Vertebral rotation was systematically analyzed in the normal, nonscoliotic thoracic spine of children aged 0 to 16 years. Subgroups were created match infantile, juvenile, and adolescent age groups according criteria Scoliosis Research Society.To determine whether a distinct pattern vertebral transverse plane exists spine.We assume that, once starts deteriorate into scoliotic deformity, it will follow preexisting rotational pattern. Recently, we identified normal adult that corresponds most common curve types idiopathic scoliosis. In infantile scoliosis, curves are typically left sided boys affected more often than girls, whereas is right predominantly girls affected. The present study first systematic analysis children's spine.Vertebral T2-T12 measured by using semiautomatic method on 146 computed tomographic scans (0-16 years old) without clinical or radiologic evidence spinal pathology. Scans mainly made for reasons such as recurrent respiratory tract infections, malignancies, immune disorders. patterns (0-3-year-old), juvenile (4-9-year-old), (10-16-year-old) girls.In spine, vertebrae T2-T6 significantly rotated (P < 0.001). T4 left. T6-T12 ≤ Rotation pronounced = 0.023). children, no statistical differences found between sexes.These data support hypothesis direction scoliosis determined built-in exhibits at time onset. well-known predominance right-sided left-sided can be explained observed preexist corresponding age.
