Ok, so since we still haven't received the call, here comes the next update.
Like I said, Lily's hooves are fine. But we decided to radiograph the left hind fetlock too, and discovered 2 things that we're not sure yet if they are badness. All we know is that they are things that should not be there.
Here are the rads:
|Left hind hoof, no dye. Look at all that sole! She only had 1/8" of sole between her coffin bone and the outside world back in October!|
|Left hind with contrast dye injected into the puncture wound hole. It's not deep at all! Yay!|
|As an afterthought, it was decided to radiograph the fetlock, just to rule out that there weren't multiple causes for the swelling. And here we started finding stuff. *sigh* There is this bump that Dr. R pointed out and I have circled in red so you guys can see. She thinks it might be a bone bruise or cyst, which could be an indicator of OCD (osteochondritis dissecans), which is probably the one thing I never would have expected to find on my small 15hh mare, and it is less common for it to show up so low on the leg-usually it plagues stifles and hocks. The first link is about the disease in general, as it also affects people and large breed dogs, but here is some general info on it in horses. I don't think Lily's situation is considered bad, since this is so small, and OCD can present as HUGE joint swellings, and it can be an incidental finding where nothing else comes of it-it doesn't lame the horse, and it doesn't worsen over time. However, in many cases it does require surgery. I'm still wondering if the fluid in Lily's suspensory branches and the enlargement of her annular ligament are not soft tissue after all, but a result of what might be an issue in the bone.|
