We designed a patient-specific, human-like, reliable, and cost-effective prototype of the examined pathological spine through open-source editing software analysis, a desktop 3D printer, and alginate material. We aimed to validate that the major surgical steps and anatomy replicated the real surgery as it would be conducted in actual patients.We cover the fundamental principles and procedures involved in 3D printing, from spine imaging to phantom manufacturing. Three representative simulation cases were included in the study. All phantoms were sequentially evaluated by surgeons for fidelity. Following each surgery, participants were given a survey that included 20 questions regarding the fidelity of the training phantom.We validated this simulation model by analyzing neurosurgeons' performance on the phantom trainer. Based on a 20-item survey to test content validity and reliability, there was little variation among participants' ratings, and the feedback was consistently positive. The gross appearance of the phantom was analogous to the cadaveric specimen and the phantoms demonstrated an excellent ability to imitate the intraoperative condition. The plastic material expenditure ranged from 170 to 470 g, and the alginate expenditure was 450 g. The total cost of acrylonitrile butadiene styrene (ABS) varied from $5.1 to $17.6 ($0.03 per gram of ABS), whereas the total cost of alginate was $14.3. The average cost of our phantoms was approximately $25.7, and the 3D printer used in this study costs approximately $200.The basic properties of this phantom were similar to cadaveric tissue during manipulation. We believe our phantoms have the potential to improve skills and minimize risk for patients when integrated into trainee education.</p>","PeriodicalId":16544,"journal":{"name":"Journal of neurological surgery.

Herein, we aimed to compare the results of treatment of different vertebral levels following early or late kyphoplasty.Between 2017 and 2022, 283 patients with single-level osteoporotic vertebral fractures were retrospectively reviewed. Patients in whom visual analog scale (VAS) values were recorded, and osteoporosis tests performed were included in the study. Traumatic single-level fractures in patients with osteoporosis who were aged > 60 years were included. Patients with a history of malignancy, previous spinal surgery, or neurological deficits were excluded. A total of 100 patients met the inclusion criteria. A total of 50 patients underwent kyphoplasty within 3 days of sustaining the fracture (Group 1), and 50 patients underwent kyphoplasty more than 3 days after sustaining the fracture (Group 2). Groups A, B, and C included fractures at the T7-T11 levels, T12-L1 levels (thoracolumbar junction), and L2-L5 levels, respectively. These groups were compared among themselves. Bilateral balloon kyphoplasty was performed under sedation in the prone position. Preoperative and postoperative VAS scores, anterior vertebral heights, and kyphotic angles (KAs) were measured and recorded. The vertebral segments that underwent early and late kyphoplasty were also compared among themselves.In all the patients who underwent early or late kyphoplasty, there was a significant decrease in the KA and a significant increase in vertebral heights during the early postoperative period (<i>p</i> < 0.001). There was no significant change in the vertebral heights and KA between the early and late postoperative periods (<i>p</i> = 0.780). Early kyphoplasty demonstrated better pain control with a greater improvement in VAS score (<i>p</i> < 0.001) than late kyphoplasty.Kyphoplasty plays an important role in reducing pain and ensuring early mobilization in older patients.
