Preoperative CT scans were used to create 3D printed models for surgical planning and simulation. Intraoperative CT was employed post-needle insertion and pre-cement injection for accuracy verification. Outcomes were measured using the visual analog scale (VAS) for pain, Oswestry disability index (ODI) for functionality, and assessments of vertebral height and kyphotic angle. Complications recorded included cement leakage, nerve injury, and adjacent vertebral fracture. Subgroup analysis was performed to compare outcomes between thoracolumbar and lumbar fractures.Results: Average operation time was 35.6 ± 8.4 minutes, and fluoroscopy time was 12.3 ± 3.7 seconds. Intraoperative CT confirmed precise needle placement, with no occurrences of cement leakage or nerve injury. VAS scores improved from 8.2 ± 1.5 preoperatively to 2.1 ± 0.9 postoperatively, and ODI scores from 72.3 ± 9.8% to 18.4 ± 6.7%. Subgroup analysis showed no significant differences in clinical or radiographic outcomes between thoracolumbar and lumbar groups, although a higher cement volume was used in lumbar vertebrae (3.6 vs 2.8 mL, p< 0.001). There was significant post-surgical restoration and maintenance of vertebral height and kyphotic angle, with no adjacent vertebral fractures reported.Conclusion: PVP using 3D printing and intraoperative CT for thoracolumbar osteoporotic vertebral fractures is safe, accurate, and effective in pain relief, functional improvement, and vertebral morphology restoration. The 3D models enhance surgical planning, while intraoperative CT provides real-time feedback for needle and cement placement.Keywords: percutaneous vertebroplasty, 3D printing, intraoperative CT guidance, osteoporotic vertebral fractures
