BACKGROUND : 3D printing technology in hospitals facilitates production models such as point-of-care manufacturing . Orthopedic Surgery and Traumatology is the specialty that can most benefit from the advantages of these tools . The purpose of this study is to present the results of the integration of 3D printing technology in a Department of Orthopedic Surgery and Traumatology and to identify the productive model of the point-of-care manufacturing as a paradigm of personalized medicine .
METHODS: Observational, descriptive, retrospective and monocentric study of a total of 623 additive manufacturing processes carried out in a Department of Orthopedic Surgery and Traumatology from November 2015 to March 2020 . Variables such as product type, utility, time or materials for manufacture were analyzed .
RESULTS: The areas of expertise that have performed more processes are Traumatology, Reconstructive and Orthopedic Oncology . Pre-operative planning is their primary use . Working and 3D printing hours, as well as the amount of 3D printing material used, vary according to the type of product or material delivered to perform the process . The most commonly used 3D printing material for manufacturing is polylactic acid, although biocompatible resin has been used to produce surgical guides . In addition, the hospital has worked on the co-design of customized implants with manufacturing companies .
CONCLUSIONS: The integration of 3D printing in a Department of Orthopedic Surgery and Traumatology allows identifying the conceptual evolution from``Do-It-Yourself"to``POC manufacturing".
