| Abstract | |
The propose of the study was to compare the effectiveness of eight different methods of protection of the popliteal artery, fibula, tibial and fibular nerves after TPLO osteotomy. 40 canine corpses (80 knees) with body weight 25,9±3,7Kg were separated in eight experimental groups. In the first group, denominated G1 was used a surgical sponge in the craniolateral aspect of the proximal tibial. In G2 the surgical sponge was allocated in the caudolateral aspect of the proximal tibial. In G3, the surgical sponge was applied in the craniolateral aspect, but it was pushed through caudally to the tibia until it being visible in the operative field. The special retractors I and II developed by the team for this purpose were used in groups G4\G5 and G7\G8, respectively. In G4 and G7, the retractor was used in the craniolateral direction and in G5 and G8, in the caudolateral aspect of the proximal tibial. In G6, the trans cortex osteotomy was partially performed and completed with digital pression. The evaluations were performed through radiographic comparison before and after osteotomy and by dissection of the structures adjacent to the osteotomy line. The images were prepared and sent to 4 evaluators for damage graduation in 3 degrees. A 20% of total incidence of injuries was found with 13,8% of grade 2 injuries and 6,2% of grade 3 injuries. Of grade 2 injuries, 81,8% and 60% of grade 3 injuries were identified when protective methods were used. Despite the higher incidence of injury when protective methods were used, this difference was not significant (p>0,05). The protection methods that were used in the cranial to caudal direction were the ones that showed the worst results and the type II retractor in the caudal to cranial direction was the one which least harmed the evaluated structures, but this behavior was also not significant. Due to the conditions of the study, it is concluded that the use of these methods does not bring benefits to the popliteal artery, fibula and tibial and fibular nerve protection during TPLO. (AU) | |
