When it happened, it presented like a bow. He was 3 legged lame for about a day. Sunday I found him that way, and Tuesday morning the vet came out to Ultrasound and see if it had indeed bowed. Thankfully, it was just a Hematoma and fluid built up in the tendon sheath. I had just bought him about 5 or 6 months earlier as well, so a career ending injury would have been devastating! Let me know what your vet decides. I'm interested!
Wow. My vet has us on limited turnout and hand-walking but not riding. He's getting cold-lasered 3x per week and wearing his back-on-track boots overnight. He just arrived at the tendon-sheath idea this evening, though, so that may change. The swelling always seems to be better after I've been hand-walking him, too. Vet had to give my boy a steroid shot for hives (it never rains but it pours...) and said if that caused the swelling to go down and then come back, it was probably tendon-fluid leaking from a small damage in the sheath. I haven't ridden my boy in a month and I really miss it. :(
took about 3 months before the leg looked relatively "normal" again. The vet said 3 things to me: ice 20 minutes in the morning, work him hard when i ride, and sweat the leg over night. I also did 4 grams of Bute for a week. I jumped him pretty big on Saturdays, and rode him hard on the flat the rest of the week. This allowed the fluid to disperse, break up and get absorbed by the body. He still, to this day looks like he's had an injury there. Little bit of scar tissue on the tendon. But it doesn't affect him at all.
I keep coming across your posts. My horse came up lame under saddle. He had a small lump behind his foreleg. Vet thought it was a sting, but then the swelling expanded up and down. Vet #1 sent Vet #2 for ultrasound, and found "mild" damage to the suspensory but mostly a LOT of fluid, none in the tendons or ligaments, and they thought the swelling would go down quickly.
Now it's 5 weeks out, and the swelling got worse and it IS getting better, but not fast. Vet #1 is now he's thinking that my horse dinged his tendon sheath, and the first bump was tendon fluid, and then it spread out. His leg looks like the pics you posted of your horse's leg.
I know you said your horse is sound now. How long did that take? Did anything seem to help? I know it's patience...but no one at my barn has had this, so I don't get the usual stuff from someone who had that very thing happen to their horse three years ago.
