Desinserção proximal do músculo sartório na correção da luxação patelar medial graus III e IV, em cães

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.

Fixação de fraturas ilíacas em cães com parafusos, fios de aço e cimento ósseo de polimetilmetacrilato

The present study aimed to verify the time for locomotion recovery and bone healing in canine iliac fractures fixated with screws, orthopedic wires and methylmetacrylate bone cement. Sixteen dogs from both genders accidentally hit by a car and showing iliac fractures were included. Dogs aged from 7 months to 11 years and weighted between 1.8 and 16.0kg. Two dogs had bilaterally fractures stabilized, totalizing 18 ilium osteosynthesis performed. The ilium was achieved via lateral approach. The fractures were reduced and on each bone segment was inserted two to three screws connected by a band tension. Over them a mixture of bone cement added with cefalozin was applied as a definitive fixation device. Suture of soft tissues was made as usual. Postoperative evaluations were periodically performed. After 3 months, 15 dogs showed proper use of the operated limb. Radiographic signs of complete bone healing were observed between 60 and 90 days. Stabilization failure occurred in two cases and one of them required another surgery. Both cases showed a good outcome. Based on these results it was possible to conclude that in dogs weighting up to 16.0kg, iliac fracture fixation with screws, orthopedic wires and bone cement is an efficient technique promoting early limb use and complete bone healing as a result of adequate bone stabilization.
