Estágio no Hospital Clínico Veterinário da Universidade de Zaragoza (Espanha) e ruptura do ligamento cruzado cranial em cães – descrição de três casos clínicos

Abstract

This clinical internship was carried out in Zaragoza within the framework of cooperation between the University of Zaragoza and Eduardo Mondlane University, from May 15 to July 15, with the aim of deepening the theoretical and practical knowledge obtained during training at Eduardo Mondlane University. The activities were carried out in the companion animal clinic and on large animals (horses). During the period, the intern was accompanied by professors and residents of the hospital unit. During the internship period, routine activities of the hospital unit were monitored, and three cases of rupture of the cranial cruciate ligament were described in 5-year-old male Mastiff dogs; Podenco Andaluz, female, 10 years old and Mixed Breed, male, 10 years old, all castrated, treated at the Veterinary Clinical Hospital and named patient 1, 2 and 3 respectively. The complaints from the owners were lameness and lack of support in the hind limbs, with two patients having left limbs and one right limb. Hematological tests were performed for diagnosis; biochemical; specific by observation, palpation, cranial drawer test, tibial understanding and radiographs. After confirmation of rupture of the cranial cruciate ligament (CCL), the treatment instituted for all three was surgical, using the techniques of closing cranial wedge osteotomy (CCWO) and tibial plateau leveling osteotomy (TPLO) to reduce the excessive angles. Locking plates were used to fix the osteotomies and the postoperative angles obtained for the three patients were 6°, 4° and 8°. The prognosis was favorable as the patients were able to put weight on their limbs two weeks after surgery.
