SUMMARY:

Surgical correction of cranial cruciate ligament rupture is the most effective form of treatment, with excellent long-term results, depending on the technique used. Tibial plateau leveling osteotomy (TPLO) is one of the most used to correct the resulting instability. The purpose of this research was 1) to develop a mathematical formula to calculate the rotation of the proximal fragment, at values greater than 5 degrees, in TPLO (from 8 to 12 degrees), as well as 2) to evaluate in the vPOP-PRO program what it is the correct angulation of the proximal screws in TPLO plates available on the market and. Five tables were created with final tibial plateau angles (APTf) between 8 and 12 degrees, from initial tibial plateau angles (APTi) ranging between 15 and 50 degrees, and saws with a radius between 8 and 30 mm. Analyzing the tables generated in 40 mediolateral radiographs of dog tibiae, it was observed that there was a statistical difference (p<0.05) between the final angulations expected by the tables and the final angulations obtained in Vpop-pro, in relation to the tibial plateau angle. Proximal screw angulations were tested on 68 radiographic images of dog tibiae in caudocranial projection. All measurements and angulation of the plates in relation to the screws were performed using the vPOP-PRO software. The means of the angulations that the screws should be on the Lincevet® and Fixin® plates were respectively (15.6 ± 4.66 and 14.8 ± 3.97). There was a significant difference in the angle between the two brands (p < 0.05).
