3D列印在小兒骨科領域的應用

近年來「3D生物列印技術」在骨科領域帶來革命性的進展，並在世界各國引起廣大的注意。對於複雜人體的解剖結構，可以迅速在幾天內獲得患者手術部位最真實清晰的模型。透過這樣的技術，讓外科醫師能夠在手術前精確地規劃手術，提高手術成功率，同時節省醫療費用。3D生物列印技術可應用的範圍包括：術前計畫，手術模擬，病患量身打造的專屬植入物或手術輔助工具，以及支架輔具等等。有了這樣高階的科技技術，可以實現按個人量身打造的精準醫療。這樣的醫療服務更是特別符合兒童病患治療的需求，因為兒童的體型會隨著成長產生很大的變異，透過3D生物列印技術可以按重組影像列印出適合的模型或專屬的植入物，可以讓治療更有效率更精確，給病患帶來滿意的臨床結果。本文主要透過回顧相關文獻，概述近年來「3D生物列印技術」的基礎原理以及目前在小兒骨科領域的相關進展與應用。

Three-dimensional (3D) printing technologies, also known as ＂additive manufacturing＂ and ＂rapid prototyping＂, are revolutionizing orthopaedic clinical practice nowadays, allowing anatomical structures of any complexity to be manufactured in just days. Such technologies can make surgery for complex cases more precise, more cost-effective, and possibly easier to perform. Preoperative parameter measurement and surgical planning, along with the application of a 3D-printed navigation template, can effectively reduce errors associated with inexperience and poor operative technique. Applications include preoperative planning, surgical simulation, patient-specific instrumentation and implants such as bio-printing, prosthetics, and orthotics. With these new techniques and technologies, we must ensure that precise and individualized treatments are possible. This is especially important for children, who show great individual physical differences. This article aims to review the basic principles of 3-dimensional technologies, including imaging, design, numerical simulation, and printing, and their current applications in pediatric orthopedic disorders.
