This dissertation is devoted to improving the results of acetabular dysplasia surgical correction in developmental dysplasia of the hip after the application of pelvic reconstructive osteotomies in patients younger than 6 years. The results' improvement is planned to be implemented by conducting a meta-analysis of the results after the application of pelvic osteotomies and analyzing the risk factors of these surgeries; assessment of acetabular three-dimensional morphology in children younger than 6 years, taking into account age and gender; mathematical and experimental modeling of pelvic osteotomies in 2- and 6-year-old patients; a description of the modified Salter pelvic osteotomy, which may improve femoral head coverage in all directions; comparison of postoperative results after the application of modified technique and classically described one. The scientific novelty of the work is: for the first time, the impact of a patient's age and acetabular deformity degree on long-term clinical and radiological results was determined; gender differences in three-dimensional acetabulum morphology in children younger than 6 years were proven; biomechanical changes during Salter, Dega and Pemberton osteotomies in 2- and 6-year-old children were investigated; experimentally bone changes during Salter, Dega and Pemberton osteotomies were evaluated, taking into account animal's age. The practical significance of the work is: risk factors leading after the application of Salter, Dega and Pemberton osteotomies are determined; the inexpediency of applying the same or a combination of two different pelvic osteotomies at the same time on both sides is substantiated; a methodology for evaluating the three-dimensional acetabular morphology was developed, this methodology enables to compare the extreme variants of the normal acetabulum development with the initial manifestations of its deformation; modified Salter pelvic osteotomy was described, which is able to improve the femoral head coverage in all directions, its advantages were assessed in comparison with the classically described technique.
