However, uniplanar skiagrams are unable to render real spatial configuration of the femoral bone. When combining three-dimensional and uniplanar models of bone, human errors inevitably occur, causing the distortion of preset parameters, which may lead to glaring errors and, as a result, to repeated operations.</p><p><strong>Aims.</strong> To develop a new three-dimensional method for planning and performing corrective osteotomy of the femoral bone, using visualizing computer technologies.</p><p><strong>Materials and methods.</strong> A new method of planning for corrective hip osteotomy in children with various hip joint pathologies was developed. We examined the method using 27 patients [aged 5–18 years (32 hip joints)] with congenital and acquired femoral bone deformation. The efficiency of the proposed method was assessed in comparison with uniplanar planning using roentgenograms.</p><p><strong>Conclusions.</strong> Computerized operation planning using three-dimensional modeling improves treatment results by minimizing the likelihood of human errors and increasing planning and surgical intervention <br /> accuracy.</p>childrenhip joint3D-modelingcorrective hip osteotomyдетитазобедренный сустав3D-моделированиекорригирующая остеотомия бедра[Соколовский А.М., Соколовский О.А., Гольдман Р.К., Деменцов А.Б.
