My 6 1/2 year old mare has a large scar on her right knee. I was told that she aquired it as a foal and that it only was a skin injury and that no muscles and tendons were involved. So far that has seamed true, she has never had any kind on lameness or stiffness in any of her knees. She has however from time to time devoloped strange sores on her scar. At first I thought they were simply puncture wounds, how ever they have returned several times since then. These pictures are from the worst time and I got out alot of junk (puss, hard chunks . . . Yuck) and once treated it healed very quickly. May I also say I was gone while this wound developed, if I was home I would like to think it would not have gotten this bad.
Ouch. I would talk to a vet and see about getting an xray. I know someone else mentioned it in another thread, the possibility of there being some kind of bone fragments or some infection near the bone that needs excised.
It makes me think something is in it or there is an infection. My QH had a hole in his face that used to swell and then puss up and drain, for YEARS. I was told it was a puncture wound. Had the vet out several times, he actually said (2 different vets actually) said that it looked like a man made hole, maybe for sinus drainage. His face did that for probably 10 years off and on. About 5 years ago I took him to get a root canal (on a vet's suggestion - ANOTHER one) and geuss what... All those years, it was a toothe. The reason the hole stopped opening and oozing was because the tooth had finally died. When they went to do the root canal the tooth actually fell out in the vets hand.
So... I geuss the moral of the story is, check the obvious but don't rule out the stranger possibilities either...
Not to scare you, but that looks a lot like my mare's stifle injury that she had when she was 3. It was called a sequestrum and it was a piece of dead bone fragment that was irritating the muscles and bones around it. She had hers for about a year and it would continually come open and never quite healed. We had hers removed by surgery and she has been fine since. HOWEVER, sequestrums are pretty rare. So rare that my 45 year old vet had never seen one in person. So it is entirely possible that it is something else. Definitely have your vet check it out asap. Reoccuring wounds are never good.
Yep, your story and the wounds would indicate that your horse likely has a sequestrum from an old wound. You need to have your vet out to x-ray the area to see what is causing it. Likely there is a piece of dead or damaged bone that needs to be surgically removed. These can continue for years if left untreated.
There is a foreign body in there that the body is trying to get rid of. It is actually quite common to see stuff like that, although usually the wound just never entirely heals, instead of healing and then opening back up. Call the vet yesterday!
Sometimes with flushing you can get the sequestrum out, but it usually means surgery to get rid of that.
Depending on what the X-rays are like and the shape that the bones are in will determine what the prognosis is like..
