The purpose of the study is to describe features of the surgical technique for correction of kyphotic deformity of the spine and to analyze the results of surgical treatment of juvenile kyphosis in children with the use of 3D-CT navigation. Materials and methods. We observed 11 patientsaged 14-17 years old (2 girls and 9 boys) with kyphoticdeformity of the spine, developed on the backgroundof Scheuermann’s disease. The deformity amount aver-aged 73,9° (60 to 90°). Surgery was performed fromthe combined access, carring out discapophysectomyand corporodesis on top of kyphosis and fixing mul-tibasic corrective metal construction. For the insertionof pedicle screws we used 3D-CT navigation. The results. After surgery kyphosis value decreasedto 32,6° (20 to 45°), the deformity correction averaged41,3° (30 to 50°). Hybrid systems were placed in 5 pa-tients, total transpedicular fixation - in 6 children.Number of fixed vertebrae with hybrid metal construc-tions averaged 14 (13 to 15), in patients with total pediclefixation - 13 (12 to 14). In all cases we observed the correct position of pedicle support elements. Postopera- tive follow-up period was from 1 year and 5 months to5 years and 4 months, on average - 3 years 5 months. The loss of the result achieved in the long-term follow- up period was observed in patients with hybrid metal constructions and averaged 7,2° (4 to 9°). Conclusion. The use of pedicle screws for thecorrection of juvenile kyphosis in children allows forthe effective correction of the deformity, restoring thephysiological profiles of the spine, eliminating post-operative progression of curvature, and reducing thelength of metal fixation and save the result achievedin the long-term follow-up. The use of active optical3D-CT navigation allows carring out a correct inser-tion of pedicle screws in the vertebral bodies in chil-dren with juvenile kyphosis.
