This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, outcomes, and advancements in veterinary procedures for horses, providing insights into their application and efficacy in equine medicine.
Acupuncture Points of the Horse’s Distal Thoracic Limb: A Neuroanatomic Approach to the Transposition of Traditional Points. Veterinary acupuncture charts were developed based on the concept of transpositional points whereby human acupuncture maps were adapted to animal anatomy. Transpositional acupuncture points have traditionally been placed in specific locations around the horse's coronet and distal limb believed to be the closest approximation to the human distal limb points. Because the horse has a single digit and lacks several structures analogous to the human hand and foot, precisely transposing all of the human digital points is not anatomically possible. To date there is no published research on the effect...
Detection of peginesatide in equine serum using liquid chromatography-tandem mass spectrometry for doping control purposes. Erythropoietin (EPO) and its recombinant analogues are suspected to be illicitly administered to horses for performance enhancing purposes and, consequently, prohibited in equine sports. Recently, a new erythropoiesis-stimulating agent, peginesatide (Omontys, formerly referred to as Hematide), belonging to the upcoming class of EPO-mimetic peptides, received approval for the treatment of anaemia in humans with chronic kidney disease on dialysis. As the pegylated dimeric peptide of approximately 45 kDa without sequence homology to EPO is not detectable by conventional EPO detection assays, spec...
Modified Kuhnt-Szymanowski surgical procedure for secondary cicatricial ectropion in a horse. A 1-year-old Dutch Warmblood gelding was presented to the University of Florida's Large Animal Hospital (UF-LAH) for correction of ectropion of the right lower eyelid. The ectropion was the result of a lower eyelid laceration. A primary repair was performed by the referring veterinarian; however, the horse prematurely removed the sutures and the wound healed with inversion of the eyelid margin. Surgical correction of the entropion, with removal of tissue from the lower eyelid, resulted in cicatricial ectropion. During the initial evaluation at UF-LAH, a corneal ulcer was noted in the right eye...
Content validity of the Rodeo-SCAT. The purpose of this study was to establish the content validity of the Rodeo SCAT for the sport of rodeo and bull riding. The study design was comprised of expert consensus and content validation. A modified Ebel procedure was employed to content validate the rodeo SCAT. Content validation using this method includes experts agreeing on the importance of each item that comprises the rodeo SCAT. This 3-stage process involved: 1) face validation by a local committee: 2) initial expert consensus measurement via distance; and 3) a face-to-face discussion for items that did not originally achieve 80...
Intestinal ischemia-reperfusion injury in horses: pathogenesis and therapeutics. This article discusses the potential role of oxidative injury to the intestinal tract of horses and the therapeutic approaches that have been investigated to decrease cellular damage secondary to ischemia-reperfusion (IR) injury. Equine colic is a major concern for horse owners and veterinary practitioners. Strangulating and obstructive lesions of the small and large intestines commonly require intervention in patients via exploratory celiotomy. However, the application of information from experimentally induced IR injury in horses to clinical cases of naturally occurring equine colic is not c...
Efficacy of concurrent epidural administration of neostigmine and lidocaine for perineal analgesia in geldings. To evaluate perineal analgesic effects of 3 doses of neostigmine coadministered epidurally with lidocaine to geldings. Methods: 6 healthy geldings. Methods: A few days before each treatment, a catheter was inserted between the first and second coccygeal vertebrae via the caudal approach in each gelding; the catheter tip was threaded approximately 10 cm cranial into the midsacral region. Each horse received 4 epidural treatments: 2% lidocaine (0.2 mg/kg) alone and 3 doses of neostigmine (0.5, 1, or 2 μg/kg) coadministered with that same dose of lidocaine. Horses were restrained in stocks in a ...
Liver lobe torsion in six horses. 6 horses were determined to have torsion of a liver lobe at 4 referral institutions over a 21-year period. Results: Clinical findings were nonspecific but often included signs of marked inflammation. Two of the 6 horses were examined because of colic, and 2 were assessed because of peritonitis that failed to respond to treatment; the remaining 2 horses were examined because of nonspecific clinical signs that included inappetence, lethargy, and weight loss. The results of laboratory tests were widely variable, and values for liver enzyme activities were typically within reference limits or only...
The isolated perfused equine distal limb as an ex vivo model for pharmacokinetic studies. Even though intra-articular injections play an important role in the treatment of joint-related lameness in horses, little is known about pharmacokinetic properties of substances used. Therefore, an ex vivo model for pharmacokinetic studies was developed using distal forelimbs of slaughtered horses. The extremity was perfused with gassed Tyrode solution for up to 8 h. Tissue viability was confirmed by measurements of glucose consumption, lactate production, and lactate dehydrogenase activity in the perfusate. Standard criteria for tissue viability had been determined in preliminary experiments...
The effect of varying echo time using T2-weighted FSE sequences on the magic angle effect in the collateral ligaments of the distal interphalangeal joint in horses. Eight skeletally mature equine cadaver distal forelimbs were imaged using T2-weighted fast spin echo (FSE) sequences in a 1.0 T horizontal bore magnet. Each limb was parallel to the main magnetic field and with 16° angulation of the limb relative to the main magnetic field, which places one of the collateral ligaments of the distal interphalangeal joint at or near the magic angle. Each limb was imaged using an echo time (TE) of 80, 100, 120, and 140 ms. Reversal of the magic angle effect was achieved at echo time of 140 ms. However, given the alterations in tissue contrast and subjective decr...
Readability of branding symbols in horses and histomorphological alterations at the branding site. Identification of horses has traditionally been facilitated by hot iron branding, but the extent by which branding symbols and numbers can be identified has not been investigated. The local pathological changes induced by branding are also unknown. This study analysed the readability of branding symbols and histomorphological alterations at the branding sites. A total of 248 horses in an equestrian championship were available for identification of symbols and numbers. A further 28 horses, euthanased for other reasons, provided histological examination of the branding site. All except one horse...
Anesthesia of the geriatric equine. Advancements in veterinary medicine have resulted in an increased number of geriatric horses being presented for medical or surgical procedures that require general anesthesia. Due to the physiological changes associated with aging and the likelihood of concurrent disease conditions, the geriatric equine is at an increased risk during anesthesia. The main physiological changes associated with aging, and their impact on anesthesia, are discussed in this review.
Development of a quantitative multivariable radiographic method to evaluate anatomic changes associated with laminitis in the forefeet of donkeys. To establish and validate an objective method of radiographic diagnosis of anatomic changes in laminitic forefeet of donkeys on the basis of data from a comprehensive series of radiographic measurements. Methods: 85 donkeys with and 85 without forelimb laminitis for baseline data determination; a cohort of 44 donkeys with and 18 without forelimb laminitis was used for validation analyses. Methods: For each donkey, lateromedial radiographic views of 1 weight-bearing forelimb were obtained; images from 11 laminitic and 2 nonlaminitic donkeys were excluded (motion artifact) from baseline data det...
Equine distal limb wounds: new and emerging treatments. Distal limb wounds occur commonly in horses, and treatment can be frustrating for owners and veterinarians. Caring for these wounds is often very expensive, labor intensive, and prolonged. Many commercial products and clinical techniques have been developed to help treat these wounds. Healing of these wounds depends on many factors. With proper wound evaluation and treatment, affected horses can return to function sooner than in the past.
Intussusception in horses. Intussusception is thought to be associated with abnormal motility in the intestinal tract. The clinical signs vary depending on the associated intestinal damage. Therefore, intussusception should be included in the differential diagnosis for any horse with acute or chronic colic. A diagnosis may be made by ultrasonography or rectal palpation, but exploratory laparotomy is the predominant method. Treatment varies according to the location of the intussusception, but all treatments involve surgical intervention. The prognosis for intussusception can be good if the condition is diagnosed and tre...
Morphology of distal border synovial invaginations of the equine distal sesamoid bone: comparison between computed tomography and a hoof-specific radiographic projection. To compare the difference and agreement of the morphology of distal border synovial invaginations on a dorsoproximal-palmarodistal oblique (DPr-PaDiO) projection with hoof-specific angle versus computed tomography. Methods: Computed tomography (CT) images and a DPr-PaDiO radiographic projection with hoof-specific angle were obtained on 50 cadaveric forefeet from 25 Warmblood horses. Computed tomography was assumed to be the gold standard. The number, shape and depth of penetration of distal border synovial invaginations into the distal sesamoid bone were evaluated with both methods, and the co...
Resolution of sustained narrow complex ventricular tachycardia and tachycardia-induced cardiomyopathy in a Quarter Horse following quinidine therapy. Sustained narrow-QRS tachycardia of three months duration and left ventricular systolic dysfunction were identified in a fifteen-year-old Quarter Horse. No underlying cause for the tachyarrhythmia was found and no predisposing structural cardiac lesions were evident by echocardiography. Intravenous diltiazem and lidocaine were administered without achieving successful conversion of the arrhythmia. Oral quinidine therapy converted the tachyarrhythmia to sinus rhythm. Ventricular systolic dysfunction and chamber dilatation subsequently resolved. As with other species, echocardiographic features ...

Methods: All horses underwent the modified LTFP. Modifications of the surgical procedure consisted in the use of 3 metallic stents called Suture Button(TM) through which the sutures are threaded and in ...
Indwelling cephalic or saphenous vein catheter use for regional limb perfusion in 44 horses with synovial injury involving the distal aspect of the limb. To describe indwelling cephalic or saphenous vein catheter use for intravenous regional limb perfusion (ID-IV-RLP) to treat horses with synovial injury (contamination/infection) of the distal aspect of the limb. Methods: Retrospective case series. Methods: Horses (n = 44; 45 limbs) treated with proximal ID-IV-RLP. Methods: Horses had ID-IV-RLP using a cephalic (21 limbs) or saphenous (24 limbs) vein. Amikacin was the most frequently used antibiotic. Number of perfusions ranged from 3 to 21 (median 7). A cast was applied to 14 injured limbs (1 tube cast, 1 full-limb cast, 2 foot casts, and 10 h...
Equine imaging: the framework for applying therapeutic farriery. Radiographic evaluation of a horse's foot gives tremendous insight into the relationship between the structures within the foot and between the foot and distal limb. The information gained from a radiographic study is highly dependent on the quality of the radiographs. A systematic approach should be taken when planning a radiographic study of the foot. Taking the time to examine the foot and prepare it properly will avoid the need, risk, and expense of repeating images and will improve the quality and therefore the interpretation of your radiographic images. When evaluating the foot for podia...

Radiography was performed every week until the study endpoint at 12 weeks. After euthanasia, bo...
The proximal aspect of the suspensory ligament in the horse: How precise are ultrasonographic measurements? To evaluate intra- and interobserver variability in ultrasonographic measurements of the proximal aspect of the suspensory ligament (PSL) in the horse. Objective: A minimum difference of ≥20% is required to differentiate reliably between physiological and pathological alterations related to dimensions. Methods: Two operators examined the PSL in all 4 limbs of 14 horses twice using different techniques and different probes with and without standoff pads. Measurements were taken from the longitudinal and transverse images. Inter- and intraoperator variability was evaluated using agreement indi...
Periodontal biomechanics: finite element simulations of closing stroke and power stroke in equine cheek teeth. In equine dentistry periodontal diseases, especially periapical inflammation, are frequently occurring problems. Anachoresis is believed to be the most common cause for the development of such disorders. Nevertheless, there is still no substantiated explanation why settlement of pathogen microorganisms occurs in equine periodontal tissues. It is expected that excessive strains and stresses occurring in the periodontal ligament (PDL) during the horse's chewing cycle might be a predisposing factor. In this study this assumption was examined by finite element (FE) analyses on virtual 3-D models o...
