Does anyone here have to deal with locking stifles, also known as upward fixation of the patella? My dollface of a 3 year old Paint filly has magically decided she needs to be a horse that has this problem. She was eating in the arena quietly tonight with the others, and all of a sudden Shay-la is hollering because there's Jynx DRAGGING her right hind leg behind her. She spent probably 10-15 minutes dragging it around, with it popping back into place every couple steps and then dragging again. Someone told me to back her up - every step the leg would lock, twist and then pop violently back into place.
We spent about 30-45 minutes walking her around and we finally got it to stop locking - but now every 5th or 6th step she takes, the leg buckles out backwards at the stifle joint. This is weird - a girl at the ranch owns a horse with locking stifle and they said they've never seen that before - once it unlocks, he's good to go. Jynx flat out isn't walking normal - the stifle and hock keep buckling every few steps.
Any advice? I've called the vet, no answer, it's late and a long weekend and I'm not paying hundreds of dollars to have him out on an emergency. I'm just beside myself - from what I understand, this isn't just a "fluke" occurance, she's going to have this problem for life. AND it's genetic.
I just developed a WHOLE new beef with backyard idiot breeders.
