THREE-DIMENSIONAL PRINTING IN ORTHOPEDICS: WHERE WE STAND AND WHERE WE ARE HEADING

ABSTRACT Three-dimensional printing is a technology in expansion in the medical field. It also presents many applications in orthopedics. Our review article aims to describe 3D printing, types of 3D printers, and its use in the orthopedic field. 3D models can be created using tomography scans. Those models can then be manipulated, even simulating surgeries. It is possible to print biomodels, which will help us understand deformities and plan surgeries. Orthopedic surgeons must be updated in these disruptive technologies that may help their daily practice. Level of Evidence V, Expert opinion.

摘要 三维打印（3D printing）是当前在医疗领域蓬勃发展的技术，在骨科领域亦具备多种应用场景。本综述旨在阐述三维打印技术、三维打印机的分类，以及该技术在骨科领域的应用。可通过断层扫描影像构建三维模型，此类模型可进行编辑调整，甚至可用于模拟手术流程。此外还可打印生物模型（biomodels），此类模型有助于术者与研究者理解机体畸形结构并制定手术方案。骨科医师需及时掌握此类颠覆性技术，以助力其日常临床工作。证据等级：V级，专家意见。
