Horse Veterinary Questions? Ask an Equine Vet.
Hi, this is Dr. Gabby. Anytime there is an infection in the joint the infection can damage the joint cartilage and cause arthritis. The only way we would know for sure if there is damage to the joint cartilage is to take an x-ray.
Do not panic though. I have seem many horses have infections in their hocks and not have joint damage.
You could also call the vet who examined her and as if the vet thought the infection was in the joint.
If the infection does not seem to be resolving your vet could always do a culture of the bacteria to see what it is sensitive and resistant to.
Also if there is a wound over a bone that will not heal and it had a draining tract it is a good idea to have an x-ray done to make sure there is not a little bone fragment chipped off and holding up the healing.
Does that help? Do you have any additional questions?
