My 18 month paso fino filly was diagnosed with UPF. It doesn't bother her while she is gaiting, but when she is standing, she frequently "locks up" and can't bend her leg. This is particularly noticable when I try to pick her back hooves up. The vet did rule out stringhalt. You can sometimes see it when she gallops.

Because of her age, she is too young to ride, the vet wanted to inject her with a steriod and acid (HA?) as opposed to trying to blister her. I want to do something because she gets so frustrated. I do ground work with her and she wants to obey, but the leg gets stuck. She can unstick it herself, but it takes a second.

Do you recommend this? Is this hereditary? Would she not be a candidate to breed later on? I did read the articles on your site.

Hello Lynn,
The article does list our recommendations. They are presented in a step wise fashion starting with the order we do these things. I do not know how HA and steroid would help this condition.

The heredibility of this condition is unknown and we think that some forms are and others not. If you can fix this without resorting to blistering or surgery, it probably has low hereditable characteristics, otherwise this may be related to conformation/anatomy making it hereditable.

What would you recommend in a case like this? I would say she is probably a moderate UPF. She definitely locks when trying to move sideways and back. Now that I know a little more of what to look for, I think there is strumming when she is galloping. I want to do what is best for her. I know she gets frustrated (and she can have quite an attitude!). She always tries to please, but when she can't do it, she gets cranky (like backing away from the stall door to admit a person).

What would you do if she were yours?
Thanks for the advice.

I would start at the top of the list of our recommendations in the article and work my way down the list. It is written as a step-wise treatment regimen to minimize the chance of complications of treatment.
