The vet was out today and took x-rays, as I said in my last post.
When he got kicked or what have you back in December, it caused a small fracture or something. Long story is there is a new bone chip on the outside of his right hock. It isn't causing him any pain (he's not lame), but it is irritating the soft tissues around the joint (hence the swelling that just won't go away). Eventually his body will start to lay bone around it to "protect" him from a foreign object, which will cause the joint to fuse and Mikey to be permanently lame.
To me, that's not an option for him. He's a hard working horse that genuinely likes to work. He's also only 16. He has another 10-15 years left, and I refuse to let that be as a lame pasture pet. Aside from the fact I can't afford to keep a second horse, he's my buddy. I've had him for 10 years. I set money aside for a rainy day when I was in college, well it's finally raining.
I only have that minimum information, the vet will call me later today to discuss where and when for surgery, go over risks and recovery, etc.
Has anyone had bone chips removed?
