Why is my horse’s hoof crack causing an abscess?

Overview
A hoof crack can sometimes allow dirt, moisture and bacteria to work their way into the hoof wall or nearby sensitive structures, which may lead to an abscess. It doesn't always mean the crack is the cause, though, as abscesses can also happen with bruising, trapped debris or other hoof problems.
If your horse is suddenly sore, hotter in one foot, or you can see discharge from a crack, it's sensible to treat it as a real hoof issue and check it carefully.
Things To Check
1. Look at when the lameness or soreness started and whether it came on suddenly, as abscesses often do.
2. Check the crack for black staining, drainage, a bad smell, or a soft area that seems different from the rest of the hoof.
3. Feel for heat in the hoof and compare it with the other feet if you can do so safely.
4. Notice whether your horse is more sensitive on hard ground, turning tightly, or picking up the foot reluctantly.
5. Look for any swelling higher up the limb, which can sometimes happen if there is inflammation or an abscess tracking out.
6. Check the environment, especially if the horse has been standing in wet mud, dirty bedding or very damp turnout.
7. Think about recent work, a lost shoe, a knock, or any change in hoof balance that could have made the crack worse.
Common Causes
The most common reason is that the crack has created a route for contamination, especially if the hoof is wet, dirty or the crack is deep enough to trap material.
Another common possibility is that the hoof was already bruised or stressed, and the abscess developed separately but showed up at the same time as the crack.
In some horses, a long-standing crack can weaken the hoof wall and make the area more prone to movement, discomfort and trapped debris.
Less commonly, the problem may be linked to shoeing issues, poor hoof balance or an underlying hoof condition that needs professional assessment.
What To Do
Keep the hoof clean and dry where possible, and avoid picking at the crack or trying to open it up yourself.
Limit work until the horse is comfortable again, especially on hard or uneven ground.
If the foot is dirty, gently clean away surface mud so you can monitor it, but don't over-soak the hoof unless you've been advised to do so.
Keep a simple note of any changes in heat, lameness, swelling or drainage, as that can help you judge whether the problem is improving or getting worse.
Make sure the stable or turnout area isn't making things worse, especially if the horse is standing in wet bedding or mud for long periods.
If the crack is recurring, review hoof care, trimming and shoeing with the person who normally manages the horse's feet.
When To Contact A Vet
Contact your vet if your horse is very lame, the foot is hot and painful, swelling is spreading up the leg, or there is a lot of discharge, bleeding or a strong smell from the crack. You should also get advice if the horse isn't improving, the problem keeps coming back, or you're not sure whether it is an abscess or something more serious.
