Resumo


Este trabalho tem por objetivo descrever a ocorrência, tipo, intervenções e desfechos das fraturas em potros de até 11 meses, atendidos no Hospital Veterinário da FMVZ-USP entre 2008 e 2019. Nesse período foram atendidos 31 casos, 17 machos e 14 fêmeas. Os ossos acometidos foram: fêmur (25,8%), tíbia (19,4%), metacarpo principal (19,4%), rádio (16,1%), falange proximal (12,9%), úmero e escápula (3,2%, cada). O tipo de fratura mais observada foi Salter Harris tipo II, acometendo sete casos (22,6%) e a fixação interna com placas bloqueadas foi o tratamento mais utilizado (32,3%), seguido de fixador externo e imobilização rígida externa com três casos cada (9,7%). A alta hospitalar foi registrada em 12 animais (38,7%), sendo que três casos submetidos à osteossíntese utilizando placa bloqueada, apresentaram quadro de osteomielite e os implantes foram removidos. Nos casos envolvendo fêmur, escápula e úmero todos os animais vieram a óbito ou foram submetidos a eutanásia por complicações na osteossíntese ou por não terem condições de tratamento. As particularidades e especificidades destes potros devem ser levadas em consideração no momento da avaliação pré-operatória, planejamento cirúrgico, manejo pós-operatório e prognóstico. Objetivando, assim como nos animais adultos, a busca por melhores técnicas e implantes, para que evoluções satisfatórias tornem-se parte de nossa rotina.
