OMG! My AQHA gelding is going to be the death of me, and it has nothing to do with riding.
I have now experienced, although not seen all, 3x that he has injured the same lower leg. Several years ago, I found him with a huge gash on his heel, assumed he stuck it through the fence (we have cows, so barbed-wire); then a few years after that the same leg with the scarred area gashed open again. And, now this morning, he was standing with the same leg through the gate to their paddock, just a couple spots of blood, so no major damage; he would not pick up his leg to step back out, so had to drop the gate, and the mare promptly took off out the gate, he still wouldn't pick up his leg to step over the wire, I finally stepped on the wire, and pushed him back over it, closed the gate, got him interested in breakfast, and got the mare to return for breakfast. I had to go to town today for appointments, so will get a closer look tomorrow at what he did to himself this time around.
