Scratches, also called mud fever or pastern dermatitis, is a condition that shows up as inflammation, scabbing, and crusting on a horseโs lower legs. It is often linked to bacteria (such as Dermatophilus congolensis or Staphylococcus), fungi, and sometimes viruses or mites (UC Davis Center for Equine Health). While environment and hygiene are major factors, an important question remains: why do some horses tolerate even the harshest conditions while others develop problems so quickly?
From an osteopathic perspective, this comes down to more than just the outside influences we see, touch, and smell. Yes, we notice the scabs and inflammation outwardly, but a whole other environment exists inside the horseโthe โinternal environment.โ This internal state is just as important, if not more (Animal Osteopathy Worldwide).
The body constantly works to maintain homeostasisโbalance within all systems. When balance is present, the horse can withstand external stressors. When the body is already struggling to maintain that balance, outward symptoms like pastern dermatitis appear. It isnโt just โbad luckโโitโs a sign that the body cannot properly manage additional challenges (The Whole Horse โ Equine Osteopathy).
For example:
A horse on a diet high in sugars and synthetics may develop circulatory issues. Good blood flow is essential to keep tissues healthy. If circulation is hinderedโlike stepping on a hoseโthe tissues donโt receive proper nutrients, leaving them vulnerable to bacterial or fungal infection. Over time, those areas become โweak linksโ where problems like scratches can arise ([Geor & Harris, Equine Applied and Clinical Nutrition, 2013]).
As osteopaths, we know no imbalance exists in isolation. The whole body is connected, and if one area is compromised, others are affected. When we assess a horse, we look for whatโs not moving as it shouldโwhether in musculoskeletal structures, visceral organs, or fascial tissues ([Barral & Croibier, Osteopathic Approach to Animals, 2009]).
Common contributors to pastern dermatitis include (but are not limited to):
โข Poor diet and nutrition imbalances ([Geor & Harris, 2013])
โข Hoof imbalances ([Clayton & Hood, Equine Veterinary Journal, 1987])
โข Thoracic inlet restrictions ([Barral & Croibier, 2009])
โข Dental imbalances (involving the entire stomatognathic system) ([Staszyk & Gasse, Equine Veterinary Education, 2004])
โข Cranial, sacral, or visceral restrictions ([Barral & Croibier, 2009])
By addressing these underlying imbalances and supporting the bodyโs natural ability to heal, we can often resolve not only the skin symptoms but also the internal struggles that allowed them to develop in the first place.
