you are absolutely correct, if this was something that has happened more than once then yes, further investigation would be taken. However this is the first time since the original injury she hasn’t felt right after torquing it. She is back and fine after using DMSO on the leg. Wrapping and IRAP injectons is exactly how I was rehabbing the first time. Instead of injections I used DMSO. If this becomes a reoccurring issue absolutely will I have another set of x Rays and ultra sound done. But given she was fine the next day, the treatment either worked or it was unrelated. She is an OTTB with some normal wear and tear almost every race horse has, so I baby her legs to begin with. Perhaps if I didn’t use DMSO she would have still been fine the next day. There were many factors that could have caused her to not feel 100%. Im being over protective and just assumed this was the situation. Regardless she is fine now…so I better just smile and be happy lol 
Back in the day at the track we did sweats without DMSO. Apply Furacin, cover with sheet cotton, saran wrap then standing bandage. Worked great.
Thanks for clarifying the number of recurrences - several of us missed that
I think we focused on " Unfortunately she is fragile and if she takes a blow to it hard enough (i.e. Knocks with her hoof or other object) it gets sore as any leg would compromised or not." which made it sound like this had happened at least a few times.
You’re right, she might have been fine without the DMSO 
Honestly, me, I’d just ice it if I thought she whacked it. Simple, safe, effective.
If she’s involved in an activity (newer to her, longer duration, etc) where there’s an increased risk of whacking her leg, use splint boots.
Yes, I apologize I wasn’t very clear and made it seem it has happened more often. Although everytime she takes a lame step I wig out thinking it’s relatable even if it’s a hind leg LOL. Took her almost a year to rehab/ecover and get back to where we left off. Seems like we’d take a step forward and 3 backwards so kind of explains why I’m overprotective.
She actually pretty much lives in splint boots
Any turn out or work she is either booted or wrapped with exercise quilts and stretchy bandages. She pretty much doesn’t leave her stall unless she has protection. I’m sure she hates me I will definitely ice in the future…I feel dumb for not thinking of this. I even have ice wraps I specifically got when rehabbing! Thanks so much for providing your opinion and giving some good ideas!!
Have you consulted with a reputable farrier to determine why she popped a splint in the first place?
I would ask…
Did hoof imbalance play a role?
Why does she continues to interfere?
What, if any, shoeing solutions are possible to help your horse?
csaper, she said “My horse had popped a splint during her race days”. Very, very common.
Even my TB mare popped both her fronts within a few months of being here and racing around the pasture. Not at all surprising. It’s not uncommon for younger horses to pop 1 or both while farting around the field.
But it’s a good point about looking into interference. I’m not sure if the "pretty much lives in splint boots " comment is because she wings and frequently hits herself, or if it’s just Mother Hen over-protection :winkgrin: If she does wing (toed out) then it’s worth investigating if it’s conformation or trimming.

I saw that.
I would wonder ‘Why’?
My horse popped a splint at 18 months in a pasture ‘joie de vivre’ moment.
It healed, is nearly invisible and has never bothered him again.
If this is an on going issue it is worth having a specialist in corrective shoeing look at the horse’s confirmation and feet to see if any help can be offered.
Why? All it takes is the wrong step and the leg twists just enough to pop it, especially when they are young. I wouldn’t think twice about a horse who popped a splint while in his racing life.
Thank you Csaper58, she is already in corrective shoeing from when she reinjured per reputable vet and farrier. Although I’ve been told I may go back to regular showing I decided to leave her as is and not change anything since it has helped. I know exactly why she injured the splint in the first place as well as reactivated the splint and it has nothing to do with shoeing or hoof balance, but thanks for the idea.
And yes JB you hit the nail on the head…overprotective mother hen :lol:
I just wanted to repeat this…
If an old splint is (still) causing problems, it needs to be xrayed to see if it’s interfering with the suspensory ligament, or is doing something else, and needs to be removed.
And having a horse that came to me with what looks like a bandage bow and scaring on the back of the leg, I would never wrap over straight DMSO.
I want to repeat as well this was a one time thing. She was not lame, just did not feel right and could have been completely non related to the splint. But thank you.
Also how would DMSO cause a bandage now?
I am also confused as to how scarring and a bandage bow have to do with DMSO? Straight DMSO (with wet legs especially) may cause irritation/pain or possibly minor swelling in certain horses, but would certainly not cause permanent disfigurement.
