Osteoss\u00edntese (do grego osteon<\/em> \u2014 osso e s\u00edntese<\/em> \u2014 conex\u00e3o, liga\u00e7\u00e3o) \u2014 \u00e9 um m\u00e9todo cir\u00fargico para alinhamento de fragmentos \u00f3sseos e elimina\u00e7\u00e3o segura de sua mobilidade usando v\u00e1rias constru\u00e7\u00f5es implantadas de metal ou pol\u00edmeros.<\/p>\n\n

Etiologia e fisiopatologia<\/strong><\/h2>\n\n

O principal objetivo biol\u00f3gico da osteoss\u00edntese \u00e9 a cria\u00e7\u00e3o de estabilidade mec\u00e2nica na \u00e1rea da fratura. A fixa\u00e7\u00e3o ideal elimina a menor micromobilidade dos fragmentos. Isso cria condi\u00e7\u00f5es \u00f3timas para a chamada consolida\u00e7\u00e3o \u00f3ssea direta (prim\u00e1ria), que ocorre sem a forma\u00e7\u00e3o de calo cartilaginoso maci\u00e7o.<\/p>\n\n

A osteoss\u00edntese intramedular (interna) envolve a instala\u00e7\u00e3o de fixadores diretamente no osso (placas e parafusos de superf\u00edcie) ou a introdu\u00e7\u00e3o deles no canal medular (hastes de tit\u00e2nio intramedulares). A osteoss\u00edntese externa (trans\u00f3ssea) utiliza dispositivos de fixa\u00e7\u00e3o externa, onde a estrutura r\u00edgida de suporte se encontra fora do corpo do paciente.<\/p>\n\n

Import\u00e2ncia cl\u00ednica<\/strong><\/h2>\n\n

As indica\u00e7\u00f5es m\u00e9dicas absolutas para a cirurgia incluem fraturas expostas, fraturas intra-articulares com deslocamento das superf\u00edcies articulares, fraturas com dano aos vasos sangu\u00edneos principais, bem como politraumatismo grave.<\/p>\n\n

A osteoss\u00edntese de qualidade permite eliminar completamente o uso prolongado de imobiliza\u00e7\u00f5es com gesso. O paciente tem a oportunidade de iniciar a ativa\u00e7\u00e3o precoce e a reabilita\u00e7\u00e3o de movimentos nas articula\u00e7\u00f5es adjacentes, o que previne o desenvolvimento de atrofia muscular, contraturas permanentes e tromboses venosas perigosas.<\/p>\n","protected":false},"excerpt":{"rendered":"
