The short answer is: No one really knows.
The long answer is…
Nilla has a history of hock arthritis. With injections, Previcox, and Osphos on board, I felt like we finally had them managed. She won Best Condition at two different endurance rides and those were judged by vets so I feel like my belief that she was sound wasn’t completely subjective.
However, when Nilla developed ulcers back in July, I took her off Previcox. As July passed into August, Nilla’s hocks were getting worse. Given that she was injected last year in September and injections can last 6-18 months I figured she probably needed injections again. But I was concerned that they wouldn’t be enough. When I did injections last year, they didn’t really work. She almost got pulled at Quicksilver a few weeks later.
When we left Camelot, my husband asked me what was next for Nilla and I said, I don’t know. While she was mostly sound, there were moments at the event where her back end dropped out from behind her. She would just stumble, then keep going like it hadn’t happened. She did this last year before the injections so I figured it was her hocks again.
After she nearly failed the vet check at Quicksilver, I had my vet do X-rays. When she did the injections, she wasn’t able to get the full injection in on Nilla’s right hock. The X-rays revealed that her right hock was partially fused in the middle making it difficult to inject. We discussed doing an injection into the joint from the front, but it’s a dangerous injection to do for the vet with a lot of risk of getting kicked. And Nilla has already proved herself to be risky to inject.
You see, mules are weird to sedate. They usually need more sedation than a horse of similar size. When getting dental, Nilla gets 2x the dose of the horses and she’s basically awake the entire time and just tolerates the dental. However, if you give Nilla a ton of sedation, she starts falling down. She’s still awake enough to fight you if she doesn’t like what you’re doing, but she’s now stumbling on her own feet. None of this makes her easy to inject. And outside of not wanting your head kicked in as the vet, the constant stumbling movement makes injections difficult.
I would need to take Nilla in to a hospital with stocks to do that injection. We ended up adding Previcox instead. And then Nilla kicked her leg through a metal trailer door and fractured her pastern. That was fun! Nilla got some time off and came back doing pretty well. We added the Osphos in May and then did the two rides winning BC. Then the ulcers ruined everything.
So with that lengthy, complicated history, I decided to take her to a different vet. This vet has a hospital and would be better set up to do injections from the front or some other procedure if that was advised. It’s a pretty fancy place, so I went in figuring it was going to cost me. When we got to the point where two techs and three different vets were working on Nilla, I started feeling like maybe my poverty estimates weren’t extreme enough.
On the plus side, Nilla thought this place was amazing as they had real live grass. This is basically unheard of in California in the summer.
Anyway, they did lots of palpitations and trotting and flexions and trotting on circles and more palpitations. The vets were a bit concerned about all of the scar tissue in her pastern area. Apparently that part of her leg was “crunchy.” Yeah, that’s a word you want to hear from your vet. It wasn’t a problem though, all the soundness issues were in the hocks. So we progressed to X-rays.
The vet thought the X-rays showed that she clearly needed injections, but her hocks weren’t too bad. Because she’s such a problem, Nilla got extra happy juice and a twitch for the actual injections.
My vet had also injured her finger so the head vet was called in to do the actual injections. As they were conferring after the injections, I realized they thought her fracture from the trailer accident was in her hock. No, I told them, it was down in her pastern. The reason for that confusion? She has a fracture in her hock. It’s not new; it could have been there for years or it could have happened when she kicked her leg through the trailer door. We never X-rayed that high on the day of the injury because all of the cuts were lower down.
This fracture is scary. It’s where the suspensory attaches and calcification/bump from it is possible irritating the suspensory. But it’s also possible that it’s not bothering her at all. Hell, it could be an injury from years ago. We don’t know (my short version of this story). Given that she was sound and completing endurance rides post accident, it’s very possible this fracture isn’t effecting her at all.
Right now, the plan is to give her a week off post-injections and then she goes back to normal work. We’re also going to resume the Previcox as apparently it’s not that rough on stomaches and her ulcers are under control now. In 3 months she should get another Osphos injection. If she stays sound, we go on with the idea that the fracture isn’t bothering her. If she can’t stay sound, we re-evaluate.
I feel like this is a real-life Schrodinger’s Box. Right now, the bandages are still on and – in my mind – Nilla is simultaneously sound and retired. The only way to find out is to wait a few more days and then ride her again.
Fingers crossed the cat is still alive.
Well that’s disheartening. She’s done so well this year! I had to put Irish back on the previcox and he’s doing well so far (no colic). Maybe a gastric supplement to go with would help?
She’s on a bunch of gastric supplements now and the ulcers weren’t caused by the previcox, they were caused by her trailering anxieties, so I’m hoping the supplements will allow her to tolerate the previcox again.
Poor Nilla. Hopefully she returns to pre ulcer soundness and all can be filed under “interesting but not to be thought of again”. Hard to believe she could not only complete but get BC with a painful fracture.
It’s possible that even if the fracture happened at the same time as the pastern fracture, that in giving her time off and meds for the pastern, the hock also was healed.
oh no 🙁 Poor Nilla, I wouldn’t have expected this at all after such a great year. I hope everything works out as best it can.
She’s had a good year, but I’m like Ariel; I want more.
I’m devastated to hear this. I’m paranoid about Copper’s hocks not being aided by the injections myself, so I am on the same page with you about the sound and retired bit. 🙁 If you ever want to talk hock drama, let me know…I can sympathize…
I think most horse people have been through the hock wringer. In the years I’ve been doing them, they are usually super easy and work. I’ve never had as many issues as with Nilla. I wouldn’t worry with Copper. I’m sure they’ll be easy and work for him.
I really, really hope the injections and the re-introduction of Previcox takes care of everything! It is so hard waiting and not knowing. You are doing everything you can, so fingers crossed for a good result!
Hopefully she’ll be feeling good in a few days.
OI horses. thats scary about the hock fracture. i hope what youre doing helps!!
previcox is magic <3
Yes, I’m really excited to have her back on the Previcox. She was doing pretty well with it.
Poor Nilla. I have done my fair share of the Lame or Not game. I hope it turns out well for you.
I think it will.
So many hugs for you and Nilla. Crossing my fingers tightly that she comes out of this sound, and able to lead a normal show-Mule life!
Well that’s a kettle of fish. Fingers crossed for you.
Oh man what an emotional roller coaster this is 🙁
Fingers crossed indeed I hope she is feeling better soon.
She would tell you she feels fine. The vet’s word was stoic. She does not want to admit to anything being wrong.
I went through a lot of hock drama with Simon. It’s really frustrating, but there is often light at the other side! Especially with fusing. Fusing sucks, but once they fuse… golden!
Yes! I really just want her hocks to fully fuse.
I know in the midst of this it sounds terrible. But honestly from what I’m reading, I think there’s a pretty good chance she’ll be feeling better with the injections. Also previcox is magical. As long as you’re managing her tummy, I think you’ll be ok with it.
My old horse Rio is on it daily, and I recently put him on Relyne for his stomach because he was having a lot of loose poo. May or may not have anything to do with the previcox, but it might be something to look into to keep Nilla’s tummy happy. It’s not cheap, and you need prescription for it, but it’s been great for Rio. My vet loves it too.
I’m guessing the Previcox will work again. I think if I keep her on all the ulcer prevention stuff going forward it should be okay.
I think the waiting is one of the hardest parts. Fingers crossed that her little joints respond beautifully to everything and that y’all can continue doing what you enjoy. <3
The Heartbreakers had it right.
Praying and crossing my fingers for y’all! So rough going through stuff like this with our equines 🙁
Horses do like to torment us by injuring themselves.
oh man, i’m so sorry to read this Olivia! finding an unexpected fracture is…. wow, i really can’t even imagine how you felt learning that one. hang in there – hopefully she responds well to treatment (or fuses up quickly!)
Fusing would be excellent.
Wow, that news sucks. Fingers crossed that she’ll be better than ever once you take off the bandages.
That’d be awesome.
Ugh. That gray zone of the waiting game, where you hope for the best but conjure up all the worst scenarios in your head. Hoping she’s all good in a few days 🙂
That’s exactly what I’m doing. Cycling worry through my head.
Yikes! Feel better soon Nilla!
Man thats a wallop to well intended plans. Hocks are tricky, especially for our beloved horses (or mules) that we want to keep riding and showing. Its a hard line between doing whats right and doing what we want. I hope Nilla makes the answer easy by healing fast and bouncing back just fine!
I hope so too.
I’m so sorry to hear this. I hope the injections and Previcox work! I’m having super results with ethyl alcohol injections in my old man’s pastern to speed up fusing. He went from so lame I though he was going to have to be put down to cantering out of his pen after the first round of injections.
I asked this vet about that and she said they don’t do alcohol injections because they’re “old school” and painful. But I feel like they really just don’t want to do them because then I’d be done and not paying them a ton of $ for super expensive regular injections every 6 months.
Oh god I totally know how you feel. Riesling was supposed to be 100% on Saturday and just wasn’t. But the x-rays showed that besides some unbalance in the coffin bone his legs are really healthy. So possibly a soft tissue injury?? God, horses can be so difficult.
I swear horses think injuring themselves is a fun game.
