RESUMO

Background: Craniomandibular osteopathy is a bone disorder that occurs in dogs but is not very commonly reported. It is characterized by a non-neoplastic bilaterally symmetrical irregular proliferation of skull or long bones. Immature dogs are most commonly reported with age ranging from three to eight months. The aim of this paper is to report a case of CMO in a West Highland White Terrier.Case: A 5-month-old entire West Highland white terrier was referred to the Veterinary Hospital with sudden history of severe pain and mandibular swelling, dysphagia, lethargy and weight loss. On physical examination the dog was quiet, alert and responsive. There was thickening of the mandibular bodies with pain at palpation and when opening the mouth. Complete blood count was within normal range. Simple radiographs demonstrated discrete and active new bone formation on the ventral aspect of the mandibular body. Carprofen, dypirone and tramadol were prescribed twice daily for 10 days. 30 days later new radiographs showed more extensive areas of periosteal proliferation advancing to the temporomandibular joint and progression of the looseness of the characteristic compact appearance of lamellar bone of the mandible. The dog was more lethargic, not eating well and in pain. Medication was again prescribed but the treatment was unsuccessful. The dog returned for consultation with severe pain...

RESUMO

Background: Cranial cruciate ligament (CCL) rupture is one of the most common causes of lameness in dogs. It is usually reported to be of traumatic origin in juvenile dogs, associated with hyperextension and excessive internal rotation of the knee joint. Treatment of immature dogs poses a therapeutic dilemma, because various stabilization techniques could prove inadequate for growing animals. Proximal tibial epiphysiodesis has been proposed for the correction of CCL rupture in immature dogs and involves reducing the tibial plateau angle via partial fusion of the proximal tibia. This report aimed to describe the successful treatment of a juvenile dog with CCL rupture using proximal tibial epiphysiodesis.Case: A 5-month-old dog of the American Staffordshire breed presented with a history of claudication in the left pelvic limb since a week after trauma. During physical examination, the dog exhibited a non-weight-bearing lameness and pain on hyperextension of the knee joint; there were no signs of joint effusion. The drawer and cranial tibial thrust tests were positive only with the knee flex, which was confirmed under sedation. The radiograph showed no change in the affected joint and the tibial plateau angle (TPA) was 22. The patient was suggested exploratory arthrotomy. Proximal tibial epiphysiodesis was performed on confirming partial rupture of the CCL. A 3.5 × 30-mm cortica...


A ruptura do ligamento cruzado cranial (LCCr) é uma das causas mais comuns de claudica- ção em cães [6,14]. A lesão ligamentar pode ser de origem aguda, devido a trauma direto ou, na maioria das vezes, devido à degeneração crônica do ligamento [13]. Ainda que grande parte das insuficiências de LCCr ocorram em cães adultos, a ruptura de LCCr é também relatada em cães jovens, muitas vezes associada à avulsão de inserção do ligamento. Estes cães imaturos tornam-se um dilema terapêutico porque muitas técnicas de estabilização podem ser inadequadas para animais em crescimento [4]. Efeitos positivos produzidos pela osteotomia de nivelamento do platô tibial (TPLO) em rupturas de LCCr foram demonstrados [1,12,17]. No entanto, devido à abertura da placa de crescimento, a TPLO não é indicada em cães imaturos. A técnica de osteotomia em cunha da tíbia (TWO) reduz o ângulo do platô tibial (APT) quando aplicada distal a placa de crescimento de cães imaturos, porém, é um procedimento bastante invasivo e com complicações pós-operatórias relatadas [11]. A técnica de epifisiodese proximal da tíbia foi descrita como terapia para a correção da ruptura de LCCr em cães imaturos, com redução do platô tibial através da fusão parcial da tíbia proximal [16]. O objetivo deste relato é descrever o tratamento bem sucedido de um cão jovem com ruptura de LCCr tratado com a técnica de epifisiodese tibial...
