Cimento de Aluminato de Cálcio - Uso em defeitos ósseos induzidos em fêmures de coelhos (Oryctolagus cuniculus) /

Bürger, Camila Paes. January 2010 (has links)
Resumo: O tratamento de não união e união retardada é um desafio constante na rotina do ortopedista veterinário. A dificuldade de se conseguir repouso adequado dos pacientes submetidos à osteossíntese, frequentemente, resulta em consolidações mal sucedidas. Com o objetivo de se avaliar o comportamento do cimento de aluminato de cálcio, foram induzidos defeitos ósseos de 3,57mm de diâmetro nos fêmures de 12 coelhos, sendo os do lado direito preenchidos com o referido biomaterial e os do esquerdo permaneceram vazios. Aos 15, 30 e 60 dias de pós-operatório, realizaram-se avaliações clínico-cirúrgicas, radiográficas e histológicas, a fim de se observar o potencial osteoindutor e osteocondutor do biomaterial no defeito ósseo, e se houve osteointegração. Os resultados evidenciaram que o cimento aluminoso, nesta formulação, não possui esses potenciais e nem poder de osteointegração, possivelmente por possuir porosidade reduzida / Abstract: The treatment of non union and delayed union is a constant challenge for veterinary orthopedists. The difficulty in achieving adequate rest for patients which have undergone osteosynthesis results in unsuccessful bone consolidations. With the aim of evaluating the behavior of a calcium aluminate cement, bone defects of 3,57 mm of diameter were induced in femurs of 12 rabbits. The defects on the right side were filled with the biomaterial and the ones on the left side remained unfilled. The evaluation periods occurred at 15, 30 and 60 days after surgery. Clinical, surgical, radiographic and histological evaluations were performed in order to observe the osteoinductive and osteocondoctive potential of the biomaterial on the bone defects, as well to verify if there was osteointegration. The results showed that the aluminate cement does not have these potencial and nor cause osteointegration in the formulation used in this study / Orientador: Cíntia Lucia Maniscalco / Coorientadora: Paola Castro Moraes / Banca: Julio Carlos Canola / Banca: Gustavo Garkalns de Souza Oliveira / Mestre
