологические изменения в мышцах при ИС носят преимущественно неспецифический диффузный характер [76,77], а асимметрия работы параспинальной мускулатуры подтверждается данными ЭМГ [78,79].…”

Objective. To analyze the current literature dedicated to the etiopathogenesis and development of idiopathic scoliosis.Material and Methods. The analysis includes studies on the etiological factors of idiopathic scoliosis. The search was carried out on eLibrary, PubMed and Google Scholar databases. The review includes research and experimental studies, as well as systematic reviews and meta-analyses. The exclusion criterion is a theoretical work without practical research/experiment to confirm the theory. The depth of analysis is 30 years.Results. Out of 456 papers on the research topic, 153 were selected as meeting the inclusion/exclusion criteria. The main theories of the occurrence of idiopathic scoliosis are identified: genetic, neurogenic, theory of bone and muscle tissue defects, biomechanical, hormonal, evolutionary, and the theory of environmental and lifestyle influences.Conclusions. The term “idiopathic scoliosis” combines a number of diseases with different etiopathogenetic mechanisms of development. Idiopathic scoliosis has a polygenic inheritance. Different genes are responsible for its occurrence in different populations, and the progression mechanisms are triggered by various epigenetic factors. Bone and muscle tissue defects, pathology of the central nervous system, biomechanical disturbances, hormonal and biochemical abnormalities may play a dominant role in some cases of idiopathic scoliosis.

ВACKGROUND: For the treatment of degenerative diseases of the spine, various deformities, a minimally invasive technique of lateral lumbar interbody fusion is used, which minimizes the risks of spinal cord injury. In the development of these pathologies, the most important role is assigned to the paraspinal muscles, the histological features of which are insufficiently elucidated in the relevant literature when modeling spondylodesis. АIM: To investigate the effect of lateral interbody vertebral fusion (spondylodesis) when introducing titanium implants on the histostructure of the psoas minor muscle. МATERIALS AND METHODS: Experiments were performed in 14 mongrel dogs, 3 individuals the control group (norm). The аnimals underwent discectomy at the level of L45, L56 vertebrae through the lateral approach on the right, and interbody titanium implants were installed. The lumbar spine was stabilized with an external fixator for 30 days. Paraffin muscle sections were stained with hematoxylin-eosin, according to Masson. RESULTS: During the experiment, an increased variety of myosymplast diameters, loss of polygonality of their profiles, fibrosis of the interstitial space, and sclerotization of the vascular membranes were observed in the psoas minor muscle. The volume density of endomysium in both muscles increased 1.5 times relative to the norm after 6 months Other parameters decreased: the volume of myosymplasts was 95%, that of microvessels 73% on the left, 83% on the right. On the other hand, the degree of fatty infiltration increased, amounting to 276% on the left and 394% on the right of the normal parameters. After 18 months, the bulk density of muscle fibers on the left was restored to the value in the control, on the right it was only 95%. The degree of sclerotization in the muscle on the left is 133%, on the right 161% of the norm; the index of fatty infiltration was 146% on the left and 339% on the right of the normal parameter. CONCLUSION: pathohistological changes in the psoas minor during lateral interbody fusion are more pronounced on the side of the operative approach, which necessitates minimizing trauma to the paravertebral muscles during operations in order to prevent sclerotization and fatty involution of muscle tissue.
