Abstract

PURPOSE

To develop and assess three-dimensional models of physeal fractures in dog femurs (3D MPFDF) using radiographic imaging.

METHODS

The study was conducted in three phases: development of 3D MPFDF; radiographic examination of the 3D MPFDF; and comparative analysis of the anatomical and radiographic features of the 3D MPFDF.

RESULTS

The base model and the 3D MPFDF achieved high fidelity in replicating the bone structures, accurately maintaining the morphological characteristics and dimensions such as length, width, and thickness, closely resembling natural bone. The radiographs of the 3D MPFDF displayed distinct radiopaque and radiolucent areas, enabling clear visualization of the various anatomical structures of the femur. However, in these radiographs, it was challenging to distinguish between the cortical and medullary regions due to the use of 99% internal padding in the printing process. Despite this limitation, the radiographs successfully demonstrated the representation of the Salter-Harris classification.

CONCLUSIONS

This paper presents a pioneering project focused on technological advancement aimed at developing a method for the rapid and cost-effective production of three-printed models and radiographs of physeal fractures in dogs.

摘要

目的

使用放射影像学开发和评估犬股骨骺板骨折的三维模型（3D MPFDF）。

方法

该研究分三个阶段进行：3D MPFDF 的开发；3D MPFDF 的放射检查；以及 3D MPFDF 的解剖学和放射学特征的比较分析。

结果

基础模型和 3D MPFDF 在复制骨结构方面具有很高的保真度，准确地保持了长度、宽度和厚度等形态特征和尺寸，与天然骨非常相似。3D MPFDF 的射线照片显示出明显的不透射线和透明区域，能够清晰地显示股骨的各种解剖结构。然而，由于在打印过程中使用了 99%的内部填充材料，因此在这些射线照片中，皮质和髓质区域之间的区分具有一定难度。尽管存在这一限制，但射线照片成功地展示了 Salter-Harris 分类的代表性。

结论

本文介绍了一个专注于技术进步的开创性项目，旨在开发一种快速且具有成本效益的方法，用于生产犬骺板骨折的三维打印模型和射线照片。
