Resumo: Objective: To identify the parallax effect on radiographs of upper and lower limbs in everyday orthopedics. Methods: This was an experimental, descriptive-theoretical study, with data analysis of digital radiographs from a tertiary trauma hospital in southern Brazil. Results: The parallax effect and magnification recorded different degrees of deformation, in the analysis of radiographs of the upper limbs, the AP radiograph of the shoulder showed greater degrees of distortion at a predetermined point (4.00%), in lower limbs the pelvis showed a greater degree of magnification (7.85%). Conclusions: There was a positive association between image magnification and the size of the film or structure to be analyzed. The parallax effect has a significant impact on image distortion in the context of orthopedic trauma. Level of Evidence III.

Métodos: Este foi um estudo experimental, descritivo-teórico, com análise de dados de radiografias digitais de um hospital de trauma terciário sul-brasileiro. Resultados: O efeito paralaxe e magnificação registrou diferentes graus de deformação, em análise de radiografias de membros superiores a radiografia em AP do ombro apresentou maior graus de distorção em um ponto pré-determinado (4,00%), em membros inferiores a pelve apresentou maior grau de magnificação (7,85%). Conclusões: Houve uma associação positiva entre a magnificação de imagem e o tamanho do filme ou estrutura a ser analisada. O efeito paralaxe tem impacto significativo sobre a distorção de imagens no contexto de trauma ortopédico. Nível de evidência III. Estudo diagnóstico – investigação de um exame para diagnóstico, - estudo com pacientes não consecutivos, sem padrão de referência ouro.SciELO PreprintsSciELO PreprintsSciELO Preprints2024-02-27info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/812010.1590/SciELOPreprints.8120enghttps://preprints.scielo.org/index.php/scielo/article/view/8120/projetoCopyright (c) 2024 Bruno Dada Gulini, Fernando Ferraz Faria, Jamil Faissal Sonihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGulini, Bruno DadaFaria, Fernando FerrazSoni, Jamil Faissalreponame:SciELO Preprintsinstname:Scientific Electronic Library Online (SCIELO)instacron:SCI2024-02-20T02:31:21Zoai:ops.preprints.scielo.org:preprint/8120Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2024-02-20T02:31:21SciELO Preprints - Scientific Electronic Library Online (SCIELO)false
