Ruptura do ligamento cruzado cranial em um gato: reconstituição com fáscia lata

The cranial cruciate ligament rupture (CCLR) is rare diagnosis in cats and the surgical correction provides a faster return to limb function. A cat with acute lameness and pain on palpation of the right stifle was attended at the Veterinary Hospital of UFSM. The diagnosis of CCLR was performed by positive tibial compression test and positive cranial drawer sign and confirmed by surgery. We chose to perform the reconstruction of the ligament with fascia lata and after of the observe clinical postoperative and in the long-term it was concluded that the technique showed satisfactory results in this case.

Análise biomecânica ex vivo de dois métodos de osteossíntese de ílio em cães

This study evaluated the biomechanical use of cortical allografts preserved in honey for the stabilization of transverse osteotomy of ilium in dogs, as well as the use of wire hemicerclage alone against the bending forces. Thirteen canine were tested bilaterally, where one side was stabilized with bone graft and the other with wire hemicerclage alone. The prototypes stabilized with bone graft were statistically more resistant to strength flexion than those wire hemicerclage used alone. The results showed that the use of cortical bone implants is a viable alternative for fixing the iliac osteotomy in dogs.

Medical infrared imaging and orthostatic analysis to determine lameness in the pelvic limbs of dogs

Subtle lameness makes it difficult to ascertain which is the affected limb. A study was conducted to investigate a change in the thermal pattern and temperature of the thermal image of the paw print in a lame pelvic limb compared to a non-lame pelvic limb of dogs confirmed by orthostatic analysis. Fourteen client owned dogs with a unilateral pelvic limb lameness and 14 healthy employee dogs were examined and the pelvic limbs radiographed. Thermal images of the paw print were taken after each dog was kept in a static position on a foam mat for 30 seconds. Average temperatures and thermographic patterns were analyzed. Analysis was performed in a static position. The asymmetry index for each stance variable and optimal cutoff point for the peak vertical force and thermal image temperatures were calculated. Image pattern analysis revealed 88% success in differentiating the lame group, and 100% in identifying the same thermal pattern in the healthy group. The mean of the peak vertical force revealed a 10.0% difference between the left and right pelvic limb in healthy dogs and a 72.4% between the lame and non-lame limb in the lame dog group. Asymmetry index analysis revealed 5% in the healthy group and 36.2% in the lame group. The optimal cutoff point for the peak vertical force to determine lameness was 41.77% (AUC = 0.93) and for MII 0.943% (AUC = 0.72). The results of this study highlight the change in the thermal pattern of the paw print in the lame pelvic limb compared to a non-lame pelvic limb in the lame group and the healthy group. Medical infrared imaging of the paw prints can be utilized to screen for the lame limb in dogs.

Osteossíntese biológica em tíbia de cão com aplicação de fixador esquelético externo: relato de caso

Osteossintese biologica e o tratamento dado, principalmente, as fraturas cominutivas diafisarias em quenao e possivel a reducao anatomica precisa dos fragmentos osseos, preservando o alinhamento articularsem interferir no suprimento sanguineo local. A fixacao pode ser alcancada atraves de longa ponte na areade fratura usando parafusos bloqueados, placas em ponte ou fixadores esqueleticos externos que levam acicatrizacao do tecido osseo fraturado. Demonstrou-se a utilizacao com sucesso desse principio em cao comfratura cominutiva iatrogenica da tibia causada pela colocacao equivocada do fixador esqueletico externo(FEE). A reintervencao cirurgica com a aplicacao do FEE baseando-se nos principios da osteossintese biologicapromoveu estabilidade aos fragmentos osseos envolvidos e garantiu boa cicatrizacao do tecido.
