All depends on what sort of injury, split tendon or sprained. Hind leg injuries are not as bad as foreleg.
My horse split is DDFT in his hind leg and had an tenoscopy. It took 18 months of rehab, but he was ridable afterwards and we went back to being very happy hackers.
I also believe that extensors are not as bad as flexors.
The vet school said that regular gentle exercise in hand was better than solid box rest to avoid adhesions forming in the healing tendon.
It all depends on the type of injury, but I would be optimistic on the whole.
I'm not sure which tendon is called what, but my boy injured the one in his hock, where you would see a thoroughpin.... that was nearly a year ago and we got over 60% in prelim dressage tests a couple of weeks ago... (and plan to do some showing soon! Touch wood!!!)
He was never lame in walk though anly in trot on a slope or circle, and he is only 5, so has age on his side...
So, as said above, it depends on the individual, but good luck with yours!! Stay positive!
Mine severed hers after being kicked. She's 26, fully retired, and only 99% sound on a good day (you might call her "field sound"). The vet didn't want to give any treatment (basically surgery) and advised that I left it alone.
So we left it, and treated the cut. She's as sound as she ever was and can still prance about the field in an extended, elevated trot.
Same horse also injured the extensor tendon in a front leg, which was less severe and healed with no problems. She can still show off an extended trot.
Obviously not a good thing to happen, but better than a flexor tendon! Prognosis is generally good, I think.
Thanks for all the feedback! It's not my horse who has done this injury thank fully, it is a horse that I am going to see with a view to loan. He did it some time ago - he is only 5 and does not seem to cause him any problem - so I have been told, but I get the impression it was pretty horrific, he completely severed the tendon and had to have skin graphs. Just wanted views as need to know what potentially I might be dealing with. I am looking for something that I am not going to have problems with - had to many with my own! Also insurers won't insure either hind leg - how would I stand on a loan basis with this?????
Not sure how you would stand with view to loaning, I guess you would need to have some sort of legal agreement written up.
My vet wrote to my insurance company stating the injury should not stop my mare from doing what she was intended for ( all RC activities). Her leg is not insured for anything relating to this injury but is covered for accidental injury
