“…Наибольшее количество имплантированных винтов в кадавер-эксперименте было представлено Ma et al [14] на 20 препаратах грудного отдела с использованием билатеральных направителей, опорная площадка которых включала часть дужек, межпозвонковых суставов и остистый отросток. В группе free hand 156 (65 %) винтов были полностью окружены костью.…”

“…Результаты исследования демонстрируют высокую степень безопасности и точности имплантации при использовании навигационных направителей, что в целом соответ-ствует ранее опубликованным работам [10][11][12][13][14][15][16][17]. Стоит отметить, что в некоторых исследованиях продемонстрировано успешное использование матриц для установки винтов в С 1 [6], тогда как мы отметили недостаточную стабильность матрицы на данном уровне за счет малой площади поверхности.…”

“…More recently, Lu et al designed a template with 2 guide channels by reverse engineering for screw insertion of the lumbar [27], cervical [16], and thoracic [28] vertebrae. This template design with 2 channels has been popularized for insertion of spinal screws [11,12,29–32]. Compared with intraoperative 3D navigation methods, guide templates eliminate the need for complex equipment and complicated intraoperative procedures, thereby reducing the surgical duration.…”

BackgroundAtlantoaxial posterior pedicle screw fixation has been widely used for treatment of atlantoaxial instability (AAI). However, precise and safe insertion of atlantoaxial pedicle screws remains challenging. This study presents a modified drill guide template based on a previous template for atlantoaxial pedicle screw placement.Material/MethodsOur study included 54 patients (34 males and 20 females) with AAI. All the patients underwent posterior atlantoaxial pedicle screw fixation: 25 patients underwent surgery with the use of a modified drill guide template (template group) and 29 patients underwent surgery via the conventional method (conventional group). In the template group, a modified drill guide template was designed for each patient. The modified drill guide template and intraoperative fluoroscopy were used for surgery in the template group, while only intraoperative fluoroscopy was used in the conventional group.ResultsOf the 54 patients, 52 (96.3%) completed the follow-up for more than 12 months. The template group had significantly lower intraoperative fluoroscopy frequency (p<0.001) and higher accuracy of screw insertion (p=0.045) than the conventional group. There were no significant differences in surgical duration, intraoperative blood loss, or improvement of neurological function between the 2 groups (p>0.05).ConclusionsBased on the results of this study, it is feasible to use the modified drill guide template for atlantoaxial pedicle screw placement. Using the template can significantly lower the screw malposition rate and the frequency of intraoperative fluoroscopy.

“…The three dimensional (3D) printed guiding templates have been used for the placement screws of lumbar pedicle, C2 laminar, cervical pedicle, and thoracic pedicle. (10)(11)(12)(13) Recently, 3D-printed guiding templates have been developed to facilitate precise resection and accurate reconstruction of malignant bone tumors. (14,15) Even in a pilot study, 3D-printed calcaneal prosthesis has been applied in reconstruction after total calcanectomy.…”

3D-printed moulds facilitate making an anatomically matched cement spacer for reconstruction long bone defection after resection of tumors of humerous

Background: A nail and cement spacer is one of the option for the reconstruction of the proximal humerus after tumor resection among prosthesis unaffordable patients. However, making the cement spacer anatomically match its replacement remains challenging. Presentation of case: A 12-year-old boy was diagnosed with osteosarcoma in the right proximal humerus by core needle biopsy. After preoperative neo-adjuvant chemotherapy, a wide resection was performed, and the defect was reconstructed with an anatomically matched cement spacer. The cement spacer was fabricated using 3D-printed moulds, which were made according to the mirror image of the left humerus based on CT data. The post-operative course was uneventful, and at the 12-month follow-up, the patient is able to move with only some restriction in abduction and upward lift. The MSTD score was 21. Conclusion: Fabrication of an anatomically matched cement spacer using 3D-printed moulds is a simple, inexpensive, and reproducible procedure for reconstruction complex bone defect.
