Caudal failure refers to a regression in the integrity, structure, and function of the back of the foot. Not always, but typically this is associated with low or negative palmar (front feet) or plantar (hind feet) angles. NPA = negative palmar/plantar angle. In my practice, I consider low angles zero to 2-3 degrees, while anything negative obviously is below zero degrees. Ideal palmar/plantar angles range from 4-8 degrees, but this depends on the horse. I have some horses who prefer to be on the lower end of this range, while others appreciate to be at the higher end.
Thrush is an anaerobic bacterial infection that can cause an array of issues. Often the frog is the primary victim, though the central sulcus can be a forgotten area of attack. The central sulcus is the top/center of the widest part of the frog (at the back of the foot). Central sulcus thrush can create a “butt crack” appearance. This infection can be very painful for the horse and can even alter their landing to avoid impact on infected tissue. Landing may switch from the ideal heel first landing, to flat or toe first landings (which comes with its own myriad of biomechanical issues).
As a horse owner, it's essential to prioritize your equine companion's hoof health. Regular hoof care is crucial for maintaining the overall well-being and performance of your horse. Neglecting hoof care can lead to a range of problems, from mild discomfort to severe lameness and even long-term damage.
