Abstract(s)
A laminite permanece como uma das patologias mais enigmáticas e prevalentes em cavalos,
exacerbada pela anatomia intrincada do casco e pelas inúmeras forças a que é submetido. O
deslocamento da falange distal dentro do casco manifesta-se como rotação dorsal, deslocamento
distal simétrico e deslocamento distal assimétrico. Apesar de anos de estudo sobre sua fisiopatologia,
os investigadores continuam a deparar-se com descobertas contraditórias. Embora tenham sido
utilizados vários modelos de indução, a compreensão dos mecanismos exatos continua a ser um
desafio. No entanto, surgiu um consenso em torno de três modelos principais: laminite relacionada à
sepsis (SRL), laminite dos membros de suporte (SLL) e laminite endocrinopática (EL), sendo esta última
a mais prevalente. A radiografia desempenha um papel fundamental no diagnóstico, com avanços nas
tradicionais vistas latero-mediais e passando também a incluir vistas horizontais dorsopalmares e
dorsais obliques palmorodistais proximais a 45°. A relação entre veterinários e ferradores é crucial no
contexto da laminite, o tratamento individual de cada paciente é um dos pontos-chave. Nos últimos
anos, assistiu-se a um aumento da investigação sobre tratamentos mecânicos, que gradualmente
suplantaram as modalidades mais antigas, enquanto os métodos de aparagem permaneceram
praticamente inalterados. Os novos modelos de ferraduras, como as de carril oscilante, de biqueira
enrolada, de apoio com sola de espuma (também conhecida como ferraduras “ultimate”) e
moduláveis, termoplásticos, colados, com suporte de rã, oferecem promissoras oportunidades de
intervenção.
Laminitis remains one of the most enigmatic yet prevalent pathologies in horses, exacerbated by the intricate anatomy of the hoof and the multiple forces it encounters. The displacement of the phalanx distalis within the hoof presents as dorsal rotation, symmetric distal displacement, and asymmetrical distal displacement. Despite years of study into its pathophysiology, researchers continue to wrestle with conflicting findings. While numerous induction models have been employed, elucidating the precise mechanisms remains challenging. Nevertheless, consensus has emerged around three primary models: Sepsis-related laminitis (SRL), supporting limb laminitis (SLL), and endocrinopathic laminitis (EL), with the latter being the most prevalent. Radiography plays a crucial role in diagnosis, with advancements beyond traditional lateral-medial views to include horizontal dorsopalmar and dorsal 45° proximal palmorodistal oblique views. The relationship between veterinarians and farriers is central in the context of laminitis, and one of the key points is the individual treatment of each patient. Recent years have attested a surge in research on mechanical treatments, gradually supplanting older modalities while trimming methods remain largely unchanged. New shoe designs, such as rocker rail shoes, rolled toe shoes, foam sole support shoes (also known as "ultimate '' shoes), and mouldable, thermoplastic, glue-on, frog-supportive shoes, offer promising avenues for intervention.
