Összefoglaló szövege

Introduction
3D printed models facilitate the understanding of complex anatomical relationships, aiding preoperative surgical planning. Their use is beneficial in patient education, but also in reducing the operative time according to the results of scientific publications from the last five years. In spine surgery, there is currently no consensus or recommendation on when 3D printed models should and should not be used.
Aim
We aimed to develop a questionnaire-based survey to investigate the usefulness of 3D printed models in complex spine surgery cases.
Method
CT scans of patients in 6 complex spine surgery cases were segmented using Mimics® software. Segmentation accuracy was quantified using Dice Similarity Index (DSI). The models were fabricated using fused deposition modeling (FDM) 3D printing technology. CT images of the models were taken, segmented and compared with the original virtual models to assess geometric accuracy. A questionnaire, consisting 6 questions for each of the cases (36 questions in total that can be answered by a scale from 1 to 10) was filled out by spine surgeons (n=41) from multiple hospitals after reviewing the imaging (RTG, MR, CT) scans and then examining the 3D printed models in hand. The digital form of the questionnaire was created using SurveyMonkey® platform. Statistical analysis of the data was performed using SPSS® 23.0, G*Power software.
Results
The geometric variation of the printed models was <1mm in every case. The responses show that spine surgeons find the models very useful (8.75±0.14, ɑ=0.05). Further analysis shows that there is significant difference between orthopedic and neurosurgeons (p<0.001), and between groups with different years of clinical practice (p<0.05). The additional benefit of 3D printed models seems to be the greatest in patient education (p<0.001).
Conclusion
For the clinical integration of 3D printed models, we need to know how surgeons perceive their usefulness. The role of basic skills is unknown in the acceptance of 3D printed physical models. The developed questionnaire survey could greatly contribute to the clinical integration of 3D printed models, providing evidence for different funding parties.
Funding
No funding was used.
