To evaluate the effect of 3d printed models on surgical pre-operative planning of complex spinal deformities.
In our study, five orthopedic surgeons made surgical planning of 5 patients with severe spinal deformity in three conditions: X-ray with computer tomography (X-ray-CT), 3D-computed tomography (3dCT), and 3d printed spine models. Operation plans were examined according to the level and number of instrumentations, osteotomy level, and time required for decision-making.
X-ray-CT, 3dCT, and 3d modeling methods were compared, and no statistically significant difference was observed in the number of screws and osteotomy score to be used in operation. The time required for decision ranking is 3d Model, 3d CT, and Xray-CT.
3d printed models do not influence the operative plan significantly; however, it reduces surgical planning time at pre-op duration, and those models gave some opportunities to practice with implants on a patient's 3d spine model. .
评估3D打印模型对复杂脊柱畸形手术术前规划的影响。
在我们的研究中，五位骨科医生在三种情况下对5例严重脊柱畸形患者进行手术规划：X线联合计算机断层扫描（X线-CT）、三维计算机断层扫描（3D-CT）和3D打印脊柱模型。根据内固定的节段和数量、截骨节段以及决策所需时间对手术方案进行评估。
对X线-CT、3D-CT和3D建模方法进行比较，手术中使用的螺钉数量和截骨评分无统计学显著差异。决策排序所需时间为3D模型、3D-CT和X线-CT。
3D打印模型对手术方案无显著影响；然而，它减少了术前手术规划时间，并且这些模型为在患者的3D脊柱模型上进行植入物操作提供了一些机会。
