  • Subjective vs. Objective Lameness Identification Methods

    Lameness evaluations can be extremely subjective. When examining a horse with a mild lameness, in particular, veterinarians often don’t agree on a diagnosis—some are prone to seeing a more sound horse, others a more lame one. To overcome such disparities, practitioners have turned to objective methods such as force plates and inertial sensor s...

  • Which Cryotherapy Method Works Best for Cooling Hooves?

    Continuous cooling of the hoof and its blood supply (cryotherapy) has been shown to prevent laminitis in at-risk horses. But which cooling method is most effective? Australian researchers recently evaluated several commonly used hoof-cooling methods to see how they compared.

  • Researchers Evaluate Equine Hematology Parameters

    Italian researchers believe that a wide number of “healthy” variables—such as breed and geographic location—might impact horses' blood test results. And with the current textbook reference hematology values being based on the Thoroughbred horse in the United Kingdom, the team believes it might be time to develop new reference v...

  • 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...

  • Airflow's Impact on Thermographic Readings of Horse Legs

    Considering thermography to evaluate a horse's legs? Better move that patient inside and shut the doors. Austrian researchers recently learned that wind and air drafts can affect themographic readings of horses’ front legs—very quickly, in fact—potentially leading to false positive or negative results.

  • 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...

  • Limb Positioning for Assessing Joints via X Ray (AAEP 2012)

    Lower limb radiographs can help practitioners uncover valuable information about bones, joints, and joint balance in equine athletes, but Colorado State University (CSU) researchers have determined the usefulness and accuracy of this information depends largely on how the horse stands during X ray capture.

  • MRI to Evaluate Suspensory, Sesamoid Injuries (AAEP 2012)

    Since its inception in the 1930s, the inaugural patent in 1974, and the successful construction of the world’s first whole-body scanner by 1977, magnetic resonance imaging (MRI) has become an indomitable tool in both human and equine medicine. Today, equine practitioners use MRI extensively to help diagnose even the most subtle lameness causes.

  • Ultrasound for Arytenoid Chondritis Diagnosis? (AAEP 2012)

    Veterinarians often choose upper airway endoscopy when working to diagnose equine arytenoid chondritis--an uncommon but problematic respiratory condition--but in some cases a definitive diagnosis lies out of reach. Ultrasonography could offer a valuable adjunct tool for diagnosing this respiratory condition, however, especially in cases lacking a definiti...

  • Hoof Angles' Impact on Lameness Examined

    Get out your protractors: New research shows that the various angles of the outer and inner hoof are directly linked to various kinds of lameness, and knowing the angles could help determine which kind of lameness a horse has or is likely to get.

  • 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.

  • 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...

  • Using MRI and Scintigraphy to Diagnose Suspensory Injuries (AAEP 2012)

    The biblical saying, "two are better than one because they have a good return for their work," succinctly describes recommendations Natalie Zdimal, DVM, recently made regarding diagnostic imaging for suspensory-ligament-related injuries. Horses with such injuries generally have discomfort in the back the back of the fore- and hind-limbs near the...

  • 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...

  • 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...

  • Top Equine Surgery Studies of 2012 (AAEP 2012)

    Equine practitioners are undeniably busy individuals, making farm calls, caring for patients, and evaluating test results on a daily basis. To help veterinarians keep up to date on the most recent and relevant research, three veterinarians review the top studies in the fields of surgery, medicine, and reproduction at the annual American Association of Equ...

  • 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...

  • Study: Nanoparticles to Deliver Therapy for Heaves in Horses

    Scientists at Ludwig Maximilians University’s Department of Veterinary Medicine in Munich, Germany, are applying nanoscale molecule research in human allergy suppression to horses. In a recent study the team designed and administered a nanoparticleto deliver CpG-ODN (an immunostimulating DNA that has been shown to suppress allergies in humans) to ho...
