Is It Orthopaedic Or Neurologic? Sorting out Lameness, Paresis and Dogs That Won’T Get Up
IS IT ORTHOPAEDIC OR NEUROLOGIC? SORTING OUT LAMENESS, PARESIS AND DOGS THAT WON’T GET UP Christopher L. Mariani, DVM, PhD, DACVIM (Neurology) Associate Professor of Neurology & Neurosurgery College of Veterinary Medicine North Carolina State University Lameness, difficulty walking, and reluctance or inability to rise are common presentations for patients presented to small animal practitioners. Disorders of the central and peripheral nervous systems, spine, long bones, joints, tendons, or musculature can all result in these clinical signs. Identifying the organ system and anatomic structures responsible are critical to recommending subsequent diagnostic testing, therapy, and possibly referral to the appropriate specialist. The most critical steps in this evaluation are careful observation of the animal’s gait, and thorough neurologic and orthopedic examinations. CLINICAL EVALUATION Gait Examination Gait examination is arguably the most important part of the evaluation of patients with difficulty ambulating, but is often not performed by veterinary practitioners. The patient should be evaluated while walking towards and away from the examiner, and should also be observed from the side. If the animal is unable to stand or bear weight, adequate support of the limbs in question should be provided while assessing the ability of the animal to voluntarily advance its limbs, bear weight, and move in a coordinated manner. Several abnormalities may be detected with the gait examination. These include: Ataxia: incoordination characterized by a failure to walk or move the limbs in a straight line, crossing of the limbs over the body midline, and possibly stumbling and falling. Ataxia indicates neurologic dysfunction, and may be caused by involvement of several areas of the nervous system. -

EQUINE LAMENESS Dr Annemarie Farrington a Lame Horse Is Defined
EQUINE LAMENESS Dr Annemarie Farrington A lame horse is defined as having an abnormal gait or an incapability of normal locomotion. The commonest causes of lameness in horses include infection (e.g., subsolar abscess), trauma, congenital conditions (e.g., contracted tendons), and acquired abnormalities (e.g., osteochondritis dissecans). Factors unrelated to the musculoskeletal system such as metabolic, circulatory, and nervous system abnormalities (e.g., wobbler syndrome) can also cause a horse to become lame. Lameness resulting from musculoskeletal abnormalities is the leading cause of poor performance in athletic horses and thus the ability to diagnose and treat lameness is an important technique in veterinary medicine. The timely and accurate evaluation of lameness requires a detailed knowledge of the horse’s anatomy, biomechanics, conformation, breed characteristics and an ability to assess a variety of gaits – ie walk, trot, canter.. More lameness is seen in the forelimbs than the hindlimbs and almost 95% of forelimb lameness occurs from the knee down. When the hind limb is involved, however, many more problems are seen in the upper part of the limb, especially in the hock or stifle.. However accurate lameness diagnosis may not always be as straightforward as it seems so a methodical approach must be employed. It is always important to start a lameness examination with a complete history of the lameness, a general physical examination of the horse to rule out other, potentially more serious diseases, and a thorough conformation assessment. The horse’s gait or movement must then be evaluated initially while walking but then trotting both in a straight line and in a circle. -
Recent Advances in Equine Osteoarthritis Annette M Mccoy, DVM, MS, Phd, DACVS; University of Illinois College of Veterinary Medicine
Recent Advances in Equine Osteoarthritis Annette M McCoy, DVM, MS, PhD, DACVS; University of Illinois College of Veterinary Medicine Introduction It is widely recognized that osteoarthritis (OA) is the most common cause of chronic lameness in horses and that it places a significant burden on the equine industry due to the cost of treatment and loss of use of affected animals. Depending on the disease definition and target population, the reported prevalence of OA varies. It was reported at 13.9% in a cross-sectional survey of horses in the UK, but at 97% (defined by loss of range of motion) in a group of horses over 30 years of age. Among Thoroughbred racehorses that died within 60 days of racing, 33% had at least one full-thickness cartilage lesion in the metacarpophalangeal joint, and the severity of cartilage lesions strongly correlated with a musculoskeletal injury leading to death. The majority of the horses in this study were less than 3 years of age, emphasizing the importance of OA in young equine athletes. Unfortunately, a major challenge in managing OA is that by the time clinical signs occur (i.e. lameness), irreversible cartilage damage has already occurred. Although novel treatment modalities are being tested that show promise for modulation of the course of disease, such as viral vector delivery of genes that produce anti-inflammatory products, there are no generally accepted treatments that can be used to reliably reverse its effects once a clinical diagnosis has been made. Thus, there is much research effort being put both into the development of improved diagnostic markers and the development of new treatments for this devastating disease. -

CELLULITIS by Drs Georgina Johnston and Allison Stewart
CELLULITIS by Drs Georgina Johnston and Allison Stewart Dr Georgina Johnston BVetMed BSc (Hons1) MRCVS Georgina is an experienced equine vet and is currently completing speciality training in Equine Sports Medicine and Rehabilitation at the University of Queensland Equine Specialist Hospital. Her clinical interests include lameness investigation, diagnostic imaging, cardiology and exercise testing. Georgina is also an FEI vet. What is cellulitis? Cellulitis can be a frustrating and challenging condition to treat. It is caused by a bacterial infection of the soft tissues under the skin. In horses, it is most commonly found in one of the hind legs but can occur anywhere in the body. Cellulitis is typically first noticed as sudden swelling that is hot and painful to the touch. As the infection worsens, the horse may develop a fever or become lame to the point of not wanting to bear weight on the affected leg. Swelling can spread from the initial site of infection to affect the entire leg. The infection spreads throughout the tissue causing massive swelling. The lymphatics (fine vessels that return tissue fluid or “lymph” back to the circulatory system) are overwhelmed or compressed by the swollen tissue and this results in additional swelling from oedema (non-infected tissue fluid). Cellulitis is very painful, while oedema is non-painful and can be diagnosed by making an impression of a finger in the swollen tissue without any pain response from the horse. It can however be difficult to distinguish exactly which parts of the swollen limb are due to the primary cellulitis and which parts are due to the secondary oedema. -

Pottoka´S Behaviour and Training
POTTOKA´S BEHAVIOUR AND TRAINING The horse’s long evolution as a prey animal has selected a series of behaviours, including social behaviour, that are surprisingly uniform despite great differences in race, climate and geographical conditions. Ethology is the study of animal behaviour under natural conditions, that is, wild, not domestic, animals. Until very recently it was thought that the only true wild horse was Przewalski’s, the Asiatic wild horse (Equus przewalskii). Unfortunately most examples live in zoos, although a herd has been re-introduced to natural conditions in Mongolia where its behaviour is being studied. Wild Equus caballus, the modern horse, was thought to be extinct. Almost all “wild” horses are in fact feral, that is, descendents of escaped domestic horses. During domestication, certain characteristics useful to man are selected: docility, ease of training, strength or speed, the capacity to accept often rather rough handling without protest, the acceptance of unnatural living conditions, or any other whim that takes our fancy, like shape of head or coat colour. It should be noted that ease of training does not necessarily mean intelligence, for our training methods are often confused and anthropomorphic. North American mustangs and island ponies, South American criollos living wild, Australian and New Zealand brumbies, Namibian desert horses, Japanese misaki horses and others, including the famous Tour du Valat herd of Camargue ponies, are all feral horses whose behaviour has been studied. Recently, however, it has been found that the Portuguese Sorraia, which now lives in domestic conditions, is in fact a true wild horse dating from the Palaeolithic. -

The Effect of Loading Upon Hoof Wall Growth and Hoof Shape in the Thoroughbred Foal
The effect of loading upon hoof wall growth and hoof shape in the Thoroughbred foal by Simon John Curtis A thesis submitted in partial fulfilment for the requirements of the degree of Doctor of Philosophy at the University of Central Lancashire in collaboration with Myerscough College February, 2017 Declaration Concurrent registration for two or more academic awards: I declare that while registered as a candidate for the research degree, I have not been a registered candidate or enrolled student for another award of the University or other academic or professional institution. Material submitted for another award: I declare that no material contained in the thesis has been used in any other submission for an academic award and is solely my own work. Signature of Candidate; Type of Award; Doctor of Philosophy School; School of Sport and Wellbeing i Abstract The hoof wall is adapted to take most of the weight-bearing of the foot and is anisotropic and homogeneous. Foals appear to be born with symmetrical paired feet which by maturity are frequently unequal in angle and width. They stand within minutes of birth subjecting the hoof wall to loading. Hoof growth rate and hoof compression may be factors affecting hoof shape. The effect of conformation changes during maturation upon loading and differential hoof growth was unknown. The aims were to; quantify and evaluate the epidermal structure, hoof growth rate, hoof renewal, dorsal hoof wall angle, plastic hoof compression, and hoof loading, during paediatric development. Hoof growth rate, renewal, and hoof angle were recorded in foals (n=80) and weanlings/yearlings (n=12) and the hoof wall structure of histological samples of fetuses and paediatric foals (n=15) was determined.
