Veterinary practice in relation to horses encompasses the medical care, management, and treatment of equine species. This field involves various aspects of equine health, including preventive care, diagnosis, and treatment of diseases, surgical interventions, and emergency care. Equine veterinarians employ a range of diagnostic tools and techniques such as physical examinations, imaging, and laboratory tests to assess and monitor horse health. In addition to addressing physical ailments, veterinary practice also includes nutritional management, reproductive health, and performance-related issues. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, advancements, and outcomes in veterinary practices specific to equine health.
Robinson RC.Most practitioners will have experienced the
frustration encountered in the treatment of sprains
of the flexor tendons and suspensory ligaments
of racehorses. After apparent recovery, the
damaged structure will often break down again
when the horse returns to hard training. Milne
(1960), Reed (1962), Jubb and Kennedy (1963)
and Hickman (1964) have written detailed ac-
counts of the pathology of tendon injuries and the
mechanism of repair of tendon tissue. These
writers substantiate that when a tendon is
sprained, there is a tearing or rupture of some of
the tendon fibres, varying i...
Christley RM, Rose RJ, Hodgson DR, Reid SW, Evans S, Bailey C, Hodgson JL.This study evaluated a questionnaire investigating the attitudes and behaviours of veterinarians regarding the cause, diagnosis and treatment of lower respiratory-tract disease in racehorses. The questionnaire was sent to all non-student members (648) of the Australian Equine Veterinary Association: two mailings and a single telephone contact (each separated by four weeks). Subsequent phases were only administered to those who had not responded to earlier phases. In total, 467 (72.1%) of the 648 mailed questionnaires were returned. Of these, 354 were usable. The remaining 113 respondents gave ...
Dwyer AE.Equine practitioners examine patient eyes on a daily basis. Indications range from inspection of normal anatomy to treatment of traumatized eyes to workups of sight threatening inflammatory or neoplastic ocular conditions. Assessment of equine eyes requires practitioners to take time to create a good "exam room" in the field and administer appropriate restraint, sedation and/or regional anesthesia to facilitate thorough examination. Accurate diagnosis and treatment of equine eye problems requires skill in ocular surface staining and cytology, and basic proficiency in standing surgery. Expertis...
Breuer D.In spite of regular vaccinations against equine influenza we are still observing a high rate of patients with respiratory problems in the equine practice. In our practice in Munich Riem, into which a horse clinic has been integrated, 4000 horses have been treated in 1985 alone. 874 of these showed some form of respiratory disease (= 22%). All of the 4000 horses have only been treated curatively, i.e. preventive forms of treatment such as vaccinations, deworming and examinations for insurance companies and prior to selling have not been taken into account. From 1983 until today in our clinic 25...
Attenburrow DP, Bowring CS, Vennart W.The detection of radionuclide activity in the living equine skeleton, using bone seeking radiopharmaceuticals and a hand-held radiation detector, is reported. Pathological changes in bone can be detected and subsequent development monitored. The availability and use of this diagnostic technique in equine practice is discussed.
Galloway SS, Easley J.This article discusses the significant features and use of digital cameras, intraoral cameras, and oral endoscopes in equine dental practice. Although system features believed to be important have been listed, specific system recommendations have been omitted, since each veterinarian must individually determine the best system to meet practice clinical needs and budget. Veterinarians are encouraged to thoroughly research not only the camera/endoscope purchase but also the capabilities of the entire system, the compatibility of the system with different computer software programs, the reputatio...
Meier HP.The genetic predisposition to navicular disease is proven nowadays, but otherwise, etiology and pathogenesis are still unclear. Causal therapy isn't possible and because of the poor prognosis, neurectomy is still of bearing. This operation was performed already 200 years ago, but in the middle of the last century, critical voices have been raised in regard to the surgical procedure and its indication both for medical reasons and breeding. Clear instructions for exclusion of diseased animals from breeding are also older than one hundred years. These facts call for ethic considerations which con...
O'Grady SE, Dryden VC.A club foot or flexural deformity may affect a horse at any stage of life from neonate through adulthood. The emphasis of this article is on defining and recommending the appropriate farriery for flexural deformities involving the deep digital flexor tendon and the distal interphalangeal joint. Clinical management of the flexural deformity is influenced by the severity, duration, and etiology of the club foot as well as the degree and source of lameness. Also discussed is the management of mismatched hoof angles, which remains a controversial subject for both farrier and veterinarian.
Iff I, Mosing M, Lechner T, Moens Y.To determine the usefulness of an acoustic device to confirm correct placement of extradural needles in horses. Methods: Prospective experimental study. Methods: Twelve adult healthy horses weighing between 434 and 640 kg. Methods: Horses were sedated, placed in stocks and subjected to caudal extradural anaesthesia using lidocaine 2%. For extradural puncture an 18 gauge Tuohy needle connected to an acoustic device via an electronic pressure transducer was used. This device allowed recording of the extradural pressure profile and the transformation of pressure changes into an audible signal. Ex...
Nunamaker DM, Nash RA.To report development, configuration, application, and results of a tapered-sleeve transcortical pin external skeletal fixation device (TSP ESFD) for use on fractures of the distal aspect of the equine limb. Methods: Optimization analysis of a TSP ESFD was carried out with mechanical testing and review of clinical case outcomes. Methods: Cadaveric adult third metacarpal bones (MC3) for mechanical testing; horses (n=7) with severely comminuted proximal (6; P1) or second (1) phalanx fractures. Methods: Mechanical testing of methods for attachment of TSP to the sidebars were tested as well as opt...
Corveleyn S, Deprez P, Van der Weken G, Baeyens W, Remon JP.Six healthy mares ranging in age from 6 to 12 years and weighing from 415 to 540 kg were used to determine the rectal bioavailability of ketoprofen. For the rectal administration, three different formulations, each containing 1 g of ketoprofen, were administered in a fatty and a hydrophilic suppository base and as a liquid suspension. An average elimination half-life of 1.3 h (+/-1.2) was found. The average value for the total plasma clearance (ClT) was 131.9mL/ min.kg (range 95-183.5). The volume of distribution Vd(area) was 255 mL/kg and the mean residence time (MRT) value was 0.47 h. After ...
Webbon PM.The radiography of horses on behalf of a purchaser has become an inevitable part of a veterinarian's work. Radiography should, in theory, pose no more problems than a general clinical examination. In practice, difficulties arise when insufficient or inadequate films are taken or the films are misinterpreted. Radiographs of a diagnostic quality need to be taken and interpreted by a veterinarian who is reasonably well versed in radiological interpretation. Occasionally a lesion will be overlooked or misinterpreted and the radiographs will be retained so that the veterinarian's judgement can be c...
James OA, Elce Y, Cillán-Garcia E, Reardon RJM. The aim of this study was to determine whether a clamped drill guide can be used effectively to drill across equine distal third metacarpals and metatarsals and to compare accuracy and speed of a drilling with a hand-held drill guide. Methods: Eighty equine cadaver limbs were divided between four surgeons with varying experience. The limbs were randomly allocated to clamped or hand-held drill guides and placed in a stand in an upright/standing position on a metal table. Drilling times from cis- to trans cortices were measured. Post-drilling computed tomography images were used to assess ...
Wyant LA.The Internet is a fast-growing technology that allows information (text as well as images) to be shared across the world in an instant. As computer systems, software, and Internet services become less expensive options, the world becomes more experienced and comfortable with these technologies. In the foreseeable future, equine veterinarians are likely to be better educated about diseases and treatments, better connected with specialists for consultations on difficult cases, able to respond to client communications more efficiently, able to accurately educate clients, and able to communicate w...
Dart AJ, Strong M, Rose RJ, Hodgson DR.To evaluate the clinical, haematological, and serum biochemical effects of two large doses of recombinant equine growth hormone. Methods: Duplicated Latin square. Methods: Three Thoroughbred and three Standardbred mares aged between 12 and 17 years. Methods: Two horses were randomly assigned into one of three groups. On each of three successive days, each horse pair received one of two dosages of growth hormone or a saline placebo so that by the end of the experiment all three horse pairs had received both dosages and the saline placebo. Dose rates selected were 50 micrograms/kg, and 100 micro...
Natalini CC, Alves SD, Guedes AG, Polydoro AS, Brondani JT, Bopp S.To evaluate the analgesic, physiologic, and behavioral effects of the epidural administration of tiletamine/zolazepam in horses. Methods: Prospective, double-blind, randomized experimental study. Methods: Five adult, healthy horses aged 10-16 years and weighing (mean +/- SD) 400 +/- 98 kg. Methods: The horses were sedated with 1.0 mg kg(-1) intravenous (IV) xylazine, and an epidural catheter was placed into the first intercoccygeal intervertebral space. After a 48-hour resting period, epidural tiletamine/zolazepam, 0.5 mg kg(-1) (treatment I) or 1.0 mg kg(-1) (treatment II), diluted up to 5 mL...
Smit LA, Wouters IM, Heederik D, Douwes J.Endotoxins are cell-wall components of Gram-negative bacteria that are commonly present in plants and plant products and in faecal matter. This review presents an overview of endotoxin exposure levels, associated health effects, and relevance regarding veterinary practice. Exposure to airborne endotoxin is especially high in the agricultural sector and among veterinarians, and in particular among those working with horses or farm animals. Inhalation of endotoxins may cause acute airway inflammation and respiratory symptoms that can lead to (non-allergic) asthma and chronic obstructive pulmonar...
Boorman S, DeGraves F, Schumacher J, Hanson RR, Boone LH.To compare a 2% lidocaine solution containing 5 μg/ml (1:200 000) epinephrine with 2% mepivacaine for reducing lameness in horses after use in proximal nerve blocks. Methods: Experimental randomized crossover. Methods: Six adult horses with naturally occurring forelimb lameness. Methods: Horses were evaluated using an inertial gait sensor system. Lameness was measured as a vector sum (VS). Following baseline lameness examination, median and ulnar nerve blocks were performed with lidocaine/epinephrine (0.5 mg epinephrine added to 50 ml of 2% lidocaine immediately prior to administration)...
Oosterlaan-Mayer B, Back W, Sloet van Oldruitenborgh-Oosterbaan MM.All horses and ponies with laminitis treated at the Department of Equine Sciences, Faculty of Veterinary Medicine, Utrecht University, between 1995 and 1998 were analysed retrospectively (n = 152). Based on the results of this study and on the world-wide knowledge on laminitis a standardised treatment protocol was adopted in 1999. Fifty-eight patients have been treated for laminitis between 1999 and 2001 following the treatment protocol. Compared to our hospital-population (orthopaedic patients), mares and ponies are at higher risk developing laminitis, but the prognosis does not differ betwee...
de Vries PJ, Zandee AR.As part of the veterinary surveillance of horse breeding management, the veterinarian is increasingly often requested to predict ovulation and to give a breeding or insemination advice accordingly. The result of a teasing procedure is indispensable for this advice. A suggestion is made for the quantification of oestrus signs. Oestrus symptoms are classified into four categories. In addition, various factors are mentioned, which affect the result of a teasing procedure.
Fubini SL, Cummings JF, Todhunter RJ.Painful neuroma formation after palmar digital neurectomy in the horse is common. Experimentally, injection of doxorubicin (Adriamycin) into the proximal transected nerve stump has been shown to prevent axon sprouting and neuroma formation for up to 5 months. This procedure was used in 28 horses with navicular disease, preexisting painful neuroma, or wing fractures of the distal phalanx. At 1 month, 16 horses had incisional complications. At 1 year, 15 horses were sound. Eight horses were lame, although three were improved. Three horses required a second surgical procedure, two of which became...
Al-Dissi A.A wide variety of toxins cause diseases in the horse and are investigated routinely by veterinarians and veterinary pathologists to identify the cause of illness and death. A complete investigation involves performing a thorough necropsy and requires macroscopic and microscopic examination of lesions and a variety of laboratory testing to obtain an accurate diagnosis. The identification of gross lesions by equine practitioners is often the first step in formulating a diagnostic plan. This article provides a description of selected common toxins producing detectable gross lesions in horses in N...
Maher M, Kuebelbeck L.Nonhealing wounds present a common challenge to the equine practitioner. An underlying source of inflammation and infection is almost always present and needs to be resolved for healing to proceed. Wound débridement is the mainstay for this resolution. In addition, wound closure, wound dressings, and skin grafts can be used to achieve successful wound healing.
Lacitignola L, De Luca P, Imperante A, Tommasa SD, Crovace A.The aim of this study was to evaluate the use of a single-portal endoscopic desmotomy of the PAL with the use of Arthrex - Centerline™. Ten horse distal front limbs from horses free of PAL disease were prepared for tenoscopy of the digital flexor tendon sheath (DFTS). A dual-port endoscopic desmotomy with a hook knife was performed in 5 specimens (Group A) and single port Arthrex-Centerline™ Desmotomy was performed in another 5 specimens (Group B). The performing time, judgments of the surgeon, number of blade passages, and gross anatomy were evaluated. The performing time and surgeon judg...
Klug E, Brinkhoff D, Flüge A, Scherbarth R, Essich G, Kienzler M.Practical experiences of the phantom method for collection of genital secretions from stallions are reported. Taking a phantom used in the Richard-Götze-Haus Tierärztliche Hochschule Hannover as a prototype two further models slightly modified have been constructed, baring a flat hollow in the right side of the caudal phantom body for manual inserting of the Artificial Vagina. These three models fulfill four important conditions for routine use: (1) sufficient sexual attractivity for the stallions; 80-85% successful collections of presecretions out of a total of 1050 using the dummy and 70% ...
Spurlock GH.This article deals with the diagnosis and treatment of tendon lacerations. Tendon healing, with its implications relative to treatment, is discussed. The various pros and cons of suturing severed tendons are addressed as well as methods of immobilizing the injured limb. The need for prompt diagnosis and aggressive treatment of tendon sheath injuries is also discussed.
Viljoen A, Saulez MN, Carstens A, Gummow B.Clinical use of diagnostic ultrasound at point-of-care or emergency situations, although common, has not been well documented in veterinary medicine. Medical records of after-hour emergency equine admissions during a 10-year period were reviewed and horses that received ultrasound scans were identified. Data sheets for each ultrasound scan performed during emergency clinical evaluation were collected and reviewed. Data extracted included anatomical region imaged, body system affected, documented ultrasonographic diagnosis and final diagnosis. Six hundred and nine records were available of whic...
Puschner B, Galey FD.Poisoning in the horse can present a highly complex case. The practitioner, owner, toxicologist, and pathologist play important roles, and all contribute information that may be important to the case. Once all the information is available, all the evidence is collected (historical, clinical, pathologic, and analytic), and proper sampling of specimens has occurred, a complete summary of the findings can be provided to the client. Based on identification of a potential toxic source and, ultimately, the diagnosis, specific treatment of affected animals and prevention of additional cases can be in...
Koterba AM, Drummond WH.Provision of adequate nutritional support to the sick neonatal foal is a vital part of intensive care; frequently, however, it is very difficult to accomplish. In this article, current recommendations concerning both enteral and parenteral nutrition are discussed.
Teigland MB.The role of the veterinarian at auction sales begins long before the consignment is assembled. A number of veterinarians are called upon by sales companies to evaluate the candidates before acceptance into the consignment. At sales time, the number of veterinarians involved grows to large numbers as the prospective buyers employ them to evaluate the animals to suit their individual needs. Professional ethics must be considered at all times when evaluating animals before auction. The findings must be kept confidential. The consignor allows veterinarians to examine his or her animals with the un...
Steinfeld Y, Akian R, Rovitsky A, Puchkov N, Keren Y.In recent years, treatment for Achilles tendon rupture (ATR) went through radical changes: from the conservative non-weight bearing approach to a functional protocol. This functional protocol allows complete weight bearing after only 2 weeks by placing the foot in a plastic boot in tapered down equines and using interchangeable wedges under the heel. This change of approach has dramatically lowered the rate of re-rupture. Objective: To describe our preliminary results with this functional protocol and to assess outcome measures in the functional conservative treatment. Methods: The study compr...
