Classification of Coronal Spinal Deformities Associated with Pelvic Tilt in Children and Adolescents Evidenced by Computer Optical Toрography

Objective. To study possible combinations of spinal deformities in coronal plane associated with pelvic tilt in children and adolescents and create the working classification based on findings of the computer optical tomography. Material and Methods. Computer optical tomography method was used for examination of 623 patients with pelvic tilts of more than 1.5° inducing coronal spinal curvatures such as functional and compensatory scoliosis, and grade I and II structural scoliosis. Results. Detected forms of coronal curvatures associated with pelvic tilt are distributed into five types depending on topographical criteria based on quantitative evaluation of pelvic tilt (1.5° and more), maximum lateral deviation of the line of spinous processes (2 mm and more), level of the curvature apex (not above T6), and the tilt of the trunk’s longitudinal axis (1.5° and more). Conclusion. The suggested classification of coronal spinal curvatures associated with pelvic tilt could help a practicing orthopedist to choose individual treatment algorithm and rehabilitation actions for each patient. Proper treatment produces good results in patients with non-surgical forms of coronal spinal curvatures induced by pelvic tilt.
