Conceptual Evolution

Abstract 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”.

Abstract INTRODUCTION 3D printing technology is penetrating the healthcare field at an astonishing rate. The reduction of its costs, makes it more accessible to everyone. MATERIAL AND METHODS 35-year-old woman who had functional limitation in her right hip due to pelvic ring fracture in her childhood. She had dysmetria of lower limbs and femoral anteversion of 40 degrees. Imaging tests showed vicious consolidation of the right hemipelvis associated with antero-medial displacement. RESULTS Preoperative, we performed her 3D printing pelvic ring model. Osteotomies were digital planned (iliac crest, superior pubic ramus, incomplete of inferior pubic ramus, and semicircular of posterior column) and also how many degrees we would need for rotation the osteotomized fragment. Posterior column osteotomy was the most difficult, so we designed 3D surgical printing cutting guide able to being inserted into the iliac fossa. We used it to introduced four Kirschnner wires that leads us as a guide to avoid the greater sciatic notch. O-arm navigation system helped us make sure to achieve more precision. 3D printing pelvic ring model was sterilized to pre-contouring osteosynthesis plates. After two years of follow-up, good functional results were observed, without gait claudication either limb dysmetria. Her range of motion is 105 degrees of hip flexion, 20 degrees of internal hip rotation and 40 degrees of external hip rotation. Complete radiological consolidation was observed. CONCLUSION Digital planning and 3D printing technology allows to improve three-dimensional compression of bone pathology leading to a higher likelihood of a predictable ideal outcome compared to conventional techniques.

Surgical Guides

Additive manufacturing or 3-dimensional (3D) printing technology has an incredulous ability to create complex constructs with high exactitude. Surgical guides printed using this technology allows the transfer of the virtual surgical plan to the operating table, optimizing aesthetic outcomes, and functional rehabilitation. A vast variety of materials are currently being used in medical 3D printing, including metals, ceramics, polymers, and composites. The guides fabricated with titanium have high strength, excellent biocompatibility, and are sterilizable but take time to print and are expensive. We have thus followed a hybrid approach to fabricate an inexpensive surgical guide using metal where the advantage of 3D printing technology has been combined with the routinely followed investment casting procedure to fabricate guides using nickel–chromium, which has all the advantages of a metal and is cost-effective.

Purpose The purpose of this paper is to present several insights on how disruptive technologies potentially impact the eco-performance of entire supply chains, by providing performance improvements compared to existing technologies, enabling more efficient manufacturing methods and affecting the entire structure of the supply chain. Design/methodology/approach To illustrate the authors’ position, a case from the construction sector is presented, for which the feasibility and impact of 3D printing technology has been studied. The empirical study focuses on the effect of the use of 3D printing technology on the building supply chain, aimed primarily at manufacturing companies in construction, but including suppliers, architects and designers as well. Findings 3D printing of concrete potentially provides several improvements in manufacturing performance, such as a shortening of lead times, integration of functions and allowing for reduced material usage, therefore possibly turning production steps within the construction supply chain obsolete while also reducing logistical and production efforts. Research limitations/implications Whether disruptive technologies other than 3D printing have a similar potential is unknown. Though the case study shows the potential of disruptive technologies in impacting supply chains, the authors realize that more empirical work is needed to understand the underlying mechanisms. Originality/value The originality of this paper lies in relating disruptive technological advancements to manufacturing technologies and transitions of supply chains’ eco-performance.

Oral Soft Tissue

Three-dimensional (3D) printing technology allows the production of an individualized 3D object based on a material of choice, a specific computer-aided design and precise manufacturing. Developments in digital technology, smart biomaterials and advanced cell culturing, combined with 3D printing, provide promising grounds for patient-tailored treatments. In dentistry, the “digital workflow” comprising intraoral scanning for data acquisition, object design and 3D printing, is already in use for manufacturing of surgical guides, dental models and reconstructions. 3D printing, however, remains un-investigated for oral mucosa/gingiva. This scoping literature review provides an overview of the 3D printing technology and its applications in regenerative medicine to then describe 3D printing in dentistry for the production of surgical guides, educational models and the biological reconstructions of periodontal tissues from laboratory to a clinical case. The biomaterials suitable for oral soft tissues printing are outlined. The current treatments and their limitations for oral soft tissue regeneration are presented, including “off the shelf” products and the blood concentrate (PRF). Finally, tissue engineered gingival equivalents are described as the basis for future 3D-printed oral soft tissue constructs. The existing knowledge exploring different approaches could be applied to produce patient-tailored 3D-printed oral soft tissue graft with an appropriate inner architecture and outer shape, leading to a functional as well as aesthetically satisfying outcome.

Abstract BackgroundPoint-of-care (POC) manufacturing and distributed production represent a paradigm shift in the health system that is becoming critical during the COVID-19 pandemic. University hospitals are also taking on the role of manufacturers of custom-made solutions thanks to 3D printing technology.Case DescriptionWe present a monocentric observational study regarding the distributed manufacture of three groups of products during the period of the COVID-19 pandemic from 14 March to 10 May 2020: personal protective equipment, ventilatory support, and diagnostic and consumable products.Discussion and EvaluationNetworking during this period has enabled the delivery of a total of 17.276 units of products manufactured using 3D printing technology. The most manufactured product was the face shields and ear savers, while the one that achieved the greatest clinical impact was the mechanical ventilation adapters and swabs. The products were manufactured by individuals in 57.3% of the cases, and our hospital acted as the main delivery node in a hub with 10 other hospitals. The main advantage of this production model is the fast response to stock needs, being able to adapt almost in real time.ConclusionsThe role of the manufacturing hospital allows the reconciliation of in-house and distributed manufacturing with traditional production, providing custom-made adaptation of the specifications, as well as maximum efficiency in the working and availability of resources, which is of special importance at critical times for health systems such as the current COVID-19 pandemic.
