Bruised Sole or Abscess issues?
Proper hoof trimming is vital to preventing injury causing lameness in horses. Keeping horses’ bars aligned and healthy are key to prevent a “stacked sole,” or worse, a bruised sole or abscess.
Bars appear as white lines along the frog and are made up of lamina. Think of the bars like plastic straws. If you push down on the straw from the top, it stays strong and holds its form. If a straw gets too long, it will likely bend with pressure applied and become weak.
Symptoms of Unhealthy Bars
When horses show signs of lameness, it’s important that a hoof care professional examines the sole to make sure the bars are aligned and visible. If either of those factors is missing, then the bars are not healthy and the hoof is not being trimmed or maintained properly. The bars essentially begin growing forward and down toward the ground and changing directions. This causes the bars to grow into the soft tissue of the sole if left untrimmed. When the overgrown bars begin to apply pressure on the soft or horney part of the sole, it causes lameness and discomfort.
Unhealthy Hoof Bars
Symptoms of unhealthy bars can be addressed so the condition does not get worse.
Stacked Sole: When bars are too long, it causes a horse to distribute its weight unevenly. Thus, the heels can become bent and the sole looks like it has a stacked effect. Eventually, this causes sole bruising as the long bars bend into the soft tissue of the sole. In rare cases, the bars are not visible at all and can minimize blood circulation from the pressure it applies on the soft tissue of the hoof cavity.
Pinched Heels: If the heels are too far forward, the heels become pinched and contracted, causing the horse to bear all of its weight on its toes. If this is not treated in a timely manner, it can cause injury.
Farriers may have different approaches when it comes to managing the bars. Some may suggest removing them and others might not want to trim them at all.
For optimal hoof care, there is a happy medium. Bars should be trimmed such that the white lines (lamina) of the sole are always visible. In addition to being visible, it’s important that there is very little bend or deviation.
A horse needs to distribute its weight evenly so that it can land on its feet without putting stress on the toes and pinching the heels. When bars are crooked and too long, it becomes uncomfortable and prevents a horse from standing evenly. A farrier should be able to look at the bars to determine if they are too long, then decide whether to trim or apply pour-in pad products as needed.
If the bars are so stacked or buried that you cannot visibly see them, soft pour-in pad products can help to keep moisture in the hoof so that the bars will loosen, making them more noticeable and easier to find for trimming.
Vettec Equi-Pak is soft enough that it will not irritate the sensitive area if the horse is lame. Equi-Pak is fast-setting, soft pad material that bonds directly to the sole and frog, and improves the depth of the sole. Applying pour-in pads can be used as a tool to loosen up the sole, making bars visible and the hoof more comfortable to stand on.
The feet are a major aspect of a horse’s overall health. If the bars are not maintained properly and weight is not distributed evenly, it can cause injury and lameness, affecting a horse’s ability to do many daily activities. With consistent and proper trimming regimens, a horse will have healthy bars, be able to stand evenly and bear weight comfortably.
Talk with your farrier or veterinarian about your horse’s bars, and how pour-in pad materials can be a helpful tool for trimming and examining the hoof cavity.
