Resumo: | Introduction: The proximal humeral fractures are becoming more frequent, with a greater tendency for its surgical treatment by osteosynthesis with plate and locked screws. The mechanical and biological failure in these fractures and devices, despite the evolution of this type of implants, highlighted the synthetic bone grafts became an option.Material and Methods: Over a period of 96 months, patients considered were those with proximal humeral fractures treated surgically with a plate and locked screws, and in which β-tricalcium phosphate bone graft had been used. Functional results were evaluated by the shoulder range of motion as the radiological results.Results: In 19 patients, with a medial follow up of 53 months, we obtained an average shoulder range of motion of 140º in abduction, 142º in forward flexion, 37º in external rotation and L3 hand position in internal rotation for a cefalo-diaphyseal angle of 136º.Discussion: The β-tricalcium phosphate synthetic bone graft allows the maintenance of reduction after fixation of proximal humeral fractures stabilized with plate and locked screws. This reduction which means the maintenance of cefalo-diaphyseal angle is in close relationship with functional results as shown by shoulder range of motion in all planes.Conclusion: The β-tricalcium phosphate synthetic bone graft should be seen as an adjuvant therapy in extramedullary fixation of proximal humeral fractures, especially those with greater comminution of the medial calcar. |

Pela falência mecânica e biológica, apesar da evolução deste tipo de implantes, a utilização de enxertos ósseos sintéticos passaram a ser uma opção.Material e Métodos: Num período de 96 meses, avaliámos os doentes com fraturas proximais do úmero, tratados cirurgicamente com placa e parafusos bloqueados e nos quais foi usado enxerto ósseo sintético de fosfato β-tricálcico. Avaliaram-se os resultados funcionais pelo arco de mobilidade e pelos exames radiográficos.Resultados: Nos 19 doentes avaliados, para um follow-up médio de 53 meses, obteve-se um arco de mobilidade com valores médio de abdução de 140º, flexão anterior de 142º, rotação externa de 37º e rotação interna com mão a L3, para um ângulo cefalo-diafisário de 136º.Discussão: A utilização de enxerto ósseo sintético de fosfato β-tricálcico permite a estabilização da redução após fixação das fraturas proximais do úmero estabilizadas com placa e parafusos bloqueados. Esta redução que se traduz na manutenção do ângulo cefalodiafisário, permite a obtenção de bons resultados funcionais como o demonstra o arco de mobilidade nos vários planos.Conclusão: O enxerto ósseo sintético de fosfato β-tricálcico deverá ser encarado como uma terapêutica auxiliar na osteossíntese extramedular das fraturas proximais do úmero, principalmente naquelas com maior dificuldade de manutenção da redução pela maior cominução do calcar medial.Ordem dos Médicos2016-01-29info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfapplication/pdfimage/jpegimage/jpegimage/jpegapplication/mswordapplication/mswordapplication/mswordapplication/pdfimage/tiffimage/tiffimage/jpeghttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233oai:ojs.www.actamedicaportuguesa.com:article/6233Acta Médica Portuguesa; Vol. 29 No. 1 (2016): January; 41-45Acta Médica Portuguesa; Vol. 29 N.º 1 (2016): Janeiro; 41-451646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporenghttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/4581https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/4743https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/7499https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/7500https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/7501https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/7653https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/7654https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/7655https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/7910https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/8102https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/8103https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6233/8104Direitos de Autor (c) 2016 Copyright © Ordem dos Médicos 2016info:eu-repo/semantics/openAccessSarmento, MarcoMartins, SamuelMonteiro, Jacinto2022-12-20T11:04:46Zoai:ojs.www.actamedicaportuguesa.com:article/6233Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:19:16.745678Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
