Evaluating heel support on a tracing of a lateral radiograph. The "x" indicates the center of the coffin joint (a point along the curvature of the joint midway between the most proximal aspects of the extensor process and the dorsal articular surface of the navicular bone). A vertical line is drawn down from this point to intersect with the shoe. At least 40% of the shoe's length should be behind this line.

... evaluate heel support, a vertical line is extended down from the center of the coffin joint to intersect with the shoe (Fig 2). The center of the coffin joint is determined to be the point midway along the curvature of the distal interphalangeal joint, between the proximal extent of PIII's extensor process and the proximal extent of the dorsal articular surface of the navicular bone. ...
Context 2
... rather than drawing a circle over the coffin joint to determine its center, we sim- ply select a point along the curvature of the coffin joint that is equidistant between the most proximal aspects of the extensor process and the dorsal artic- ular surface of the navicular bone. We then drop a vertical line from that point to the ground surface (Fig. 2). Using this method, we consider heel sup- port to be adequate in most horses when no more than 60% of the shoe is in front of this line and no less than 40% of the shoe is behind this line (i.e., 60:40). A common concern among owners and some farriers is that the horse is more likely to loosen or pull off a shoe if the shoe extends ...

O presente estudo tem por objetivo avaliar os cascos e técnicas de casqueamento e ferrageamento de equinos do Grupo 1, compostos de animais da Cavalaria da Polícia Militar e o Grupo 2, animais utilizados em serviços de tração urbana. Com a justificativa de avaliar o conhecimento de tutores sobre manejo podal, verificar práticas utilizadas e enumerar afecções podais comumente encontradas e levar informações a respeito do casqueamento e ferrageamento. Foram selecionados no total de 20 animais, os cascos foram avaliados com um podogoniômetro e fita métrica para obter dados sobre ângulo do talão e pinça, relação de peso corporal por área de casco, classificando-os como encastelados, achinelados ou equilibrados. Os dados foram coletados no intervalo de 10 dias, e também houve coleta de informações sobre quais os materiais e como era realizado o manejo podal, idade, altura e peso dos equinos, e os tutores receberam recomendações. Animais do Grupo 1 possuem maior expectativa de vida, menor jornada de trabalho, possuem cascos equilibrados, concavidade de sola adequada, realizam ferrageamento quinzenalmente por profissionais, usam cravos e ferradura a frio, mas apresentam desvio de angulação contralateral até o grau 2. Equinos do Grupo 2 possuem cascos achinelados, desvios contralaterais até grau 3, maior jornada de trabalho, são casqueados por tutores, utilizam ferraduras de borracha e pregos comuns, utilizam facas para aparar e martelos para fixação de pregos. Portando, é de fundamental importância a informatização aos tutores a respeito da prática adequada de casqueamento e ferrageamento no município de Imperatriz, Maranhão.
Chapter
This chapter presents physical examination descriptions relating to three categories of horses: those with potential laminitis; those with mild lameness; and those horses with typical painful manifestations of laminitis. Equine healthcare professionals along with the horses' owners need to be looking for, recording, and monitoring changes over time: horse's overall body condition and unusual stances, specific hoof changes, and level of pain. Laminitis ought to be on a primary rule-out list for any lame horse. Other physical examination considerations include: systemic effect on the vital signs and foot conformation. The well-documented sepsis cases that are at higher risk of secondary serious laminitis are gastrointestinal medical and surgical cases, pleuropneumonia, and retained placenta cases. The early physical signs of subclinical laminitis are primarily hoof changes of deteriorating quality, sole bruising, and increasing numbers of lesions. Potentially, all horses, sound or lame, need to be considered as having subtle laminitis.

Veterinarian/farrier/owner communication can be difficult in a given lameness case. A small group of veterinarians and farriers discussed the factors complicating this communication. Specific definition of roles; professional respect; differences in required education; distance and driving to horse, fees, and licensure requirements were cited as the primary complicating factors. In conclusion, the group suggested the ideal communication for a specific lameness case was for the veterinarian, farrier, and owner to be present when shoeing was being planned. A telephone call would be second in preference and a written case summary was the third choice. There are suggestions on how to formulate the written summary.
