without a thigh bone you wouldnt be able to walk, imagine; if you took out your thigh bone, 1) you would be a lot shorter 2)the upper part of the leg would be like flabby jelly and 3) it allows are legs to move etc. it also take some of the human weight, if your thigh bone wasnt there, you would collapse on the floor, and you would have to crawl using your hands
