It could have been a car accident deer and had a bone injury. I have a fine 8 point on my wall over my computer desk that I call the cripple buck. It's femur was sticking out of it's back right leg/broken and gimpy. The hoof was folded under and it was locked. The buck walked on it, the top of the hoof was scared over. The bone sticking out was healed over and he still grew a normal rack. The injury had to be an year old.
