Big Bump on Leg

[mypaintpony]

Here are some photos. My mare is not lame and hasn't taken a lame step. Is is some kind of splint but aren't those usually in different places? There has been no heat or swelling of the knee. It's very hard and feels like it's part of her bone. Kinda looks like a Bone Spavin but it's not on the rear leg.

Does anyone have an idea of what it could be?

Looks sort of like a splint to me.

I've looked online and read about splints but they seem to be in different areas of the foot not underneath the knee. BO doesn't think it's a splint so that's why I am wondering.

I'm going with splint as well & here's a web page with pictures ;)

Well, what does Barack Obama know about horses anyway?! :rolleyes: I think you're BO is full of BS IMNTCHO.

That's a classic splint. A "splint" is from trauma to the splint bone, or the interosseous ligament that binds it to the upper 2/3 of the cannon bone. Swelling of the ligament and bone usually calcifies leaving this bump.

I put forth another vote for a splint.

Sorry, BO

Yep, that's a splint if I have ever seen one (and I have on Muffin and other horses).

If it's recent, It should or could be warm and tender to the touch but not always. Rest is best to let the bone and tendon go back in to place. splint boots for any kind of work, riding, lunging or playful turn out time.

Splintex for new splints can be used to help so it won't calcify leaving a permanent lump or for old splints that are already permanent you can use the Splintex made for old splints that helps soften the outer layers of the lump to reduce it's size while the body absorbs the extra calcium.

If it's new I would think about how it could have happened. Hard riding lately? Turn out with other horses that could have caused an injury? Jumping or stumbling? Banging in to poles, fences or rails? Let the horse rest and see if it goes down in the next week or put splint boots on and only very light riding. If you feel it's not going down then you can get a bottle of splintex and start using that on it. Read the label and use it as directed only on the lump area and sparingly. But, I would only use the splintex if it didn't go down after a month of light riding and rest.

Thank you all. I am going to go along with you and say it's a splint.

Taz has a splint in the same place on his left front. He's had them since before I bought him. Does not affect him at all. What I have heard is that splints are common in horses that have been worked hard at a young age, horses that have been used for jumping, or galloping hard over rough ground.
