Avaliação morfológica e por imagem radiográfica da matriz óssea mineralizada heteróloga fragmentada e metilmetacrilato, preservados em glicerina para reparação de falhas ósseas em tíbias de coelhos

Abstract: Pesq. Vet. Bras. 33(6):765-770, junho 2013 765 RESUMO.-Os traumas que resultam em fraturas ósseas, principalmente as cominutivas, têm uma importância muito grande na rotina clínico-cirúrgica veterinária e humana. Foi realizada falha segmentar de 6mm na região metafisária medial da tíbia esquerda de 12 coelhos, a qual foi preenchida com implante constituído de matriz óssea mineralizada heteróloga fragmentada e metilmetacrilato, preservados em glicerina (98%) para a sua reconstrução. Foi realizada avaliação… Show more

“…However, this was not observed in this study because before implantation, the composites were completely polymerized, therefore no exothermic reaction occurred at the time of its accommodation in the implantation site. According to Freitas et al 2 and Moreira et al 4 , it was decisive for its full incorporation into the bone defect.…”

“…Furthermore, the composites were stored at 98% glycerin over 30 days, period which, according to Vilela et al 17 and Freitas et al 2 , is long enough for the bactericidal properties of this preservation medium destroy totally the all bacteria present in the implants. If these microorganisms colonize the surgical wound, they would occur the bone lysis and therefore, instability and migration of the composites in the site of transplantation All animals supported the operated limbs immediately in the postoperative period, showing that the tibia structures were not compromised with osteotomy.…”

“…Uma das principais opções para o tratamento dessas afecções é a substituição de um segmento ou o preenchimento de falha óssea, utilizando biomateriais natural ou sintético (Ranzani et al 1996, Alievi et al 2007, Freitas et al 2013. A melhor opção para se tratar as falhas ósseas recai sobre o uso de biomaterial autógeno, ou seja, auto-enxerto, já que acelera a cicatrização óssea.…”
