Study: Vets Disagree on Equine Neurologic Assessments

Is that horse lame, or is he exhibiting neurologic signs such as ataxia (incoordination)? For some horse owners, answering this question can be difficult. Recent study results suggest, however, that owners aren't the only ones that find it challenging to evaluate a possibly ataxic horse: Researchers determined that equine health experts have difficult...

Outcomes of Solar Surface Penetration Injuries Studied

Hoof sole penetration injuries are no small matter, though they might be nearly indiscernible to the eye and affect a small area. It’s more about what’s going on deep inside the hoof, where concealed damage to internal structures can be disastrous; the prognosis for horses injuring these structures to return to their prior athletic level is of...

Hoof Kinematics in Mild Lameness Diagnoses

You know that nagging feeling when your performance horse is just not quite right, yet you can’t pinpoint the problem zone? Here's some good news: By using hoof kinematics, researchers at the Gail Holmes Equine Orthopaedic Research Center at Colorado State University (CSU) are developing a technique to aid in the diagnosis of mild or subclinical...

Examining the Trot to Canter Transition Step by Step

Whether your horse takes several short, quick trot steps into the canter or jumps right into that rocking-horse gait, the moment when his legs change sequence probably seems fleeting. To a group of researchers from Michigan State University (MSU) though, that moment of change is of great interest.

Osteochondrosis Field Evaluation Protocol Developed

It's common knowledge that osteochondrosis—a developmental orthopedic disease that results from a disruption in the growth of articular cartilage located in specific joints—can cause problems for young horses, but how common is it? How are different breeds affected? Where are the most common lesion sites? And, of course, what’s the m...

Consider Trotting Speed when Diagnosing Subtle Lameness

Most horse owners are familiar with a typical lameness exam: The veterinarian observes the horse trotting briskly in a straight line, watching for signs of uneven movement. But if the patient is harboring a mild lameness, that brisk trot could be masking clinical signs, according to British researchers, whose recent study results indicate that evaluating ...

Therapeutic Ultrasound Settings for Horses Identified

Did you know that ultrasound can be used for more than just diagnosing tendon and ligament injuries in horses? Indeed, veterinarians can also use it therapeutically to treat soft tissue injuries, but what settings they should use and how long they should treat an injured horse has, until now, been a bit of a "guesstimation" game.

Ultrasonography to Diagnose Equine Lung Problems (AAEP 2012)

Ultrasound is a noninvasive tool veterinarians can use to diagnose myriad medical maladies, including those affecting either the lungs or the space around the lungs. Although practitioners perform thoracic ultrasound exams in referral settings routinely, they can also conduct these efficiently and effectively in an ambulatory setting, explained Virginia B...

Biomechanics and Hoof Problems, Treatment (AAEP 2012)

Lameness caused by foot problems is common in the horse, and it can significantly impact how well a horse can perform. Hoof bruising, heel soreness, hoof cracks all create discomfort that alter a horse’s gait and prevent him from giving his utmost to an athletic task. Nearly all equine foot diseases have their root in biomechanics, noted a Universit...

CT for Equine Limb Fracture Diagnosis? (AAEP 2012)

A fracture can put a horse's athletic future--sometimes even his life--on the line, and basing treatment on a complete and accurate diagnosis can make a major difference in the horse's recovery. A veterinarian in Belgium believes computed tomography (CT) offers a better option for imaging some lower limb fractures than radiography.

Hind-Limb Flexion Test Times Compared (AAEP 2012)

"A thorough lameness exam usually includes limb flexion tests to evaluate for gait changes when joints are stressed in a flexed position," remarked Amy Armentrout, DVM, MS, Dipl. ACVS, of Burleson Equine Hospital, in Texas. Holding the hind limb up for a protracted time can be tough on the practitioner's body, and horses aren't always co...

Navicular Bone Fragments' Effect on Lameness (AAEP 2012)

Although researchers have been studying the equine navicular bone for years, many mysteries still surround it. For instance, advanced imaging techniques give veterinarians a clearer picture than ever of irregularities or damage to the navicular bone, but it's not always evident what such pathologies mean for a horse's soundness. Elizabeth Yorke, D...

MRI to Identify Bone Changes in Racehorses (AAEP 2012)

Horses can't describe brewing musculoskeletal discomfort the way human athletes can, so trainers and veterinarians don't know which horses to put on the proverbial bench to prevent career- or even life-ending injuries. But an equine research team has been using MRI to detect bone changes that could indicate a horse is at risk for catastrophic fetl...

Decoding Small Intestine Problems with Ultrasound (AAEP 2012)

The sooner a veterinarian is able to determine whether a colicking horse requires surgery, the better the horse's chances of survival. Colic originating in the small intestine can be particularly tricky since it is not always easily felt on rectal palpation. Ultrasound examination, commonly used in general equine practices for diagnosing pregnancies a...

Handling Non-Weight Bearing Lameness in the Field (AAEP 2012)

One of the most common calls an ambulatory equine practitioner receives is that from a panicked owner whose horse becomes three-legged lame seemingly overnight, said Ryan Penno, DVM, a practitioner at The Equine Clinic at Oakencroft, in Ravana, N.Y. Whether the cause is a simple abscess or a complex fracture, Penno described how to manage acute-onset, non...

Hoof Radiographs' Role In Practical Farriery (AAEP 2012)

Radiographs are an often overlooked but indispensible tool for assessing a horse's feet and developing a hoof care plan that will maximize his soundness. At a recent in-depth seminar titled "The Foot from Every Angle," Randy Eggleston, DVM, of the University of Georgia's School of Veterinary Medicine, described how to optimize use of rad...

Identifying Laminitic Changes with MRI

Magnetic resonance imaging (MRI) might offer evidence of laminitic changes in a horse's hoof before the disease is otherwise identified. Equine radiologist and consultant Alexia McKnight, DVM, Dipl. ACVR, of McKnight Insight, in Chadds Ford, Pa., shared her anecdotal experience identifying laminitic changes via MRI during her presentation "Equine...

New In-Shoe Sensor Helping Horses Stay Sound

Laminitis is not only one of the leading causes of disability and death in horses, it's also an important cause of emotional and financial turmoil for owners. And for veterinarians, predicting which cases are likely to resolve or have the potential to become disastrous and how best to treat a given case remains a real challenge.

Digital Radiographs Beat Analog for Enterolith Detection

Veterinarians have known for many years that analog radiography is an efficient means of diagnosing enteroliths in adult horses, but computed, or digital, radiography has since replaced many analog machines. Researchers at the University of California, Davis (UC Davis) recently put the newer technology to the test and found it outperformed its predecessor...
