spavined

As for the wonderful feats of horsemanship one hears of or sees among the Arabs, they are due to sharp spurs like razors, and to bits strong enough to break an animal's jaw. … Their favourite feat at their fantasias or fêtes of suddenly pulling up their horses short while at hand-gallop, ruins their legs, and there is in consequence scarcely a horse to be seen whose hind-legs are not spavined.

I’m a spavined old warrior, and I don’t have much time left in this world, but I still have a few tricks to teach these whippersnappers.
