et al.

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 technologie… Show more

Resumo Objetivo O interesse em utilizar a impressão 3D na área da saúde tem crescido ao longo dos anos, dadas as suas vantagens e o seu potencial na rápida fabricação de dispositivos e implantes personalizados com geometrias complexas. Assim, o objetivo do presente estudo foi comparar o comportamento de fixação mecânica de um parafuso de interferência impresso em 3D, produzido pela modelagem fundida de deposição do filamento de ácido polilático (PLA), com o de um parafuso de interferência de titânio. Métodos Oito tendões suínos flexores profundos, de aproximadamente 8 mm de largura e 9 cm de comprimento, foram utilizados como enxerto e fixados em um bloco de poliuretano de 40 PCF em cada uma de suas extremidades. Um grupo foi fixado apenas com parafusos de interferência de titânio (grupo 1) e o outro apenas com parafusos PLA impressos em 3D (BR 20 2021 018283-6 U2) (grupo 2). Os testes foram realizados utilizando uma máquina de teste universal eletromecânica EMIC DL 10.000 no modo de tração axial. Resultados O grupo 1 (titânio) obteve força máxima de 200 ± 7 N com deformação média do enxerto de 8 ± 2 mm, e a força máxima do grupo 2 (PLA) foi de 300 ± 30 N e deformação média do enxerto de 7 ± 3 mm. Ambos os parafusos de titânio e PLA forneceram boa fixação de enxerto no bloco de poliuretano, sem deslizamento ou deformação aparente. Em todas as amostras o teste culminou na ruptura do enxerto, com cerca de 20 mm de deformação em relação ao comprimento inicial. Conclusão O parafuso PLA impresso em 3D proporcionou boa fixação, semelhante à de sua contraparte de titânio, produzindo resultados satisfatórios e promissores.

The rapid development of science and technology, especially those related to computing and data processing, creates more and more directions for the development of surgical techniques and imaging methods in modern medical practice. Since the beginning of the first decade of the 2000s, surgical practitioners have increasingly begun to use the capabilities of digital technologies in order to most effectively carry out invasive interventions. The purpose of the research: based on an analysis of modern literature, to assess the current state of development of IT technologies in surgical treatment of fractures. Materials and methods: a search was conducted in open electronic scientific databases PubMed and Russian scientific electronic library eLibrary using keywords and phrases: fractures, digital technologies, surgical treatment. Results: based on the results of numerous both domestic and foreign publications, it can be concluded that IT technologies are actively being introduced into the clinical practice of trauma specialists and have great potential for the surgical treatment of fractures of various types. Conclusion: The use of computing technologies to develop algorithms for patient management, computer modeling of surgical intervention, and 3D printing can improve the surgical treatment of fractures, make treatment more individual and patient-oriented, which has led to the rapid development of this area of development in recent decades. Evaluation and analysis of data is the future and a step in all medical science and practice. Information technologies will in the near future provide a breakthrough and a radically new level of healthcare development.
