WhoaNow, I'm not sure what you mean by sharp and long fetlocks? Are you referring to the angle and length of her pasterns?
I can absolutely buy the conformational predisposition to soft tissue problems--lord knows I've quizzed the vet about a dozen times on the very subject, to his great exasperation....and utter denial. But vets, even good ones, aren't always right about those things. And it would make more sense (and make me feel horribly guilty) if we could tie in the lameness to barrel racing, either through a specific incident or an accumulation of overuse. But again, every time she's come up lame, it's been after pulling her off the pasture. I do think there could be something to the theory that she had minor, subclinical desmitis of the DDFT, acquired during competition, general riding, running around the pasture, or whatever, that was then badly aggravated by the overloading of that leg due to the opposing abscess (and she was, indeed, quite happily galloping on three legs when the right abscess was so painful she couldn't even put the hoof down). If I'd known, I would have kept her up those days until the abscess burst, but then the vet had said to turn her out to help speed the process along, and hindsight IS 20/20.... When the vets at the hospital saw her MRI results, they couldn't say whether the three tears happened at the same time or separately. And they were amazed she was as sound as she was, given the severity of the injury.
