“…Одним из важных моментов, повлиявших на показатели коррекции деформации, стало использование металлоконструкций с транспедикулярными опорными элементами. Проведение транспедикулярных винтов под контролем навигационного оборудования, нейрофизиологического мониторинга позволило улучшить результаты в отношении правильной и точной установки опорных элементов спинальной системы в тела позвонков на протяжении дуги искривления [13,14]. Применение в ходе хирургического вмешательства при различных типах идиопатического сколиоза технологии, заключающейся в корректном и последовательном приложении корригирующих усилий, обеспечило значительную величину коррекции основной дуги деформации.…”

Background. Significant results have been achieved through the use of hybrid and transpedicular metal structures. However, when spinal systems are implanted during surgery in patients with severe forms and idiopathic scoliosis, a number of limitations arise. Not only the performance of corrective maneuvers during the operation but also the creation of mobility on the top of the main arc accompany the strategies of surgical treatment. Traditionally, mobilizing discectomy at the top of the spark is performed in patients with idiopathic scoliosis. Pedicle subtractional vertebrotomy and Ponte and Smith-Petersen osteotomy are most common in neuromuscular scoliosis and spinal deformity, with a predominance of the kyphotic component. Problems with correction of extremely low and neglected forms and idiopathic scoliosis in children remain. Aim. The present study aimed to provide a comparative analysis between using transpedicular spinal systems alone and in combination with a wedge osteotomy of the apical vertebra to correct spinal deformity in children with extremely severe right-sided idiopathic thoracic scoliosis. Materials and methods. The surgical treatment results of 20 children 15 to 17 years old with extremely severe forms of right-sided idiopathic thoracic kyphoscoliosis were included in the analysis. All patients underwent standard preoperative examination, including radiology, computed tomography, magnetic resonance imaging, and neurophysiological studies. The patients were divided into two groups according to the method used during the second stage of surgical treatment correction of deformity with the transpedicular system (1) alone or (2) in combination with a wedge osteotomy of the apical vertebra. Results. Patients from the first group showed an amount of scoliotic and kyphotic component correction ranging from 25% to 62% and from 21% to 56%, respectively. In patients from the second group, who underwent additional wedge osteotomy of the apical vertebrae during the operation, correction of the scoliotic and kyphotic components ranged from 36% to 74% and from 50% to 70%, respectively. Conclusion. In children with idiopathic thoracic kyphoscoliosis, performing a wedge corpectomy of the apical vertebral body is an effective additional mobilizing component, which allows achieving significant correction of both scoliotic and kyphotic curve components, restoring the physiological profile of the spine and body balance during the surgical intervention, and maintaining the achieved result during the long-term observation period.

“…In comparison to adults, however, the morphology of the spinal pedicle is different in children, and can vary based on age and within different segments 12. The use of 3D reconstruction models for pedicle screw placement in children is therefore warranted.…”

Background:Pedicle screw technique is commonly used treatment of adult spinal trauma, tumor, degeneration. The application of pedicle screws is very challenging in children because children have a fast growing spine and spinal pedicle morphology of children and adult has large difference. 3 D reconstruction individual navigation templates improve the success rate of pediatric pedicle screw system. This study is aimed to provide a precise method for lumbar spine pedicle screw placement in children using computer-aided design and rapid prototyping technology.Materials and Methods:Computed tomography (CT) scans of cadaver specimens of 4 children were obtained, and the raw data were reconstructed using three-dimensional reconstruction software. Pedicle screws were placed using the conventional method or by using individually designed navigation templates based on the principles of reverse engineering and rapid prototyping technology.Results:We evaluated the accuracy of the pedicle screws placed using the two methods by CT scan. Ten navigation templates were designed for placement of 20 lumbar pedicle screws in the navigation group, and CT scan confirmed that all the screws were placed accurately in the corresponding pedicle. Conversely, of the 20 lumbar pedicle screws placed using the conventional method, 3 screws perforated the pedicle. The findings showed that lumbar pedicle screw placement was successful using navigation templates in children.Conclusions:This technique is simple, easy to master, and allows personalized screw placement, thus providing a new and feasible method for lumbar pedicle screw placement in children.

The objective of this paper is to present an algorithm that allows us to record the movements and metrics that the surgeon does for placement of intrapedicular screw in lumbar region, and also provides de visual feedback that simulates the fluoroscope imagery. This algorithm is intended for be used with a model of the lumbar area in order to develop a simulator of a minimum invasive surgery, that will allows the resident training in this procedure.
