We describe a technique that creates a 3-dimensional (3D) printed model from a patient's own computed tomography scan. This introduces an adjunct to conventional imaging for the surgical management of femoral acetabular impingement. The creation of a tactile 1:1 scale model with patient-specific anatomy allows for free manipulation and inspection. This is compared to planar imaging and 3D-reconstructed computer tomography scans, which are limited in their degrees of movement. With a minimal learning curve because of a highly iterative process, no prior experience in 3D printing is required to successfully complete this technique. The primary barrier of entry is the initial start-up cost of a 3D printer; however, the price per print is minimal. These models are valuable clinical tools that can be used in preoperative planning, patient education, and medical trainee learning.
我们描述了一种从患者自身的计算机断层扫描创建三维（3D）打印模型的技术。这为股骨髋臼撞击症的手术管理引入了一种传统成像的辅助手段。创建具有患者特定解剖结构的实体1:1比例模型可实现自由操作和检查。这与平面成像和3D重建计算机断层扫描相比，后者在运动程度上受到限制。由于该过程具有高度迭代性，学习曲线极小，成功完成这项技术无需3D打印方面的先验经验。进入该领域的主要障碍是3D打印机的初始启动成本；然而，每次打印的成本很低。这些模型是有价值的临床工具，可用于术前规划、患者教育和医学实习生学习。
