Background: The agreement for the treatment of proximal humerus fractures is low. Interpretation of exams used for diagnosis can be directly associated with this limitation. This study proposes to compare the agreement between experts and residents in orthopedics for treatment indication of proximal humerus fractures, utilizing 3Dmodels, holography (augmented reality), x-rays, and tomography as diagnostic methods. Methods: Twenty orthopedists (ten experts in shoulder and elbow surgery and ten experts in traumatology) and thirty resident physicians in orthopedics evaluated nine fractures of the proximal humerus, randomly distributed as x-rays, tomography, 3D-models and holography, using the Neer and AO / OTA Classifications. After, we evaluated the interobserver agreement between treatment options (conservative, osteosynthesis and arthroplasty) and whether the experience of the evaluators interfered with the results. Results: The interobserver agreement analysis showed the following kappa-values: κ = 0.362 and κ = 0.306 for experts and residents (3D-models); κ = 0.240 and κ = 0.221 (X-ray); κ = 0.233 and κ = 0.123 (Tomography) and κ = 0.321 and κ = 0.160 (Holography), for experts and residents respectively. Moreover, residents and specialists were discordant in the treatment indication using Tomography as a diagnostic method (p = 0.003). The same was not seen for the other diagnostic methods (p > 0.05). Conclusions: Three-dimensional models showed, overall, the highest interobserver agreement (experts versus residents in orthopedics) for the choice of treatment of proximal humerus fractures compared to X-ray, Tomography, and Holography. Agreement in the choice of treatment among experts that used Tomography and Holography as diagnostic methods were two times higher compared to residents.

“…A precisão das impressoras 3D pode variar devido a diferentes fatores, sendo altamente dependente do tipo e condicionamento do material disponível para confecção dos biomodelos e disponibilidade e calibragem do equipamento (Ibrahim et al, 2009;Kim et al, 2018;Stansbury & Idacavage, 2016). (Arvier et al, 1994;Assis et al, 2010;D'Urso et al, 1998;Ganry et al, 2018;Ibrahim et al, 2009;Mehrotra & Markus, 2021;Meurer et al, 2003;Mothes et al, 2018;Silva et al, 2008;Stansbury & Idacavage, 2016;Steenberghe et al, 2002;Zeller et al, 2021). Por serem praticamente idênticos às estruturas reais, aumentam a previsibilidade cirúrgica, reduzindo o tempo do procedimento e consequentemente diminuem custo e morbidade (Meurer et al, 2003;Mothes et al, 2018;Zeller et al, 2021).…”

A utilização de sistemas computacionais permite a educação continuada aos profissionais, o estudo e planejamento cirúrgico virtual e a obtenção de objetos físicos diretamente a partir dos dados gerados. As imagens obtidas a partir da tomografia computadorizada podem ser manipuladas através de softwares livres. A prototipagem rápida é amplamente utilizada em Cirurgia e Traumatologia Buco-maxilo-faciais permitindo aumentar a previsibilidade cirúrgica, reduzindo o tempo associado ao procedimento e consequentemente resultando em menor morbidade ao paciente, baixando os custos vinculados à assistência em saúde. Este trabalho descreve o protocolo do emprego de técnicas de prototipagem rápida aplicadas a pacientes com necessidades de tratamento na especialidade de Cirurgia e Traumatologia Buco-maxilo-faciais, em nível terciário de atenção em saúde, vinculados ao Sistema Único de Saúde, em um hospital escola do sul do Brasil. Explora ainda, parâmetros relacionados a aquisição da imagem por tomografia computadorizada, características estruturais dos softwares utilizados, dos equipamentos e critérios de qualidade dimensional dos materiais utilizados. A adoção dessas tecnologias poderá trazer melhora na qualidade assistencial, devendo ser estimulada dentro do Sistema Único de Saúde.

Background Three‐dimensional (3D) printing has seen increasing interest in surgery, where it improves the visualization of difficult anatomy in complex cases. This literature review investigates the benefits and limitations of 3D printed models in preoperative planning in the field of orthopaedic surgery. Methods A literature search was performed using the Ovid platform on the Embase and MEDLINE databases using the terms ‘3D printing’, ‘Orthopaedics’ and ‘Surgical Planning’. Studies using 3D printed models as a part of preoperative planning were included. All others were excluded. Data regarding the metrics used to assess the benefit of the use of 3D models, surgical outcome, and surgeon or patient opinion on the technology were extracted. Results A total of 41 studies resulted. Eight (19.5%) were case–control studies, the remainder were case reports or case series. Assessment of benefit was mostly subjective, although the case–control studies included objective metrics such as operation time, intraoperative blood loss and intraoperative fluoroscopy time. The use of 3D printing technology showed subjective benefit for both patient and surgeon as well as indicating clinically significant improvements in intraoperative metrics. Conclusion Despite the current absence of large scale trials, 3D printing has clear benefits in preoperative planning, particularly when utilized in complex cases. A streamlined workflow for case selection, in‐house model creation and preoperative rehearsals is still required to be developed before the process is ready for routine use. Evidence supports an improvement in intraoperative metrics and patient engagement but data to support improved clinical outcome is lacking.
