Oh, DW, she’s lovely. And she needs help or the vets’ prognostications just may win out. From the photo of her non weight bearing, it appears that she’s got some soft tissue contracture in both fetlocks, but more notably in the limb that’s closest to the person in the picture. I’d be willing to bet that if you grabbed that little leg, you wouldn’t be able to flex the fetlock much. This needs to be addressed and quickly. In the simplest terms, her body has decided that the current joint alignment will be the status quo, so it’s strengthening the tissues in that position. She can’t possibly “come up” if her own tissues are firmly holding her fetlocks in the hyperextended position. Her pasterns are likely a bit “frozen”, too. Add in the obvious inflammation in those little fetlocks and you’ve got a recipe for a lifetime (and not a long one) of bearing weight on the fetlocks.
The next things that stand out in the pictures are the shoes. They are way too short. Another poster mentioned wedged shoes. If she weren’t contracting into the hyperextended position I’d be all for that, but when the tissues are tight, you can get stretching at one joint, but not at the other related joints and end up with more problems (like stretching and weakness at the coffin joint with jamming forces from immobile joints above = bad). I’ve never been a fan of cup shoes for a number of reasons, but mostly because they don’t allow for much expansion of the hoof. Baby needs to be on those feet and her walls and heels need to be free to flex. But, they’re better than nothing.
I don’t know if anyone has the time, but manual stretching of the fetlocks and pasterns would be tops on my list of necessary therapy for these legs. A pair of dynamic splints would be ideal, because they could release the contractures and provide flexible support at the same time, but as I shared earlier, availability is an issue. Do you have any Back on Track wraps, DW? As I’m sure you know, heat is your friend when releasing soft tissue contracture. As is motion and reduction of inflammation.
While exercise IS great for both laxity and contracture, walking on the sesamoids isn’t good for anything. I believe she’s still hospitalized, so you have vets making her daily exercise calls and don’t need to worry about her daily management just yet.
If she were mine and I couldn’t get dynamic splints, I would work those tissues loose as soon as possible. In between massaging and stretching sessions, I would try applying a thick, wedge soled flip flop to each hind foot. I might leave the little cup shoe initially, as it could make taping the flip flop sole in place easier. Here’s a picture of the kind of flip flop I would start with:

And I would get it big enough to stick out behind the fetlock a little. Measuring from the baby’s toe, along her sole, up the back of the pastern and including the fetlock joint, I would get a feel for the length of shoe I need to start with.
In this case, I would be looking to physically “wedge up” her pasterns for a little while. I would cut off the thongs and then position the little foot near the toe so that the rest of the sole runs along the pastern. Before taping, I would employ gel padding of some sort - medical grade gel cushion, cut to fit gel saddle pad, bicycle seat gel pad…you get the idea - to build the wedge to the degree needed. Carefully applied gel helps build up the wedge toward the heel of the shoe, providing a near normal angle for the pastern and a soooooffft, squishy resting spot for the fetlock. Aaaaah, sweet relief for the poor little sesamoids.
Tape your gel in place and either cover tape with something nonsippery - Vetrap, drawer liner, sports grip tape - and/or wrap the baby’s leg and foot with a non slippery, i.e. Vetrap finished, bandage.
Once you’re happy with the degree of angle and padding, Elasticon and duct tape become your allies in securing the “device” to the little leg.
Sorry for the long post. I’ve seen so many of these that I can recognize, even in a photo, when they’re not progressing as they should be. I don’t mean to be too blunt, but more needs to be done for this baby ASAP and it bears repeating, loosening up the tissues is of utmost importance. They can’t possibly tighten up in the correct alignment if they’re already tight now.
She is darling. I hope this is all just a bad dream very soon.
