Background: Flexural deformities are anatomical deviations, in varying degrees, of one or more joints, and may have a congenital or acquired origin. Congenital contracture of the deep digital flexor tendon (DDFT) affects newborn calves and results in hyperflexion of the metacarpal-phalangeal joint, which in severe cases means that the animal must support its own weight on its fetlock joints. The aim of this study is to report the rapid and successful result of applying bilateral total tenotomy technique on a newborn bovine that had been diagnosed with severe bilateral DDFT contracture in the thoracic limbs. Case: A 3-week-old male bovine with a history of difficulty in maintaining a quadrupedal position was attended at the Veterinary Hospital of the Federal University of Tocantins. The animal had severe bilateral locomotor alterations in the thoracic members to the point that he walked on his fetlock joints. The physical examination revealed clinical parameters within the normal range. However, the locomotor system examination showed severe flexor deformity in the bilateral metacarpal-phalangeal joints, and the limbs were being supported on the dorsal face of the fetlock joints, which presented ulcerations, and was suggestive of a shortening of the DDFT. Based on the patients history and clinical examination, as well as the severity of the tendon contractures, surgical treatment using the DDFT bilateral total tenotomy technique was decided upon. Postoperative treatment consisted of 2.5 mg/kg of enrofloxacin intramuscularly (IM), SID, for 5 days and 0.5 mg/kg meloxicam via IM, SID, for 3 days; as well as a dressing (cotton, medical bandage and a PVC mold) on the thoracic limbs to provide support and allow the animal to..(AU)
