Resumo: The present study aimed the viability evaluation of solid intramedullary rods made with polyamide 12 and coated with hydroxyapatite in experimentally osteotomized humerus of young roosters (white Plymouth rock). Sixteen animals of 45 days old each were used. After general anesthesia, they underwent to complete transverse osteotomy of the right humerus diaphysis to implant the already described rods which filled the entire length of the medullary cavity and were fixed by two cortical stainless steel screws in each bone fragment. The surgical technique was well succeeded without any trans-operative intercurrence. Through clinical and radiographic examination, it was observed that soon after the anesthesia recovery, six rods (37,5%) broke next to the fracture focus and the same was noticed with the others (62,5%) on seventh day post-surgery. Based on the obtained results, it can be hypothesized that polyamide 12 rods resistance could have been affected by all the thermal stages necessary to its incorporation with hydroxyapatite. Furthermore, the roosters’ age may also have contributed to adverse outcomes. However, future researches will be necessary to confirm those hypotheses.

Se utilizaron 16 aves con 45 días de vida. Después de la anestesia general, se les realizó una osteotomía transversal completa de la diáfisis del húmero derecho para la implantación de dichas uñas que llenaban todo el canal espinal y se bloquearon con dos tornillos metálicos corticales en cada fragmento óseo. La técnica quirúrgica fue fácilmente factible, sin complicaciones intraoperatorias. A través de exámenes clínicos y radiográficos, se observó que poco después del retorno de la anestesia, seis uñas (37.5%) se rompieron cerca del foco de fractura ósea, notándose lo mismo en las otras (62.5%) al séptimo día de la cirugía. Con base en los datos obtenidos, se puede hipotetizar que las varillas de poliamida 12 pueden haberse visto comprometidas en su resistencia debido a los diversos pasos térmicos necesarios para la incorporación de hidroxiapatita. Además, la edad de las aves puede haber contribuido a los resultados adversos de este estudio. Sin embargo, la investigación futura será necesaria para confirmar tales hipótesis.O presente estudo teve como objetivo avaliar a viabilidade de hastes intramedulares maciças confeccionadas com poliamida 12 e revestidas com hidroxiapatita em úmeros experimentalmente osteotomizados de galos (Plymouth rock branca) jovens. Foram utilizadas 16 aves com 45 dias de vida. Após anestesia geral, foram submetidas à osteotomia transversa completa da diáfise do úmero direito para implantação das referidas hastes que preencheram toda a extensão do canal medular e foram bloqueadas com dois parafusos corticais metálicos em cada fragmento ósseo. A técnica cirúrgica foi facilmente exequível não tendo nenhuma complicação intra-operatória. Por meio de exames clínico e radiográfico, observou-se que logo após o retorno anestésico, seis hastes (37,5%) quebraram próximas ao foco de fratura óssea, sendo o mesmo notado nas demais (62,5%) no 7° dia de cirurgia. Baseado nos dados obtidos pode-se hipotetizar que as hastes de poliamida 12 possam ter tido a resistência comprometida em decorrência das diversas etapas térmicas necessárias para a incorporação da hidroxiapatita. Ademais, a idade das aves pode ter contribuído para os resultados adversos deste estudo. No entanto, pesquisas futuras serão necessárias para confirmar tais hipóteses.       Research, Society and Development2020-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/363510.33448/rsd-v9i7.3635Research, Society and Development; Vol. 9 No. 7; e79973635Research, Society and Development; Vol. 9 Núm. 7; e79973635Research, Society and Development; v. 9 n. 7; e799736352525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/3635/2880Copyright (c) 2020 Fernanda Gosuen Gonçalves Dias, Leonardo Lamarca de Carvalho, Luis Gustavo Gosuen Gonçalves Dias, Vitória Ferreira Nogueira de Paula Fontes, Ewaldo de Mattos Juniorinfo:eu-repo/semantics/openAccessDias, Fernanda Gosuen GonçalvesCarvalho, Leonardo Lamarca deDias, Luis Gustavo Gosuen GonçalvesFontes, Vitória Ferreira Nogueira de PaulaMattos Junior, Ewaldo de2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/3635Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:46.123590Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
