RESUMO A osteomielite é um desafio terapêutico em ortopedia, capaz de retardar ou mesmo impedir a consolidação óssea. O omento, há anos, tem sido empregado como alternativa em diferentes procedimentos cirúrgicos, por sua capacidade, entre outras, de angiogênese, sendo aplicado na ortopedia veterinária quando há o risco de não união óssea. Neste caso, um cão Fila Brasileiro foi submetido à realização de enxerto com retalho pediculado de omento maior, após osteomielite resistente presente em osteossíntese de fratura múltipla de tíbia aberta grau II. Durante 16 dias, manteve-se a comunicação do retalho, mas, diante do risco de peritonite, o pedículo foi seccionado. Numa sequência de intervenções cirúrgicas, após 89 dias, houve cicatrização óssea e remissão da osteomielite, mesmo na presença de bactérias multirresistentes. Neste relato, o omento foi efetivo como terapia adjuvante no tratamento da osteomielite e garantiu o retorno da função do membro.

ABSTRACT Osteomyelitis is a therapeutic challenge in orthopedics, capable of delaying or even preventing bone healing. The omentum has been used in different surgical procedures as an alternative for its capacity, among others, of angiogenesis, being applied in veterinary orthopedics, when there is a risk of non-union of bone. In this case, a Brazilian row dog was submitted to grafting with pedicle flap of greater omentum, after resistant osteomyelitis present in open fracture osteosynthesis of open tibia grade II. For 16 days the communication of the flap was maintained, but at the risk of peritonitis, the pedicle was sectioned. In a sequence of surgical interventions, after 89 days, there was bone healing and remission of osteomyelitis, even in the presence of multi-resistant bacteria. In this report, the omentum was effective as adjuvant therapy in the treatment of osteomyelitis and guaranteed the return of limb function.

Six surgical corrections were performed with techniques of bone and soft tissue reconstruction, according to the individual presentation of each patient, in four Toy breed dogs, which had grades III and IV luxation, two of them bilaterally operated. During the recovery excessive medial tension associated to the Sartorius muscle was detected, which motivated its release at the iliac insertion. The animals had a functional recovery of the limb after 15 days, and complications or loss of function related to the release of the Sartorius muscle were not observed even after six months. It is believed that the proximal disinsertion of this muscle can be necessary and effective in some patients as a complementary technique to release medial tension in dogs with grades III and IV medial patellar luxation.
