Desenvolvimento de modelo animal in vivo para vertebroplastia percutânea

Abstract

RESUMO: A vertebroplastia percutânea (VP) é um procedimento minimamente invasivo realizado frequentemente em medicina humana para tratamento de fracturas vertebrais, através da injecção de um cimento ósseo. O teste de novos biomateriais depende de modelos animais adequados. O objectivo deste estudo foi desenvolver um modelo de vertebroplastia em ovinos que fosse reprodutível e seguro. No estudo ex vivo a vertebroplastia foi realizada através de um acesso parapedicular bilateral modificado em 24 vértebras lombares de ovino, divididas em 4 grupos. O cimento utilizado num grupo de controlo foi o Cerament™ (Bone Support, Lund, Sweden). No grupo experimental foi testado um novo compósito – Spine-Ghost – que consiste numa matriz de sulfato de cálcio enriquecida com partículas micrométricas de um vidro bioactivo mesoporoso. Todas as vértebras foram analisadas por micro-TAC e submetidas a testes mecânicos de compressão. Para o estudo in vivo, 16 ovelhas foram aleatoriamente divididas em dois grupos – controlo e experimental – e submetidas a VP, utilizando os mesmos cimentos do ex vivo. Todas as vértebras foram analisadas post-mortem por micro-TAC e histologia.
