Frustrated would be a nice way of putting how I'm feeling at the moment.

Little history; horse has consistently bowed/floated out of 1st barrel turn. Got worse over time. Vetted, injected si, hocks, coffins.

No change. Vetted again. This time with lots of blocking. Found some suspensory tears and forelimb lameness. Injected coffins and bursa. Made the decision to go ahead with bilateral hind suspensory fasciotomy and neurectomy. Followed by a lot of stall rest, rechecks, legging up. 

Last recheck was done a month ago; hocks positive, stifles slightly positive. Injected both. 

Got the clear to start running. Made a couple practice passes, no change. Entered first time this weekend, no change. In the video you can clearly see him not wanting to stick the inside leg and turn, he's bunny hopping. Then fading out so much he's basically running sideways between 1st and 2nd. Never truly extending that right hind throughout the whole run.

He has another appointment with the vet next week. Luckily the video was taken at the perfect angle to see exactly what he's doing. But I'm curious, has anyone had a horse who's done this? I mean the hind end literally floating and staying that way between barrels?

I rehab at least one or two suspensory injuries every year, they need a lot of aggressive rehab. I don't recommend fasciotomies.

how many months of rehab were done ? Were any regenerative meds used ? What does the before and after ultrasound look like ??

if you didn't inject hocks before you started running I'd bet this is a big part of the problem.

Surgery was beginning of November. After 2 months of rest we did 4 weeks of only walking, 4 weeks of Trott, 4 weeks lope. 

He's had everything injected including hocks and stifles last month. He had hocks done before as well. 

Yes they did the prp (?) Not exactly sure what it's called where they inject his own stem cells. This was done twice

From the history given, especially with just 2 mo stall rest, I wouldn't expect the suspensory lesions to even be close to healed.Ultrasound should show some fiber alignent and no hypoechotivity before anything but hanq walking starts.

I would get another vet to look at the horse. A girl that I know had three vets look at her horse and the fourth one found something different. Horse seems fine now. 

It was 2 months stall rest then 2 months just regular pasture exercise. Sorry should have added that.

This is one of the best performance vets in our state so I completely trust his knowledge and judgment. I feel like now that we got one issue taken care of we are now realizing that maybe that wasn't exactly what was causing him to do this. I'm wondering if a stile issue would make one float out like that? Like I said, he's being seen again next week but I'm just curious is anyone else had one that did this because I've personally never seen it before until I got this horse. 

Suspensory tears take a long time to heal. I had one off for 8 months and she still wasn't 100%. She did come back but it took a while longer. 

I would get a second opinion. 

I agree with others regarding timeline. My horse had a suspensory tear and he was off for just shy of year before we even thought about slowly bringing him back. We figured he was done due to the severity of the tear, but we monitored it via ultrasound every few months and he ended up fully coming back.

I haven't had a suspensory injury, but I have had two horses with tendon injuries. One took almost a year to heal and the other over a year and a half.

I know you said horse was cleared by the vet to run but ..... if horse is still not right, then something is still not right.

Think I would get an opinion from another vet. 

There's a lot of good information on this thread. Suspensory injuries are tough. When I had one, what I did was inject with Renovo, wrap with Runners Relief, and do weekly Magna Wave and Laser treatments along with ice boots. We would do checkups every 30 days and ultrasound to monitor the progress, or lack thereof. 

They heal VERY slow, 6 months strict stall rest at the very minimum for a few torn fibers. It is heart wrenching. Keep in mind, these horses do not always show lameness in-hand. Lameness can appear by refusing the alleyway, reluctance to turn or keep leads, blowing off barrels, bunny-hopping.

Second opinions are always a good idea as well. Someone may see something that was missed. No hard feelings. The goal is a sound, happy horse. Good luck! 

Thank you all for the suggestions! He was seen again last week and I guess he has/had Proximal suspensory desmitis. Basically he had old injuries that healed but would get inflamed and cause pain?? This I how I understand it anyway. So with the surgery, he can no longer feel the top higher portion of the area. He has completely healed from this and feels nothing. Specialist feels it's not his legs still causing him to be back/hind sore. We had already done hocks and stifles a month or so before but he was due for si. I gave a list to the vet of what I was feeling/seeing; not wanting to us hind end, sit or really stick his right hind in to turn. He swings hind end out when turning right, and basically runs side ways halfway to second. He leans on the Farrier, zero help holding himself up and doesn't want to stretch out. Shifting weight a lot and holding his right hind cocked out when standing. 

This time, with his seeing how he stands with this leg cocked, the mention of the Farrier issues etc he suggested injecting his hips. Is this the same as whorl bone injections? 

We did go ahead and give it a go. I get on him for the first time again today. Wondering if anyone has any experience with hip injections? Basically at this point, if I do not see any improvement I will have to move on, he's just costing too much for very little if any improvement. Also wondering, this is my first appendix barrel horse, I'm wondering if because of confirmation in these horses, if they just tent to need more maintenance to keep them going.
