She does have clubbed feet but not from the injury itself, its from years of bad shoeing we thought was helping her (natural balance). If kept her comfortable, but kept any progress that could have been made early on from happening and messed her up in the long run. We are slowly trying to take her heal down without causing her soreness (2 years in the process of that).
The reason it may look uneven is because the x-rays weren't taken at the office, but rather with a transportable x-ray machine, maybe that could have caused the way she is standing. Or possibly because she was standing without shoes and is very sore without them.
As for the deterioration, I honestly don't know. The vet did mention the onset of arthritis, and a couple of years ago we were told her bones had grown deformed because of the injury being so early on in her life. Maybe that's it?
As for pain, she's very, very rarely in pain so extreme she needs to be medicated, though she is on a low dosage of pain medication that is in the only supplement she takes that we swear by. She never has problems walking, trotting, cantering or running though her gaits are different, stiffer and like I said she does limp. She's has had abcesses in the past, and and thrush rather recently and those are the only times we've had to use pain meds to help her out, and the only time any vet has recommended we use pain killers.
I'll try and remember to take pictures tomorrow of her hoofs.
