Diagnóstico da Síndrome Podotroclear em Equinos: alterações radiográficas e ultrassonográficas
(Fundação de Ensino Octávio Bastos, 2022-09-09) TODERO, Larissa M.; RIBEIRO, Camila; ALAYON, Ana Carolina E.; MATIAS, Lizandra C.; REIS, Laysla D.; RODRIGUES, Paulo D.; PESSINATTI, Bárbara D.
Podotrochlear syndrome, also known as navicular bone syndrome, in horses, is characterized by chronic and progressive pain. Its etiopathogenesis is still not fully understood, but the theory of biomechanics is the most defended. Its diagnosis is performed through orthopedic examination, perineural blocks and complementary exams, the most used being radiography and ultrasound. Radiography becomes the exam of choice for confirmation of this syndrome, the projections of choice are lateromedial, dorsoproximalpalmaro/plantarodistal oblique and palmaro/plantaroproximal-palmaro/plantarodistal oblique, better known as Skyline. Among the alterations found in the radiographic examination, there are changes in the size and number of synovial invaginations, sclerosis, loss of corticomedullary definition and cortical erosion. However, not all animals that present clinical signs present radiographic signs, therefore, lesions in soft tissues that make up the podotrochlear apparatus may be involved. Therefore, the ultrasound examination is relevant. The distal palmar/plantar accesses of the hip and the transcuneal approach are performed and the alterations found mainly affect the deep digital flexor tendon, the navicular bursa and the annular ligament of the distal sesamoid bone.
Síndrome da reabsorção odontoclástica e hipercementose equina: Revisão de literatura
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) TODERO, Larissa M.; RIBEIRO, Amanda
Equine odontoclastic resorption and hypercementosis syndrome (EOTRH) is a painful and progressive condition that affects the incisor and canine teeth of geriatric horses. Since its etiopathogenesis has not yet been fully resolved, this disease often ends up being underdiagnosed. Several theories of etiology have been considered for this disease, however, none of them have been fully accepted. Histologically, EOTRH presents with the resorption of tooth structures by odontoclasts, usually followed by the deposition of altered cementum, by odontoblasts, cementoblasts and fibroblasts. To diagnose this syndrome, a detailed clinical oral examination and the use of radiographic examination are necessary, since the signs may often not be visible at the beginning of the disease. Clinical signs are varied, and range from pain and lack of food apprehension with incisors, to more serious changes, such as changes in the angles of the incisors and tooth fractures. On radiographs, it is possible to observe resorption changes in the teeth, with lysis of the reserve crown and root and proliferative changes, such as deposition of cementum and expansion of the alveolar bone. In addition, alveolitis, osteomyelitis and periodontal changes are also found. There is no effective treatment for EOTRH, and extraction of the affected teeth is almost always indicated.
