Abstract

To evaluate a proposed three-dimensional (3D) printing process of a biomodel developed with the aid of fused deposition modeling (FDM) technology based on computed tomography (CT) scans of an individual with nonunion of a coronal femoral condyle fracture (Hoffa's fracture).  Thus, we used CT scans, which enable the evaluation of the 3D volumetric reconstruction of the anatomical model, as well as of the architecture and bone geometry of sites with complex anatomy, such as the joints. In addition, it enables the development of the virtual surgical planning (VSP) in a computer-aided design (CAD) software. This technology makes it possible to print full-scale anatomical models that can be used in surgical simulations for training and in the choice of the best placement of the implant according to the VSP. In the radiographic evaluation of the osteosynthesis of the Hoffa's fracture nonunion, we assessed the position of the implant in the 3D-printed anatomical model and in the patient's knee.  The 3D-printed anatomical model showed geometric and morphological characteristics similar to those of the actual bone. The position of the implants in relation to the nonunion line and anatomical landmarks showed great accuracy in the comparison of the patient's knee with the 3D-printed anatomical model.  The use of the virtual anatomical model and the 3D-printed anatomical model with the additive manufacturing (AM) technology proved to be effective and useful in planning and performing the surgical treatment of Hoffa's fracture nonunion. Thus, it showed great accuracy in the reproducibility of the virtual surgical planning and the 3D-printed anatomical model.

摘要

为评估一种基于股骨髁冠状面骨折（霍法骨折）不愈合个体的计算机断层扫描（CT）扫描结果，借助熔融沉积建模（FDM）技术开发生物模型的三维（3D）打印工艺。因此，我们使用了CT扫描，它能够评估解剖模型的3D体积重建，以及关节等解剖结构复杂部位的结构和骨骼几何形状。此外，它还能在计算机辅助设计（CAD）软件中进行虚拟手术规划（VSP）。这项技术使打印全尺寸解剖模型成为可能，这些模型可用于手术模拟训练，并根据VSP选择植入物的最佳放置位置。在霍法骨折不愈合的骨固定影像学评估中，我们评估了植入物在3D打印解剖模型和患者膝关节中的位置。3D打印的解剖模型显示出与实际骨骼相似的几何和形态特征。在将患者膝关节与3D打印解剖模型进行比较时，植入物相对于不愈合线和解剖标志的位置显示出很高的准确性。事实证明，使用虚拟解剖模型和3D打印解剖模型以及增材制造（AM）技术在规划和实施霍法骨折不愈合的手术治疗方面是有效且有用的。因此，它在虚拟手术规划和3D打印解剖模型的再现性方面显示出很高的准确性。
