Case Study: Equine Stifle and SI Lameness

Leave a Comment / Equine Articles / By

Lameness in the horse can come in all different forms and severities.  One common source of lameness is the stifle but in many of these cases, it is also common to have problems either higher up or lower in the limb often tied in with conformational flaws or even trauma.  The saccroiliac region in the lower back or hip region is also a common source of discomfort, either alone or in conjunction with other problems.  The saccroiliac (S/I) joint is the area where the pelvic bone called the Ileum joins up to the Saccrum of the lower back.  The junction of the two is actually termed a joint, being held together by tough fibrous tissue, but still demonstrates some movement as the horse travels.  In a recent case presented for rehabilitation, we actually had apparent S/I problems in addition to chronic stifle lameness. When combined with unhealthy feet, severe thrush and sole pain, the case proved to be a real challenge.

Why is my horse always lame? Solving the Mystery

2 Comments / Equine Articles / By

One of the most common problems in the equine athlete and pleasure horse is recurring lameness, which can be equally frustrating for owner, rider and veterinarian.  At one moment, the issue may seem resolved, bringing relief, but then it may recur or maybe even a new problem develops. Being a veterinarian, horse owner and involved in the rehabiliation of horses, I understand the frustration but have come to realize that there is much to discover, learn and reveal when it comes to seeing the ‘entire’ horse in these situations. More often than not, the primary problem the horse is presented for is actually not the main issue, but in order to see the true problem, we need to step back and look at several factors. Despite us wanting to fix everything in one fail swoop, often the issue is more complex than we would like it to be.

Easy Keepers, Metabolic Syndrome and Lameness; What is the Connection?

Leave a Comment / Equine Articles / By

Easy keepers.  Most horse owners know what this term means almost instantaneously when they hear it.  In general terms, it refers to a horse that has a tendency to carry more weight and gain weight easily, often with just the sight of a green pasture.  Almost any horse can be an easy keeper, but there are certain breeds that are more prone including Quarter Horses, Pony breeds, draft breeds and even some warmbloods.  Many of these easy keepers progress to metabolic syndrome and even insulin resistance over time, each a stage of continued deterioration at a cellular level.  In many situations, these same horses tend to have concurrent lameness issues ranging from joint degeneration to tendon issues and laminitis, but also many also seemed more prone to allergies, respiratory problems and even eye issues.  What is the connection and why do many standard therapies fail to provide relief for this particular group of horses?

Inflammation and Impact on Health; Beyond Pain and Swelling

Leave a Comment / Equine Articles / By

When we think of inflammation, it is often in the form of pain and swelling.  Joint pain, stiffness, a wound or cut, sore back, sore throat or even an ear infection.  All of this is true and these conditions are associated with inflammation, but the overall concept goes much deeper, often being unrecognized clinically but all too closely tied with other health conditions.  It is an important concept to grasp, even on the most basic level, as with this understanding, we have opportunities to intervene which may give us more opportunities to manage and even prevent certain conditions.

Disease Prevention & Management; The 20,000 Mile View

Leave a Comment / Equine Articles / By

Everyone is looking for the ultimate cure or answer to whatever condition impacts their health or lifestyle, whether if that is for themselves, their pets or their horses.  Is there an answer out there? A solution to what ails you?  The answer is more complex than what you would like to hear, not necessarily a ‘yes’ or ‘no’, but more or less in between.

Immune Support and the Horse

Leave a Comment / Equine Articles / By

Does your horse have a healthy and strong immune system?  How do you know?  The most common problems we associate with a poorly functioning immune system are recurrent infections and even allergies, but what about other conditions?  Even in the case of infections, we most often attribute a poor immune response to more severe infections that may even result in hospitalization, but are there other clues or more subtle situations that may indicate that we have a problem?  The immune system is complex and involved in more bodily processes than one might just realize.

Nutrition Implications: Fact or Myth

Leave a Comment / Equine Articles / By

As a veterinarian, I have to confess that after almost 20 years of clinical practice, I failed many of my patients due to lack of knowledge about proper nutrition. Being a student in veterinary school, honestly, there was not much focus on nutrition.  In some courses, there was mention of various nutrients, but not much pressure to use the diet as a tool to aid in disease management and recovery.  The good news is that after all of those years, I did ‘wake up’ and realize the importance and today, my approaches are much different for myself, our pets and those horses that I have contact with on a daily basis.   It wasn’t always this way and I discover more each day, which can be exciting!

Horse and Dog Health; The Impact of Free Radicals and Oxidative Stress

Leave a Comment / Equine Articles / By

Free radicals are an important entity in chemistry and in health, having been researched for many years with connections to cellular changes that may impact overall health and aging.  A free radical is a molecule that has an unpaired electron in the outer shell, which creates instability and a high rate of reactivity with other molecules.  Free radicals are produced as a normal part of cellular respiration or energy production, but can also be generated as a consequence of environmental factors, stress, poor diet, food additives, medications and genetics.  In general, they can have huge negative impacts on overall health, performance and sustainability, but the good news is that with understanding, we also realize that there are things we can do to minimize the damage inflicted.

EPM and the Immune System; A clinical perspective

Leave a Comment / Equine Articles / By

Do you have a horse or know of one impacted by EPM? Equine Protozoal Myeloencephalitis (EPM) is unfortunately a common disease in the horse, impacting hundreds, if not thousands every year.  The outcomes for each case can vary dramatically, resulting in a huge expenditure for the owner and an uncertain future for the horse.  Give the huge variability in outcomes despite newer treatment options, one is left asking ‘why’ and what more can be done to aid in prevention and therapy to help increase the success rates. Maybe it is time to rethink our approach to these cases in order to maximize the outcome.
