Background: It is believed that the inclined tibial plateau angle to be a major cause of cranial cruciate ligament (CCL) rupture, and the treatment of this disease is the tibial plateau leveling for decrease the cranial tibial thrust. However, there are breeds predisposed to rupture of the cranial cruciate ligament and in this patterns breed the tibial plateau is more inclined due to the conformation of the limb. The aim of this communication was to evaluate the effectiveness of the locking screw and cauterizing the growth plate of the tibial plateau as a preventive method of cranial cruciate ligament rupture. Case: In a young dog, one stifle joint randomly chosen for placing a screw in order to block the tibial plateau growth line. There was placed a 3.5 mm x 20 mm cancellous bone screw in the dorsocranial surface of the tibial plateau of the left hindlimb. Two months after the first surgical intervention, the contralateral limb was cauterized in the tibial plateau growth line. Electrocauterization was performed with a spatula electrode set at 60 watts, performing ablation on the cranial third of the tibial plateau physis with access to the medial and lateral surfaces of the proximal tibia. The electrode was placed against the physis for 10 seconds at each site. Both members were followed radiographically to measure the tibial plateau angle and observed the angle reduction. [...](AU)
