Idiopathic scoliosis, as many authors think, being idiopathic in terms of not fully clear etiology of the disease, due to the most complicated long-term studies, has a certain theory of the pathogenesis of scoliosis, which includes the disharmony of the longitudinal growth of the spine and spinal cord and the formation of vertebral torsion. The app...
