Foram mensurados os ângulos das AMF de 108 animais, (64 machos e 44 fêmeas), da raça Brasileiro de Hipismo e mestiços da raça, provenientes da Polícia Militar de Minas Gerais (PMMG). Estes foram separados em três grupos, segundo a idade, não apresentando diferença entre os grupos, quando considerados os valores angulares médios da AMF. Somente três animais (um do grupo entre 8 e 12 anos e dois do grupo > 13 anos) se destacaram dos demais, apresentando ângulos das AMF inferiores a 1460. Essa reduzida taxa de prevalência pode ser explicada pela acurada seleção dos animais para a reprodução. Adicionalmente avaliou-se a presença de acúmulos de PG em amostras de LS (n=28) de mestiços da raça Mangalarga Marchador provenientes de abatedouro. Embora não fosse observada diferençasignificativa entre as faixas etárias, os acúmulos de PG predominaram nas amostras provenientes de animais do grupo > 13 anos, demonstrando discreto aumento de acúmulos de PG com o avanço daidade. Igualmente, nos LN (n=15), provenientes de animais da PMMG, considerados suspeitos de serem portadores de DDSAMF, que foram divididos em duas faixas etárias, demonstraram predomínio de acúmulo de PG no grupo > 15 anos, com igualdade estatística para o grupo 13 years), detached from the rest, presented MPJ angles lowerthan 1460. Such a reduced prevalence tax may be explained by the accurate selection of animalsdestined to reproduction. In addition, the presence of proteoglycans (PG) accumulation wasevaluated in samples of suspensory ligaments (SL) (n=28) from animals of abattoir, consideredsuspicious, all mixed-breed Mangalarga Marchador. Although there were observed no significantdifference between the groups, PG accumulation was predominant in the samples of SL, derivedfrom animals of the 13 years group, demonstrating a relation between the presence of PGaccumulation and advancing of age. In the same way, the NL (n=15) from the animals owned byMPMG, considered suspicious of DSLD, that were divided in two groups by age, didnt present adifference among the groups, beside the predominance in the group with more than 15 years. Therewas positive correlation between the PG presence in NL samples and the clinical signs of dorsalMPA angle reduction, proving the systemic nature of DSLD, as observed by Halper et al. (2006).The histological exam of the suspensory and the nuchal ligaments can be considered acomplementary method of DSLD diagnosi

Didatic approach of ultrasonographic examination for evaluation of the carpal joint in horses

<div><p>ABSTRACT: The carpus is a complex articulation, which is often involved in injuries in equine athletes. The objective of this study was to suggest a didactic approach for ultrasonography training for the examination of the carpal joint in horses. Ultrasonograhy examination was performed in a healthy 14-year-old horse. The images were compared with those of a dissected anatomic specimen of the carpal region of a senior horse and with those reported in the literature. Identifiable structures were as follows: (dorsal) tendon of the muscle extensor carpi radialis, tendon of the muscle extensor carpi obliquus, tendon of the muscle commom digital extensor, dorsal synovial outpouchings, joint capsule and fat cushion, (lateral) tendon of the muscle lateral digital extensor, lateral collateral ligament (deep and superficial components), (medial) medial collateral ligament (deep and superficial components) and (palmar) palmar intercarpal ligament, carpal sheath, carpal tunnel, superficial digital flexor tendon, proximal origin of the deep digital flexor tendon, and palmar carpal ligament. Prior knowledge of the anatomy in combination with the study of anatomical specimens is essential for recognizing musculoskeletal structures during ultrasound examination, contributing to the training and learning processes.</p></div
