Resumo
Realizaram-se 25 artrodeses em 21 casos, quatro em gatos e 17 em cães, utilizando hidroxiapatita sintética como substituto ao enxerto ósseo autógeno esponjoso fresco, sendo oito na articulação do carpo, 10 na articulação do tarso, seis na do cotovelo e uma na do joelho. As avaliações radiográficas foram realizadas aos 30 dias em um animal, aos 45 dias em outro e aos 60 dias nos 19 casos restantes. Visibilizou-se união óssea em 24 artrodeses e a não-união em um cotovelo foi atribuída a falha na estabilização. O retorno à função do membro foi classificado de bom a excelente em 22 casos. A hidroxiapatita foi capaz de viabilizar o crescimento ósseo e mostrou-se factível para utilização na prática cirúrgica rotineira em pequenos animais.
Twenty-five arthrodeses were performed in four cats and 17 dogs using synthetic hydroxyapatite as fresh autogenous graft cancellous bone substitute. Arthrodesis was performed in the carpal joint in eight cases, in the tarsal joint in 10, in the elbow joint in six, and in the knee joint in one case. The mean radiographic follow-up time was 30 days in one animal, 45 days in another animal and 60 days in the 19 remaining cases. Bone union was observed in 24 arthrodeses. Non-union of one elbow arthrodesis was due to failure of stabilization. Restoration of limb functionality was classified as good to excellent in 22 cases. Hydroxyapatite was able to promote bone growth and is suitable for using in routine surgical procedures for small animals.
