Hock (zoology)
The hock, tarsus or uncommonly gambrel, is the region formed by the tarsal bones connecting the tibia and metatarsus of a digitigrade or 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 vestigial remnant fused to the distal portion of the tibia (as in horses). It is the anatomical 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 domesticated species. Horse The terms ''tarsus'' and ''hock'' refer to the region between the gaskin (crus) and cannon regions (metatarsus), which includes the bones, joints, and soft tissues of the area. The hock is especially important in equine anatomy, due to the great strain it receives when the horse is worked. Jumping, quick turns or s ...

Tibiotarsal Joint
In the anatomy of humans and many other mammals, the tibiotarsal joint is the joint between the tibia and the tarsus (skeleton), tarsus. In bird, avian anatomy, it is the equivalent of the ankle. In equine veterinary science, Synovial joint, synovial distension of the tibiotarsal joint in the horse is known as bog spavin. References Skeletal system {{musculoskeletal-stub ...

Equine Conformation
Equine conformation evaluates a horse's bone structure, musculature, and its body proportions in relation to each other. Undesirable conformation can limit the ability to perform a specific task. Although there are several faults with universal disadvantages, a horse's conformation is usually judged according to its intended use. Thus "form to function" is one of the first set of traits considered in judging conformation. A horse with poor form for a show jumper could have excellent conformation for a cutting horse or draft horse. Every horse has good and bad points of conformation and many horses excel even with conformation faults. Head and neck The standard of the ideal head varies dramatically from breed to breed based on a mixture of the role the horse is bred for and what breeders, owners and enthusiasts find appealing. Breed standards frequently cite large eyes, a broad forehead and a dry head-to-neck connection as important to correctness about the head. Traditional ...

Stringhalt
Stringhalt is a sudden flexion of one or both hind legs in the horse, most easily seen while the horse is walking or trotting. It is most evident when the horse is backing up slowly, turning on the affected leg, or suddenly frightened. It can involve one or both hind legs of the horse. It is a spasmodic contraction of the lateral extensor tendons of the hind legs. There are four forms of stringhalt: *Australian stringhalt: a flatweed (''Hypochaeris radicata'') is the suspected cause *Pseudostringhalt: the apparent result of a painful condition in the affected leg *Unilateral stringhalt: cause unknown, but often relieved by section of the lateral extensor tendon *Bilateral stringhalt: in two out of two affected horses necropsied, abnormal thalamus Treatment varies. Australian stringhalt Australian stringhalt was described and differentiated from classical stringhalt in 1884. Australian stringhalt is differentiated from classical stringhalt by the severity, occurrence of outbreaks, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curb (horse)
Curb is defined in older literature as enlargement secondary to inflammation and thickening of the long plantar ligament in horses.Stashak (1987) ''Adams' Lameness in Horses'', Philadelphia, Lea & Febiger, pp. 715-718, However, with the widespread use of diagnostic ultrasonography in equine medicine, curb has been redefined as a collection of soft tissue injuries of the distal plantar hock region. Curb is a useful descriptive term when describing swelling in this area. Structures affected Besides swelling in the long plantar ligament, injury to the deep digital flexor tendon, superficial digital flexor tendon, tarsocrural lateral collateral ligament or peritendonous / periligamentous tissues in this region can contribute to the appearance of curb. Sickle-hocked conformation is a predisposing risk factor for the development of curb. (See hind leg conformation) Fluid accumulation and/or swelling are almost always found in the peritendonous / periligamentous tissues in curb, often ...

Bone Spavin
Bone spavin is a bony growth within the lower hock joint of horses 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 there is significant bony enlargement over the tarsal bones, 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 u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...

Lameness (equine)
Lameness is an abnormal gait or stance of an animal that is the result of dysfunction of the Animal locomotion, 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 riding, pleasure horses. It is one of the most costly health problems for the Horse industry, 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. Orthopedi ...

Blunt Trauma
A blunt trauma, also known as a blunt force trauma or non-penetrating trauma, is a physical trauma due to a forceful impact without penetration of the body's surface. Blunt trauma stands in contrast with penetrating trauma, which occurs when an object pierces the skin, enters body tissue, and creates an open wound. Blunt trauma occurs due to direct physical trauma or impactful force to a body part. Such incidents often occur with road traffic collisions, assaults, and sports-related injuries, and are notably common among the elderly who experience falls. Blunt trauma can lead to a wide range of injuries including contusions, concussions, abrasions, lacerations, internal or external hemorrhages, and bone fractures. The severity of these injuries depends on factors such as the force of the impact, the area of the body affected, and the underlying comorbidities of the affected individual. In some cases, blunt force trauma can be life-threatening and may require immedia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synovial Bursa
A synovial bursa, usually simply bursa (: bursae or bursas), is a small fluid-filled sac lined by synovial membrane with an inner capillary layer of viscous synovial fluid (similar in consistency to that of a raw egg white). It provides a cushion between bones and tendons and/or muscles around a joint. This helps to reduce friction between the bones and allows free movement. Bursae are found around most major joints of the body. Structure Based on location, there are three types of bursa: subcutaneous, submuscular and subtendinous. A subcutaneous bursa is located between the skin and an underlying bone. It allows skin to move smoothly over the bone. Examples include the prepatellar bursa located over the kneecap and the olecranon bursa at the tip of the elbow. A submuscular bursa is found between a muscle and an underlying bone, or between adjacent muscles. These prevent rubbing of the muscle during movements. A large submuscular bursa, the trochanteric bursa, is found at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
