Thistle is a molly mini mule, that, as a long yearling, broke her femur right at the stifle end growth plate. It was misdiagnosed as a major tendon/ligament issue - she already had moderately severe locking stifle issues, and the initial xray didn't cover where the break was. After five months with no real progress - I know tendon issues can take a long time to resolve, and the vets kept saying, "tincture of time" - I got a second opinion. Long story short, she immediately had surgery (late Feb 2016, included a human grade plate and four screws) and is now just past the six month mark post surgery. The break is healed, but due to the delay, she had both bony growth and resorption in the patella and parts of the femur head, causing significant arthritis in that joint. Her patella, in particular, is pretty gnarly looking on Xray, but the doc said she'd end up with more problems if they "cleaned it up to look pretty on an xray".
Flu-Nix is a nonsteroidal anti-inflammatory drug (NSAID). Flunixamine is used in cattle for the control of pyrexia associated with bovine respiratory disease (BRD), endotoxemia and acute bovine mastitis, and for the control of inflammation in endotoxemia. Flunixamine is used in horses for the alleviation of inflammation and pain associated with musculoskeletal disorders and for the alleviation of visceral pain associated with colic. Each ml of Flu-Nix contains flunixin meglumine equivalent to 50 mg flunixin. The recommended dosage of Flu-nix for cattle is - mg per kg (1-2 ml per 100 lbs.) given by slow IV, either once per day or divided into two doses given at 12 hour intervals for up to 3 days. The recommended dosage for horses is mg per lb. (1 ml per 100 lbs.) body weight given IV or IM once daily, and repeated for up to 5 days. Not for use in dry dairy cows or veal calves.
