One of the more recent fracture-healing methods comprises applying patient-specific 3D printing. An optimal fracture-healing method would accurately print and embed a customized implant at the defect site of the fracture. In this study, to provide a standardized 3D printing process, the entire process of making a fracture model, manufacturing the customized 3D printing, and implanting the result was conducted through animal experiments. A fracture treatment 3D printing process was established and a fracture model was produced. X-ray and micro-computed tomography (CT) images were acquired and the portions with the fractured bones were extracted by segmentation and reconstruction using image preprocessing software. Based on this, 3D modeling of the fracture site scaffold was performed, and the 3D printing protocol was experimentally verified through polylactic acid (PLA)-based 3D printing and implantation at the fracture site. The entire process of making the fracture model, manufacturing the customized 3D-printed bone fragment, and implanting it in the defect site was performed based on 3D printing. There is a need for further animal clinical validation and histological studies on the fracture recovery process according to 3D printing protocols. Nevertheless, this approach (performing the implantation process of a customizable 3D printing scaffold for replacing atypical fractures using X-ray and micro-CT images) is expected to play a new role in fracture treatment.
