Bog Spavin
Bog spavin is a swelling of the tibiotarsal joint of the horse's hock which, in itself, does not cause lameness. The joint becomes distended by excess synovial fluid and/or thickened synovial tissue bringing about a soft, fluctuant swelling on the front of the joint, as well as in the medial and lateral plantar pouches. Bog spavin is generally an indication of underlying pathology within the joint. Causes Bog spavin is a physical finding, and does not directly create lameness. Causes include synovitis (inflammation of the lining of the joint capsule), degenerative joint disease, or excessive strain of the joint capsule. In horses younger than the age of three, most cases of bog spavin are caused by a defect in the tibiotarsal joint, while in older, fully mature horses, it is most likely because of chronic strain of the joint capsule. Infection of the joint causes a severe synovitis, and should be treated as an emergency. Many horses with bog spavin will not be lame. However, ...

Horse Bog Spavin (1906) (14769128971)
The horse (''Equus ferus caballus'') is a Domestication, domesticated, odd-toed ungulate, one-toed, ungulate, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two Extant taxon, extant subspecies of wild horse, ''Equus ferus''. The horse has evolution of the horse, evolved over the past 45 to 55 million years from a small multi-toed creature, ''Eohippus'', into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication of the horse, domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from equine anatomy, anatomy to life stages, size ...

Tibiotarsal Joint
In the anatomy of humans and many other mammals, the tibiotarsal joint is the joint between the tibia and the tarsus. In avian anatomy, it is the equivalent of the ankle. In equine veterinary science, synovial distension of the tibiotarsal joint in the horse is known as bog spavin Bog spavin is a swelling of the tibiotarsal joint of the horse's hock which, in itself, does not cause lameness.

Hock (zoology)
The hock, or gambrel, is the joint between the tarsus (skeleton), tarsal bones and tibia of a digitigrade or Ungulate, unguligrade quadrupedal mammal, such as a horse, cat, or dog. This joint may include articulations between tarsal bones and the fibula in some species (such as cats), while in others the fibula has been greatly reduced and is only found as a Vestigiality, vestigial remnant fused to the distal portion of the tibia (as in horses).{{citation needed, date=January 2016 It is the anatomical Homology (biology), homologue of the ankle of the human foot. While homologous joints occur in other tetrapods, the term is generally restricted to mammals, particularly long-legged domestic animals, domesticated species. Horse Although the ''tarsus'' refers specifically to the bones and joints of the hock, most people working with horses refer to the ''hock'' in such a way to include the bones, joints, and soft tissue of the area. The hock is especially important in equine anatomy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lameness (equine)
Lameness is an abnormal gait or stance of an animal that is the result of dysfunction of the locomotor system. In the horse, it is most commonly caused by pain, but can be due to neurologic or mechanical dysfunction. Lameness is a common veterinary problem in racehorses, sport horses, and pleasure horses. It is one of the most costly health problems for the equine industry, both monetarily for the cost of diagnosis and treatment, and for the cost of time off resulting in loss-of-use. Causes of lameness Lameness is most commonly caused by pain, but may also be the result of neuromuscular disease or mechanical restriction. Lameness itself is a clinical sign, and not a diagnosis. Pain Pain is the most common cause of lameness in the horse. It is usually the result of trauma or orthopedic disease, but other causes such as metabolic dysfunction, circulatory disease, and infection can also cause pain and subsequent lameness. Orthopedic causes of lameness are very common and may be the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synovial Fluid
Synovial fluid, also called synovia, elp 1/sup> is a viscous, non-Newtonian fluid found in the cavities of synovial joints. With its egg white–like consistency, the principal role of synovial fluid is to reduce friction between the articular cartilage of synovial joints during movement. Synovial fluid is a small component of the transcellular fluid component of extracellular fluid. Structure The inner membrane of synovial joints is called the synovial membrane and secretes synovial fluid into the joint cavity. Synovial fluid is an ultrafiltrate from plasma, and contains proteins derived from the blood plasma and proteins that are produced by cells within the joint tissues. The fluid contains hyaluronan secreted by fibroblast-like cells in the synovial membrane, lubricin (proteoglycan 4; PRG4) secreted by the surface chondrocytes of the articular cartilage and interstitial fluid filtered from the blood plasma. This fluid forms a thin layer (roughly 50 μm) at the surface of c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synovium
The synovial membrane (also known as the synovial stratum, synovium or stratum synoviale) is a specialized connective tissue that lines the inner surface of capsules of synovial joints and tendon sheath. It makes direct contact with the fibrous membrane on the outside surface and with the synovial fluid lubricant on the inside surface. In contact with the synovial fluid at the tissue surface are many rounded macrophage-like synovial cells (type A) and also type B cells, which are also known as fibroblast-like synoviocytes (FLS). Type A cells maintain the synovial fluid by removing wear-and-tear debris. As for the FLS, they produce hyaluronan, as well as other extracellular components in the synovial fluid. Structure The synovial membrane is variable but often has two layers: * The outer layer, or subintima, can be of almost any type of connective tissue – fibrous (dense collagenous type), adipose (fatty; e.g. in intra-articular fat pads) or areolar (loose collagenous type ...

Degenerative Joint Disease
Osteoarthritis (OA) is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone which affects 1 in 7 adults in the United States. It is believed to be the fourth leading cause of disability in the world. The most common symptoms are joint pain and stiffness. Usually the symptoms progress slowly over years. Initially they may occur only after exercise but can become constant over time. Other symptoms may include joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are the two near the ends of the fingers and the joint at the base of the thumbs; the knee and hip joints; and the joints of the neck and lower back. Joints on one side of the body are often more affected than those on the other. The symptoms can interfere with work and normal daily activities. Unlike some other types of arthritis, only the joints, not internal organs, are affe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bone Spavin
Bone spavin is a bony growth within the lower hock joint of horse or cattle. It is caused by osteoarthritis, and the degree of lameness that results can be serious enough to end a horse's competitive career. Description Bone spavin is osteoarthritis, or the final phase of degenerative joint disease (DJD), in the lower three hock joints. It usually affects the two lowest joints of the hock (the tarsometatarsal and the distal intertarsal joints), with the third joint, the proximal intertarsal, being the least likely to develop bone spavin. This condition has various types: jack spavin when lesion on the tarsal and carpal bones is large, and high spavin when the pathology occurs higher in the joint than is typical. Conversely, occult spavin does not produce any significant exostoses on the small tarsals, whilst bog spavin and blood spavin do not involve bony changes. Causes Cartilage compression Excessive compression can cause, over time, the cartilage between the upper and lower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleopathology
Paleopathology, also spelled palaeopathology, is the study of ancient diseases and injuries in organisms through the examination of fossils, mummified tissue, skeletal remains, and analysis of coprolites. Specific sources in the study of ancient human diseases may include early documents, illustrations from early books, painting and sculpture from the past. Looking at the individual roots of the word "Paleopathology" can give a basic definition of what it encompasses. "Paleo-" refers to "ancient, early, prehistoric, primitive, fossil." The suffix "-pathology" comes from the Latin ''pathologia'' meaning "study of disease." Through the analysis of the aforementioned things, information on the evolution of diseases as well as how past civilizations treated conditions are both valuable byproducts. Studies have historically focused on humans, but there is no evidence that humans are more prone to pathologies than any other animal. Paleopathology is an interdisciplinary science, meaning ...

Radiograph
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical radiography ("diagnostic" and "therapeutic") and industrial radiography. Similar techniques are used in airport security (where "body scanners" generally use backscatter X-ray). To create an image in conventional radiography, a beam of X-rays is produced by an X-ray generator and is projected toward the object. A certain amount of the X-rays or other radiation is absorbed by the object, dependent on the object's density and structural composition. The X-rays that pass through the object are captured behind the object by a detector (either photographic film or a digital detector). The generation of flat two dimensional images by this technique is called projectional radiography. In computed tomography (CT scanning) an X-ray source and its associated detectors rotate around the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equine Prepurchase Exam
In horse trading, an equine prepurchase exam is an examination of a horse requested by the buying party prior to the purchase, in order to identify any preexisting problems which may affect a horse's future performance and reduce buyer risk. The inspection usually consists of four phases in which a veterinarian examines all aspects of the horse's health. Role of the veterinarian An equine prepurchase exam is carried out by a veterinarian, who must also have a knowledge of the particular horse's breed, prospective use and competition rules, to best assess a horse's current and future soundness. To determine the relative 'soundness' of the horse, veterinarians assess "the health status of the horse together with medical abnormalities", and should explain and record any medical abnormalities/concerns revealed during the exam. However, they are not guaranteeing the soundness of the horse. Veterinarians should be neutral to both buyer and seller to avoid any future discrepancies. Ass ...
