The distal sesamoid bone, also known as navicular bone, is located inside the hoof, palmar (thoracic limbs) or plantar (pelvic limbs) to distal interphalangeal joint. Its extremities are fixed by collateral medial and lateral sesamoidean ligament and distal impar sesamoidean ligament. Navicular disease diagnostic is made through a thorough clinical exam, nerve blocks and imaging exams. Even though imaging exams are not conclusive, they are essential to evaluate the extension of soft tissue lesions. Radiographic projections used to evaluate navicular bone are lateromedial (LM); dorsoproximal-palmaro/plantarodistal oblíqua (D30Pr-PaDiO); dorsoproximal-palmaro/plantarodistal oblíqua (D60Pr-PaDiO) e a palmaro/plantaroproximal-palmaro/plantarodistal oblíqua (PaPr-PaDiO). This exam allows to identify number and shape alterations of synovial invaginations on the distal (foramem nutricio) in the distal margin of distal sesamoid, osteophytes, enthesophytes and periarticular lesions. There are four ultrasonographic accesses described in literature to evaluate podotroclear apparatus, they are: palmar or plantar distal do the pastern, through the heel bulbs, through coronary band and transcuneal. These images allow a beeter the evaluation of soft tissue next to the distal sesamoid, because it is more sensitive than radiographic exam to evaluate acute lesions in soft tissues and perioesteum

A análise termográfica é uma tecnologia proveniente da engenharia e utilizada na Segunda Guerra Mundial para detecção de forças armadas inimigas. Foi aplicada inicialmente na medicina para avaliação de articulações com artrites e hoje apresenta importante função no diagnóstico de câncer de mama em mulheres. Na medicina veterinária, há mais de trinta anos é técnica de diagnóstico auxiliar na clínica de equinos, para avaliação de processos inflamatórios tais como tendinites, desmites, artrites, miosites ou ainda no diagnóstico de fraturas, lesões na coluna ou em nervos periféricos. Por ser uma técnica com alta sensibilidade, exige que seu operador tenha treinamento e doutrinamento, não só para a execução dos exames, mas também para a análise de seus resultados. Diante disso, muitos pesquisadores afirmaram que os exames termográficos de aplicabilidade científica deveriam ser realizados em local com temperatura controlada, em torno de 23oC. Ao se trabalhar com equinos, torna-se difícil encontrar ambientes amplos o suficiente e com controle de temperatura para que os exames sejam feitos, o que praticamente inviabilizaria o uso da termografia na pesquisa com cavalos. Assim, este trabalho propôs um método de padronização das temperaturas que permite realizar termografias de extremidades de membros em ambientes variando entre 18 e 35oC. O método proposto, nomeado como PadTemp, foi validado em cavalos saudáveis e aplicado em experimentos de verificação de eficácia de fármacos e de acompanhamento de cirurgias ortopédicas.

Laminitis is still a major cause of lameness in horses, causing damage to many interested in it. It has been long studied, but there are several points that are not yet fully understood. Doubts about its pathogenesis end up extending at the treatments. Just as there are several theories that attempt to explain the mechanisms of its development, also appear treatments that are sometimes contradictory and inconsistent. Mostly times, laminitis is a consequence of another disease process that occurs systemically in the body. Among them are the main grain overload and processes that cause the animal to the table of endotoxemia, strangled colic, metritis with retained placenta and pleuropneumonia. The proposed treatments include the use of anti-inflammatory drugs, cryotherapy, use of vasodilators and correction of Starling forces, and other measures to support the frog. The stall should be bedded deeply with sand or other material that provides support to the frog

Pain control is an important aspect of equine medicine. Musculoskeletal and gastrointestinal diseases are the most important clinical and surgical painful situations in this specie. In these cases, opioids have been used successfully for the treatment of pain, administered both local (intra-articular and epidural) and systemically. Otherwise, opioids, specially mu agonists like morphine, present important side effects in horses. Amongst these effects, CNS stimulation with increased motor activity and impairment of intestinal motility are observed in several cases. Therefore, adequate dosing of administration are essential for the safe use of opioids in horses

One of the main causes of incapacity in athletes, be they human or equines, is the occurrence of intra-articular lesions. The equines are each time more required in his athletic performance, resulting in intense stress to the structures that composes the locomotor device. The leading cause of human and equine athlete’s functional incapacity is the intra-articular disorders. One of the greatest advances in sports medicine was the development of arthroscopy as a minimal invasive intra-articular surgery. The defining characteristic of diagnostic or surgical arthroscopy is featured by minimal tissue damage and broad inspection of internal structures inside the joint associated with low morbidity and complications. The advantages of surgical arthroscopy over traditional surgery are well known: limited hospitalization, early return to competition, lower risks of post-operative joint rigidity, magnification of inspected structures, joint lavage associated or not with removal of potentially dangerous substances. Arthroscopy cannot replace conventional methods and must not do so; however, the intrinsic limitations of conventional diagnostic techniques, such as radiology and synovial fluid analysis, must be kept in mind, particularly in evaluating damage to cartilage and the synovial membrane. Arthroscopy has now become the accepted method of performing all joint surgery, however it is mainly used for radical surgery, such as osteochondral fragment removal, surgical curettage and arthroplasty

Articular cartilage is the structure that coats the bone ends in regions where two bones are articulated, allowing movement. It has inefficient intrinsic and extrinsic mechanisms of repair, usually resulting in fibrocartilage formation after injury. Such repair have lower strength, stiffness and usability features when compared to hyaline cartilage. The mesenchymal stem cells have the potential to regenerate tissue without the production of scar, and because of this feature it is well studied. But to have its maximum chondrogenic potential, it is necessary to use scaffolds and growth factors. Biomaterials play the role of scaffold for the cells allowing them to become attached, grow and produce extracellular matrix, leading to formation of repair with hyaline cartilage. In this sense, the purpose of this study is to provide information on the various studies using cell therapy and / or biomaterials to produce hyaline cartilage

The equine anesthesia is proven to be a high risk procedure, for both patient and anesthetist, compared to other animal species. In these conditions, a good anesthetic protocol that can deliver sedation, making access and manipulation easier, analgesia fair enough to realize cirurgical procedures, and minimal physiologic changes would be ideal. Since there aren’t any drugs suporting all these qualities, the Neuroleptoanalgesic Associations show themselves as a valuable technique to provide anesthetic quality and safety, possibly diminishing our drug of choice’s doses, therefore offering less fisiological changes and easier monetary access in some cases. This paper objective was to list all these associations found in literature, evaluating their advantages and practical applications
