Cinna came in sound, but with a large leg and a scab. X-rays showed that the bone and joints are fine, and that basically it appears to be mostly scar tissue from the wound trying to heal, but likely not with any veterinary care. Ultimately the scar tissue built up to the point that the wound stopped trying to heal.
Nebraska Equine Veterinary Clinic was able to go in and remove a bunch of scar tissue and bring the skin back together, which should
allow it to heal finally.
