Planning for corrective osteotomy of the femoral bone using 3D-modeling. Part I

Introduction. In standard planning for corrective hip osteotomy, a surgical intervention scheme is created on a uniplanar paper medium on the basis of X-ray images. 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.Aims. To develop a new three-dimensional method for planning and performing corrective osteotomy of the femoral bone, using visualizing computer technologies.Materials and methods. 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.Conclusions. Computerized operation planning using three-dimensional modeling improves treatment results by minimizing the likelihood of human errors and increasing planning and surgical intervention accuracy.

Introduction. Three-dimensional (3D) modeling and prototyping are increasingly being used in various branches of surgery for planning and performing surgical interventions. In orthopedics, this technology was first used in 1990 for performing knee-joint surgery. This was followed by the development of protocols for creating and applying individual patterns for navigation in the surgical interventions for various bones. Aim. The study aimed to develop a new 3D method for planning and performing corrective osteotomy of the femoral bone using an individual pattern and to identify the advantages of the proposed method in comparison with the standard method of planning and performing surgical intervention. Materials and methods. A new method for planning and performing corrective osteotomy of the femoral bone in children with various pathologies of the hip joint is presented. The outcomes of planning and performing corrective osteotomy of the femoral bone in 27 patients aged 5 to 18 years (32 hip joints) with congenital and acquired deformity of the femoral bone were analyzed. Conclusion. The use of computer 3D modeling for planning and implementing corrective interventions on the femoral bone improves the treatment results owing to an almost perfect performance accuracy achieved by the minimization of possible human errors reduction in the surgery duration; and reduction in the radiation exposure for the patient.
